[Editor’s note]

　　In order to thoroughly implement the spirit of the important instructions of the Supreme Leader General Secretary on the protection of the Grand Canal, our network actively participated in the network theme activity of "Questing for the Grand Canal" organized by the Network Communication Bureau of the Central Network Information Office. With culture as the core, we plan to launch new media products with diverse contents and rich forms, such as "Cloud Appreciating the Grand Canal", "Canal Questions", "Grand Canal March" and "Above the River", and publicize the achievements of canal ecological protection, cultural heritage protection and high-quality economic development in depth, so as to show the new features of the Grand Canal in the new era by comparing the past with the present.

　　Question 41: What is the integrity and authenticity of the Grand Canal in China?

　　As a series of heritages, the Grand Canal includes all the necessary factors to show its outstanding universal value, and completely shows the development and evolution process of the canal heritage, with a high degree of integrity in the composition of the heritage.The application for heritage vividly depicts the pattern, route and operation mode of the grain transportation system during the two major breakthrough periods of the Grand Canal in China, and jointly outlines the clear and complete evolution process of the Grand Canal in China since the Spring and Autumn Period. It embodies the creativity of traditional canal engineering and the typicality of technical system; It also fully confirms the use and function of the Grand Canal in China in the history recorded in relevant historical materials, and the various social practical values of the Grand Canal in China at present, and shows the great influence of the Grand Canal on the areas along the route in terms of use, landscape and culture.

　　The Grand Canal of China meets the requirements of the Operational Guidelines for the Implementation of the World Heritage Convention on the integrity of the heritage.The declared Grand Canal heritage shows the complete historical and spatial evolution pattern of the Grand Canal from the Spring and Autumn Period to the Qing Dynasty. The ten river sections are all representative paragraphs and nodes distributed in the heritage area, with complete and rich heritage types and large enough heritage area to meet the requirements of integrity and no defects.The various components of the Grand Canal heritage have substantial functional connections, making unique and indispensable contributions to the outstanding universal value of the Grand Canal heritage as a whole. Therefore, the Grand Canal heritage meets the integrity requirements.

　　Generally speaking, the historical pattern of the existing Grand Canal heritage from the Spring and Autumn Period to the Qing Dynasty is basically complete.The first-line rivers and sites of the Beijing-Hangzhou Canal from Beijing to Hangzhou are basically complete. In the south of Jining, the river is continuous, and some new channels coexist with the old ones. There are still continuous rivers in Beijing, Tianjin and Hebei, which play an important role in water conservancy. The Grand Canal in Shandong Province is discontinuous. According to the existing discontinuous rivers and the river remains confirmed by investigation, the main routes and complete evolution history of the Grand Canal in Yuan, Ming and Qing Dynasties can still be determined. The first line of Tongji Canal from Luoyang to Huai ‘an: about 1/3 of the river channel exists, and the sites are dotted. Among them, the existing continuous rivers and sites in Huai ‘an, east of Shangqiu, Henan Province, have been confirmed by archaeological exploration; Luoyang passes through Zhengzhou, Kaifeng and Shangqiu. Due to the historical impact of the Yellow River’s swing and erosion, it is difficult to completely confirm the river ruins. However, the general route of Tongji Canal can still be clearly defined through the partially preserved revetments, bridges and ancient river ruins. The Weihe River system from Luoyang to Linqing evolved from Baigou, Yongji Canal and Yuhe River in history, and it has been continuously used to this day. From Hangzhou to Ningbo, Xixing Canal, Shanyin Old Waterway, Yuyu Canal, Cijiang River, Shazigang and other rivers, together with some sections of Cao ‘e River and Yaojiang River, constitute the main line of the East Zhejiang Canal in history.

　　The Grand Canal has strong authenticity.The elements bearing the outstanding universal value of the heritage have good authenticity in shape and design, materials and entities, location and layout, and all the heritage elements that still have practical functions have the authenticity of use and function. As an organic whole, the Grand Canal also has good authenticity in spirit and feeling.

　　At present, the channel in use of the Grand Canal heritage still has vital shipping and water conservancy functions, which reflects the characteristics of the Grand Canal as a living heritage.Due to historical and natural reasons, the remains of rivers, water conservancy facilities and management facilities have real location, environment and materials, which reflect the design, function and technology of the Grand Canal. Urban historical water system, historical blocks and so on have real position, function and pattern, and truly bear the sense of belonging brought by the Grand Canal as the spiritual home of people along the route. The Grand Canal heritage meets the requirements of authenticity.

　　The heritage of the Grand Canal is well preserved. The middle reach, the Huaiyang Canal, the Jiangnan Canal and the East Zhejiang Canal are still navigable, while other reaches mainly play the functions of flood discharge, water conveyance and irrigation. Some rivers in Huitong reach, Weihe (Yongji Canal) and Tongji Canal (Bianhe River) are in ruins. All heritage sites, including hydraulic facilities, supporting management facilities and related historical and cultural relics, have been well protected.

　　Question 42: What is the boundary of the heritage area of the Grand Canal in China?

　　The demarcation principle of China’s Grand Canal heritage area refers to the overall planning of China’s Grand Canal protection and the planning of provinces and cities. According to the provisions of the scope of protection of cultural relics protection units and the scope of world heritage areas, the boundary of the heritage area is delineated according to the characteristics of the elements contained in each component and the relationship between the elements. The basic principles of demarcation are as follows:

　　(1) Rivers with dikes: In principle, they are demarcated according to the toe line of the outer dike, and the heritage area is a banded area including riverbed, floodplain, dike top and dike slopes on both sides.

　　(2) Rivers and lakes without dikes: In principle, they are demarcated according to the extension of the coastline of rivers and lakes by 5 meters, and the heritage area is the area containing rivers and lakes and revetments.

　　(3) Hydraulic facilities: they are included in the heritage area of the river where they are located, and are not demarcated separately. If necessary, the river boundary is partially extended to include the whole facility and its lower foundation.

　　(4) Related ancient buildings: demarcated according to the external boundaries of the buildings (such as courtyard walls and streets).

　　(5) Historical and cultural blocks: according to the regional boundaries with good features and key protection determined in urban planning.

　　(6) Sites: In principle, the boundaries of sites (such as river banks and courtyard walls) confirmed by archaeological exploration or excavation are demarcated. River sites include river beds and river banks (if any), warehouse sites include the whole structures, management facilities sites and related ancient buildings sites include the whole buildings, and hydraulic facilities sites include the excavated structures and the distribution range of their underground foundations. [Text of China’s Grand Canal Application for Heritage] chinese heritage Research Institute January 2013] After this division, the area of China’s Grand Canal application for heritage is 20,819 hectares.

　　Question 44: How is the buffer zone of the Grand Canal in China divided?

　　The buffer zone of the Grand Canal in China, in accordance with the provisions of the construction control zone of cultural relics protection units and the scope of the World Heritage buffer zone, aims at controlling the surrounding construction pressure and protecting the landscape harmony between the heritage area and the external environment, and comprehensively considers the background environmental factors related to the heritage elements outside the heritage area, and delimits the buffer zone outside each heritage area. The boundary of the buffer zone is defined according to the spatial form of the heritage areas protected by it, combined with the land use and construction status quo, and the basic principles of demarcation are as follows:

　　(1) Buffer zone around the banded heritage area: demarcated by extending the boundary of the heritage area by a certain distance to form a corridor-like landscape protection zone along the river, so as to prevent new buildings from oppressing the river and maintain the ecological safety of the river and the harmonious waterfront landscape. In principle, it is located in a densely built-up area (the built-up area of a city or town) and extends 30 meters; Located in the suburbs and rural areas, the expansion is 80 meters; It is located in farmland and a large area of water environment and extends 300 meters. At the same time, if there are more important roads, railways, rivers and heritage areas with appropriate distances, which can be used as boundaries for long-term control and construction, roads, rivers and railways will be used as boundaries.

　　(2) Buffer area around the dotted and flaky heritage area (buildings, structures, large-scale hydraulic facilities and their sites): draw boundaries according to the features or topography around the heritage area, such as roads, ditches, ridgelines, bridges, etc., and enclose the whole heritage area to form a heritage landscape of a certain scale, so as to protect the sense of space inside the heritage area from interference and maintain the atmosphere of tradition or sites. After this division, the buffer area of the Grand Canal in China is 52,747 hectares.

　　Question 45: What are the requirements for the protection and management of China’s Grand Canal buffer zone?

　　Provisions on the administration of the buffer zone of the Grand Canal in China:

　　(1) No facilities that pollute the Grand Canal heritage and its environment shall be built in the buffer zone of the Grand Canal, and the existing facilities that pollute the Grand Canal heritage and its environment shall be treated within a time limit.

　　(2) Activities that may affect the safety of the heritage and its environment shall not be carried out in the buffer zone of the Grand Canal, and the existing activities that endanger the safety of the heritage of the Grand Canal and destroy the heritage environment shall be investigated and dealt with in a timely manner.

　　(3) To carry out a construction project, the construction unit shall, in accordance with the provisions of Articles 29 to 32 of the Law of People’s Republic of China (PRC) on the Protection of Cultural Relics, report to the cultural relics administrative department of the people’s government of the province or municipality directly under the Central Government in advance to organize the units engaged in archaeological excavation to conduct archaeological investigation and exploration in places where cultural relics may be buried within the scope of the project. If cultural relics are found in archaeological investigation and exploration, the cultural relics administrative department of the people’s government of the province or municipality directly under the Central Government shall jointly agree on protection measures with the construction unit according to the requirements of cultural relics protection; In case of important discoveries, the administrative departments of cultural relics of the people’s governments of provinces and municipalities directly under the Central Government shall promptly report to the administrative departments of cultural relics of the State Council for handling.

　　(4) The construction land in the buffer zone of the Grand Canal must be incorporated into the local land use master plan and annual plan.

　　Question 46: What development pressures does China’s Grand Canal heritage face?

　　With the rapid economic development in China in recent years, the cities along the route are experiencing rapid urbanization and modernization, which makes the Grand Canal of China face certain pressure of urban and rural construction and water conservancy and shipping construction.

　　One isUrban and rural construction pressureSince the Grand Canal has been a prosperous area of urban development since ancient times, a certain number of buildings have been built along the Canal since the reform and opening up, in the process of rapid economic development and urbanization in China. With the increase in the number of motor vehicles and the need for convenient transportation between cities, some roads and railway bridges across the canal have also been built along the canal. In view of these situations, since 2008, the people’s governments at the provincial and municipal levels along the Grand Canal have organized and published all kinds of conservation plans for the Grand Canal heritage, in which the scope of protection and construction control zones have been delineated, and strict construction approval procedures have been stipulated. The government of the heritage site strictly supervises the construction of the heritage area and buffer zone according to the plan, effectively controlling the building density, height and the construction of traffic facilities.

　　The second isPressure of water conservancy and shipping constructionDue to the continuation of the water conservancy and shipping functions of the Grand Canal in China, more modern water conservancy and shipping facilities have been built one after another to ensure their use functions. These non-traditional facilities have affected the landscape of the heritage to a certain extent, and the local landscape is not harmonious. In order to cope with this pressure, the relevant construction departments have reached a consensus with local governments that in accordance with the Grand Canal Heritage Protection and Management Master Plan (2012-2030), priority will be given to the use of traditional technologies, traditional materials, traditional structures and traditional crafts adopted in various sections of the Grand Canal heritage history in the future, and the appearance, design, materials and entities, uses and functions of water conservancy and shipping facilities will be identified, respected and preserved.

　　Question 47: What is the environmental pressure on the Grand Canal in China? What are the countermeasures?

　　The ecological environment and environmental quality within the scope of China’s grand canal declaration have been protected in accordance with national standards for a long time, and the overall situation is good.Environmental pressure mainly comes from the changes of water environmental quality, air quality and climate.. According to its functions such as water conveyance and flood discharge, the quality of water environment basically meets the Ⅲ ~ ⅴ standards stipulated in the National Quality Standard for Surface Water Environment (GB3838-2002). The air quality in rural areas and built-up areas reached the first-class standard and the second-class standard stipulated in the Environmental Air Quality Standard (GB3095-1996) respectively.The frequent occurrence of extreme weather, especially rainstorm and drought, caused by climate change has aggravated the pressure of flood control and drainage in the Grand Canal in China, and has had a certain impact on the site.

　　China’s Grand Canal heritage protection and management institutions shall, in accordance with relevant protection laws and regulations and the Grand Canal Heritage Protection and Management Master Plan (2012— 2030) implements environmental protection in the chapter of heritage environmental protection planning.It mainly includes: regulating water system, allocating river basin and regional water resources; Protect and repair ecological banks; Improve the environment by wetland construction, water exchange or site protection; Restrict land management and construction within the scope of protection zoning; Strictly control pollutants discharged into water bodies; Strengthen the prevention and control of industrial pollution along the canal; Build urban and rural sewage treatment facilities and centralized garbage collection and treatment facilities, and establish a long-term cleaning system; Scientific monitoring, etc.Flood control planning and comprehensive planning have also been formulated in each basin to cope with the pressure of flood control and drainage brought about by climate change.

　　Question 48: What natural disasters are facing China’s Grand Canal? What countermeasures have been taken?

　　The common risks faced by the Grand Canal in China are mainly floods.

　　In order to cope with the flood disaster, the Ministry of Water Resources of People’s Republic of China (PRC) and the people’s governments of relevant heritage sites have formulated flood control plans at different levels according to the Flood Control Law of People’s Republic of China (PRC) (1998), and detailed flood control schemes have been formulated in the plans. China’s Grand Canal has successively completed flood control projects in its comprehensive management projects since the 1950s.People’s governments at all levels also strictly follow their respective flood control plans to prevent and control flood disasters at three levels: basin, region and city.The concrete measures are mainly embankment treatment and river regulation: the embankment line and the transverse and longitudinal sections of the embankment are designed according to the flood control scheme to strengthen the flood control embankment; In accordance with the requirements of stabilizing the river to make the best use of the flood and prevent ice, bank protection, branch blocking, water diversion, dredging, river widening project and river bend cutting project are implemented for river regulation. In addition to engineering measures, some non-engineering measures have been taken, such as establishing flood forecasting and warning system, strengthening flood area management, formulating flood insurance and emergency measures for exceeding the standard flood. The Grand Canal in China has established an uninterrupted river monitoring, communication and early warning system, and formulated a flood emergency plan. The emergency plan deals with the flood disaster by improving the level of flood forecasting and early warning, increasing flood discharge, and moderately overstocking inland rivers and lakes in the basin. Through the above measures, the effective prevention and control of flood disaster risk in the Grand Canal has been realized.

　　In addition, in view of the fire risk of the buildings in the application elements, in addition to ensuring fire exits, all heritage sites have been equipped with fire prevention equipment, designated responsible persons, and formulated fire safety management regulations and emergency plans. Through these measures, the requirements of minimizing fire risk and reducing disaster losses can be achieved.

　　Question 49: What laws and regulations protect the Grand Canal in China?

　　As a huge heritage in use, the outstanding universal value, authenticity and integrity of China’s Grand Canal are related to multiple attributes, which makes China’s Grand Canal subject to multiple and three-dimensional legal protection.First of all, we must comply with international conventions such as the Convention for the Protection of the World Cultural and Natural Heritage and the Operational Guidelines for the Implementation of the Convention for the Protection of the World Cultural and Natural Heritage, as well as the requirements of national laws and regulations such as the Law on the Protection of Cultural Relics in People’s Republic of China (PRC), the Regulations on the Implementation of the Law on the Protection of Cultural Relics in People’s Republic of China (PRC), the Administrative Measures for the Protection of World Cultural Heritage of the Ministry of Culture, and the Administrative Measures for the Monitoring and Inspection of China World Cultural Heritage of National Cultural Heritage Administration.. Secondly, the water conservancy management department is responsible for the management of the rivers and embankments of the Grand Canal in China. The Grand Canal in China is also protected by the Regulations on the Management of Rivers in People’s Republic of China (PRC), the regulations on the protection and management of rivers and lakes in provinces and cities along the route, the measures for the implementation of river management and the regulations on the management of water conservancy projects. The heritage elements declared by the Grand Canal in China include five historical and cultural blocks and one historical and cultural town in the national historical and cultural cities, and are also protected by the Regulations on the Protection of Famous Historical and Cultural Cities, Towns and Villages. The heritage elements of the grand canal heritage declaration include a national scenic spot — — Jiangsu Shugang Slender West Lake Scenic Area is protected by the Regulations on Scenic Areas promulgated by the State Council. Nansihu Provincial Nature Reserve is also protected by People’s Republic of China (PRC) Environmental Protection Law and other natural resources protection laws and regulations. The Grand Canal is also protected by various special laws and regulations. For example, the departmental regulation "Measures for the Protection and Management of the Grand Canal Heritage" adopted by the Ministry of Culture in 2012, the Joint Agreement on the Protection of the Grand Canal Heritage jointly formulated and signed by the cities along the Grand Canal in September 2012, and the regional "Measures for the Protection of the Grand Canal Heritage" formulated by the provincial and municipal governments along the route.

　　In addition to the law,China’s Grand Canal has a complete protection planning system.Including: China Grand Canal heritage management planning, national protection planning, provincial protection planning, prefecture-level protection planning, important point protection planning and various detailed planning. All stages and levels of planning are connected with each other, and each has its own emphasis. Together, an overall policy of comprehensive protection of the Grand Canal heritage has been constructed, and a comprehensive and instructive protection planning system has been formed.

　　Question 50: What are the management institutions of the Grand Canal in China?

　　As a linear living heritage, the Grand Canal in China has the characteristics of multi-level and multi-sector management. The declared heritage areas and buffer zones shall be managed by local people’s governments at all levels and river basin management agencies according to their jurisdiction and in accordance with laws and administrative regulations. The competent department of cultural relics in the State Council is in charge of the overall protection of the Grand Canal heritage, and cooperates with the competent departments of land, environmental protection, transportation and water conservancy in the State Council to carry out relevant work within their respective responsibilities according to law.The people’s governments of cities along the Grand Canal shall be responsible for the protection of the Grand Canal heritage within their respective administrative areas, and establish corresponding coordination agencies. The departments in charge of cultural relics, land, environmental protection, transportation, water conservancy, construction, planning, tourism and other cities are responsible for the protection of the Grand Canal heritage within their respective functions and duties.

　　The heritage protection of the Grand Canal in China is a cross-industry and multi-field work, involving related institutions and many stakeholders in the fields of cultural relics, transportation, water conservancy, environmental protection, land and construction. To this end, governments at all levels in China have established an effective consultation mechanism to coordinate the major issues of many industries involved in the heritage protection of the Grand Canal in China, clarify the division of responsibilities of relevant departments and regions in the heritage protection of the Grand Canal, and strengthen exchanges and cooperation between different fields. At the national level, an inter-ministerial consultation group for the protection and application of the Grand Canal has been established, and at the local level, a corresponding provincial (municipality directly under the Central Government) and municipal leading group for the protection and application of the Grand Canal (consultation group) has been established. Regular meetings have been held to consider major issues such as draft regulations, planning and key work arrangements for the protection of the Grand Canal heritage, so that these tasks can be coordinated in a timely and effective manner.

　　The people’s governments of cities along the Grand Canal in China have established the Alliance of Cities for the Protection and Heritage Application of the Grand Canal. The city alliance jointly formulated and signed the Joint Agreement on the Protection of the Grand Canal Heritage, which clearly defined the cooperation mechanism of the city alliance and the relevant requirements for the protection of the Grand Canal heritage. If the heritage area crosses administrative boundaries, the local people’s governments at or above the county level adjacent to it will study and solve the cooperation and coordination issues in the protection of the Grand Canal in China through joint meetings of relevant departments and city alliance meetings.

　　After the successful application of the Grand Canal, on September 26th, 2014, 35 cities along the Grand Canal held a meeting in Yangzhou, renaming the Grand Canal Protection and Heritage Application Cities Alliance as the Grand Canal Heritage Protection and Management Cities Alliance. At the same time, the Grand Canal Joint Declaration World Heritage Office was renamed as the Grand Canal Heritage Protection and Management Office, which was unveiled by National Cultural Heritage Administration.

Original Gu Huang Lu Shanghai Mental Health Flying Green Ribbon

"Are you I or E?" This is the latest social opening remarks of young people on the Internet this year. Some friends may ask, what is I? What is e-man? In fact, "I person" comes from "I personality" in MBTI(Myers-Briggs Type Indicator) personality test. "I" personality represents introversion, that is, introverted and introverted person, referred to as social phobia; "E" personality stands for extroversion, that is, extroverted, cheerful and naturally familiar people, referred to as social cattle. The biggest difference between I and E is that I socialize to consume electricity, while E socializes to charge.

For schizophrenics, due to the serious disorder of thinking, perception and emotion, abnormal behavior and social dysfunction caused by the disease, they generally have certain social dysfunction, such as interpersonal skills, social adaptability and learning disabilities. In other words, a schizophrenic often shows a deep "type I personality" when facing social interaction.

What is music therapy? What kind of "magic power" does music have to improve the "autistic" symptoms of deep "type I personality"? Today, let’s discuss the influence of group music therapy on interpersonal relationship in the social function of schizophrenics!

01

Schizophrenia-the gathering place of "I" type people

Schizophrenia is a kind of serious mental disorder, which mostly occurs in young adults. The onset is often slow, and the clinical manifestations are obstacles in thinking, emotion, behavior and uncoordinated mental activities. The impairment of social ability in cognitive function of schizophrenic patients has been confirmed by a large number of studies.

Specifically, one of the manifestations of impaired social function of schizophrenic patients is the lack of social skills caused by various reasons, such as dull eyes when talking to people, dodging eyes, caring about others and so on. For example, neighbor Xiao Wang is a schizophrenic. One day when you meet each other in the narrow corridor, you may ask, "I haven’t seen you very much recently. What are you busy with?" Xiao Wang can dodge his eyes and hesitate for a long time before answering "hmm … OK". According to the survey, more than 50% patients with schizophrenia in stable stage will continue to show social skills defects characterized by their inability to talk actively, expressing their inner feelings and being difficult to solve problems, just like Xiao Wang.

Is Xiao Wang’s "social disorder" because he didn’t take his medicine on time? Of course not! Antipsychotic drugs can effectively alleviate mental symptoms, but have no effect on improving social skills defects. At this time, we need to invite our protagonist today-"Music Therapy".

02

"Magic Power" from Melody —— Music Therapy

Music therapy is a popular form of music activity. It involves physical functions, such as participating in vocal organs and respiratory system, as well as psychological functions and emotional expression. It is reported that group music therapy can improve the quality of life, mental health and neurochemical activities (such as dopamine and oxytocin levels) of the elderly.

From the perspective of clinical application, music therapy has long been used as a part of the combined treatment of various neuropsychiatric diseases, and has been widely used in patients with emotional disorders, anxiety disorders, psychotic disorders and cognitive disorders.

From the perspective of neuroimaging, it also provides further evidence for the brain structure and neural circuits corresponding to music processing. Personal handling of musical stimuli is usually related to the emotional circuit of the brain. This effect can be observed in insula, cortex (CC), prefrontal cortex (PFC), hippocampus, amygdala and hypothalamus (23). In addition, music can cause changes in the levels of important neuromodulators, such as dopamine, endorphins, endogenous cannabinoids and nitric oxide.

03

Effect of Music Therapy on Social Function of Schizophrenia Patients

One of the reasons for the impairment of social function of schizophrenic patients is cognitive impairment. Cognitive function is impaired in a wide range of forms, including obstacles in decision-making, abstract thinking, information processing, verbal memory expression, visual memory understanding, etc., among which the most serious ones are information transmission, attention, learning and memory. Imagine that when you chat with Xiao Wang, Xiao Wang’s answer is always that the donkey’s lips are not right for the horse’s mouth, or that his mind is rambling. Often, before you finish a word, Xiao Wang deserted …….. As time goes by, the boat of friendship will drift further and further.

For people with severe mental disorders like Xiao Wang, music therapy often relies on a mixture of active and receptive skills, and improvisation and the language of music interaction are often the core. Music therapists who work with these people in clinical practice usually receive systematic training, and music therapy is usually provided in an individual or group environment, and a treatment cycle is usually from January to March. At the same time, it is crucial that Xiao Wang actively participate in music therapy is the key to success.

Clinical reports show that music therapy has unique qualities of motivation, relationship building and emotional expression, and the key is to help those who can’t accurately express themselves and emotions. Music interaction in music therapy may also support the reconstruction of music resources and abilities that affect patients’ daily life. From the patient’s point of view, this is an important factor for music therapy to improve the quality of life.

04

Clinical application of music therapy

Clinically, music therapy is usually divided into three stages, namely:

(1) The first stage: receptive music therapy, which emphasizes listening to music and various physiological and psychological experiences caused by listening to music. The specific contents include song discussion, music synchronization, music memory, music imagination, music biofeedback and music relaxation training. For example, through the observation of music therapists, Xiao Wang has a lot of resonance with melodious piano music and will have certain emotional reactions. So the music therapist invited Xiao Wang to listen to the piano music with her, and asked Xiao Wang to choose the piece that best described her mood from several piano music and share it with her.

(2) The second stage: Re-creative music therapy, which emphasizes that the treated person not only listens, but also participates in various music activities in person. The specific methods usually include singing and playing, learning music skills, etc. Through this artistic carrier, individuals in the group are encouraged to express themselves. After several classes, Xiao Wang pointed out the African drum as "his instrument" among the many percussion instruments prepared by the music therapist. Xiao Wang said that because he felt that when he hit the drum surface, the touch of the leather surface bounced like his ups and downs when he was sick. Beating rhythmically made him feel that his repeated illness was controllable and he felt relaxed and safe.

(3) The third stage: impromptu music therapy, in which patients improvise music at will on specific musical instruments to achieve the purpose of treatment. In the last class, the music therapist asked each patient in the group to play a song for themselves with their own musical instrument. Xiao Wang hit a happy birthday with the African drum. He said that after a period of music therapy, he could feel that the "monster" in his mind had stabilized a lot. Today is the end of the course and the day of his rebirth.

　　Studies have shown that long-term intake of waste oil will cause obvious harm to human body, such as developmental disorders, enteritis, hepatomegaly, heart and kidney enlargement and fatty liver. Aflatoxin, one of the main hazards in gutter oil, is a strong carcinogen, and its toxicity is 100 times that of arsenic. Another question is ethical. Can you eat the oil that others have eaten, which goes bad in the sewer and is fished out again?
　　So, is there a simple way to identify gutter oil? We might as well listen to what food science experts and insiders say.
one
There is no good way to scientifically identify waste oil at present.
　　In an era of paying attention to food safety, the ideal state is that when you go to a restaurant, you take out a test paper and dip it in the dish. After a while, you take it out and compare it with the spectrum table, and then shout, "Boss, change the oil!"
　　However, the reality is that up to now, scientists have not found an ideal means to detect and identify gutter oil.
　　"Oil mixed with oil, fairy sorrow, fairy is difficult to separate it. Waste cooking oil has a history of more than 20 years. Even today, we can still see waste cooking oil in rural markets and urban-rural junction markets, and we also feel that it has entered the dining hall. If calculated by tonnage, there should be millions of tons of waste oil digested every year. I am very embarrassed. We can’t find a very effective technical means to identify it. This oil is gutter oil, and this oil is not gutter oil. " When attending a CCTV program, Hu Xiaosong, vice president of the College of Food Science and Nutritional Engineering of China Agricultural University, once said this.
　　Hu Xiaosong pointed out that the current detection methods have not overcome this technology and cannot scientifically distinguish the quality of oil, but the Ministry of Science and Technology has set up a special project for this matter, and I believe that it will be possible to distinguish the quality of oil by scientific means in the near future.

Traditional detection methods have certain limitations.
　　In the view of scientific researchers, the difficulty in treating gutter oil lies in that it is difficult to distinguish gutter oil from ordinary oil only from appearance and sense after refining processes such as washing, distillation, decoloration and deodorization. Illegal traders will also mix waste oil into edible oil, and if the content is small, it is even more difficult to detect.
　　He Dongping, a professor at the School of Food Science and Engineering of Wuhan Institute of Technology, has been engaged in the research of gutter oil for many years. In He Dongping’s view, the traditional detection methods only grasp a certain characteristic of gutter oil, and no method can effectively detect gutter oil from different sources at the same time, which sometimes leads to a large detection error and more possibility of misjudgment.
　　Wang Le, a graduate student of Wuhan Institute of Technology, once developed a blue test paper. With the increasing proportion of waste oil, the blue test paper will show yellow-green, light yellow and bright yellow. This is based on the "accumulation" of oil to detect the purity of oil, but this method is also limited by the proportion of waste oil added.
　　On the Internet, you can find a company specializing in the production of "Quick Detection Kit for Waste Oil", but from the instructions provided by the company, "for some unpurified oils (such as sesame oil, pepper oil, etc.) and oils with other ingredients (such as Chili oil), this method is easy to produce false positives".

Identify the waste oil refrigerator?
　　Senior chef Feng Peng, who once worked as a chef and executive in many big restaurants in Beijing, said that under normal circumstances, gutter oil and ordinary oil can’t be distinguished, and it is inevitable to be fooled when purchasing. He can only judge by practice: restaurants usually need to oil before cooking. In this "lubricating oil" process, good oil can be used seven or eight times repeatedly, while waste oil will become sticky and have a spicy taste after being used for up to three times.
　　"In addition, when the outdoor temperature is low, waste oil will solidify like palm oil, so people often use waste oil to pretend to be palm oil." Feng Peng said that gutter oil can be identified in winter and can be tested in the refrigerator in summer. Some media think that gutter oil has a taste and can be smelled out. In addition, it contains a lot of water, and the pot will explode. Feng Peng thinks these are nonsense, because water can’t be mixed into oil at all, and gutter oil has no odor.

How should we identify waste oil?
　　Take a look. Look at the transparency, pure vegetable oil is transparent, and the transparency will decrease due to the mixing of alkali grease, wax and impurities in the production process; Look at the color, pure oil is colorless, and the oil will be colored because the pigment in the oil is dissolved in the oil in the production process; Look at the sediment, its main component is impurities.
　　Second smell. Each oil has its own unique smell. You can drop a drop or two of oil on your palm, rub your hands together, and smell it carefully when you are hot. Oil with odor indicates that there is a problem with the quality, and it is likely to be waste oil with odor; If there is a smell of mineral oil, you can’t buy it.
　　Three tastes. Take a drop of oil with chopsticks and taste it carefully. The oil with sour taste is unqualified, the oil with bitter taste has been rancid, and the oil with peculiar smell may be waste oil.
　　Listen. Take one or two drops of oil from the bottom of the oil layer, coat it on flammable paper, light it and listen to its sound. The products with normal combustion and no noise are qualified products; If the combustion is abnormal and makes a "squeaky" sound, the water content exceeds the standard and it is an unqualified product; The "crack" explosion during combustion indicates that the water content of the oil is seriously exceeding the standard, and it may be adulterated products, so it is absolutely impossible to buy.
　　Five questions. Ask the merchant about the purchase channel, ask for the purchase invoice or check the sampling test report of the local food hygiene supervision department if necessary. (Comprehensive by this newspaper)

　　If the empire is understood as a conquest system composed of suzerain and conquered areas, then China has never been an empire. China established a unified centralized country in the Qin Dynasty. Although Ying Zheng claimed to be the "emperor", this unified country was not an empire. China has been the vertical rule of the county system since the Qin Dynasty. All officials are appointed by the imperial court, and there is no entrusted management. As Han Feizi said, China’s ancient state structure is "everything is in the four directions, and it should be in the central government, and the saints should insist on it, and the four directions should be effective". After Qin destroyed the six countries, the whole country was divided into thirty-six counties. From then on, the central government of China was not composed of localities, but was divided by the central government. The central government precedes the local government in logic and time. All the ruling power of the country comes from the central government, and the local government does not have any inherent power. The place is the agency of the central government, and the central government is "like an arm, like an armband" to the place. Therefore, there has never been an empire in the history of China, and the concept of empire has never appeared in the language and writing of China.

　　At the same time, the ancient Central Plains civilization in China also promoted the homogenization within the unified country. The ancient Central Plains civilization in China is a powerful cultural soft power to attract and integrate the surrounding ethnic groups. Mencius called it "changing foreigners with summer". After the Han Dynasty, people often use Sinicization to explain the process of homogenization of unified China by Central Plains civilization. This is also fundamentally different from the empire where various heterogeneous civilizations coexist.

　　如上所述，在西方政治话语和学术语言中，帝国是一个由中央地带与从属地带共同组成的征服体系。如果把中国古代王朝的强盛时期称之为帝国，就意味着中国在古代曾经是一个征服体系。西方一些学者常常把中国的清王朝称之为帝国，认为清王朝的疆域是一个征服了多个领土、多个民族的多层次体系，疆域内各个民族、各个地区都是帝国的板块，只是暂时被清王朝用武力所统治。按照这种观点，清王朝崩溃以后，帝国的一些板块就应当独立出去，就像当年沙皇俄国崩溃以后，各个板块独立出去一样。所以，如果承认清王朝是帝国，就意味着中国的边疆是被清王朝征服的，清王朝一旦崩溃，这些由不同种族构成的边疆地区就应当独立出去。这也是为什么一些西方人支持中国的西藏、新疆独立的原因之一。所以，中国在清代不是一个帝国，这不仅是一个理论问题，而且也是一个重要的现实问题。

　　In China academic circles, some scholars have seriously discussed the concept of empire. But even among some scholars who try to clarify the concept of empire, there are still some vague understandings. For example, some scholars denied that there had been an empire in China since the Qin and Han Dynasties, but they still understood the Zhou Dynasty before the Qin Dynasty as an empire, on the grounds that the Zhou Dynasty’s local rule was not direct, but indirect, which was similar to the western empire. In fact, this is also an inaccurate understanding of the political structure of the Zhou Dynasty. There is no doubt that the centralized political structure of the Zhou Dynasty is fundamentally different from that of the Qin and Han Dynasties. But this difference is not the difference between an empire and a centralized dynasty, but the difference between a feudal system and centralization of authority.

　　The Zhou Dynasty in history was not a conquest system, but a enfeoffment system formed by the supreme ruler Zhou Tianzi. Within this system, more than 70 feudal vassal States were not conquered and established by the Zhou Dynasty, but were enfeoffed by the Zhou Dynasty according to the merits of being close to each other and defeating the Shang Dynasty. The people of these vassal States were all Chinese. The national political structure of China in the Zhou Dynasty was similar to the feudal system in the Middle Ages in Western Europe, but it was fundamentally different from western empires, such as Alexandria and Rome.

　　What needs to be clarified is that in history, China’s national structure seems to be similar to that of western empires in some aspects. In the history after Qin and Han Dynasties, China’s imperial court sometimes ruled the border areas loosely, and sometimes it ruled indirectly instead of directly. For example, the chieftain system in the remote areas of China once existed widely, which was called "Jimi system" in ancient times. If ancient China was not an empire, how can we understand that this national structure is similar to the empire?

　　Personally, I think the most fundamental difference is that China’s idea of unification is totally incompatible with the idea of empire. China’s national construction has a set of political ideas, political theories and a political belief, which is China’s idea of great unification. This idea mainly comes from Legalists and Confucianists, although the two most influential schools in China often argue with each other. China’s system since Qin Dynasty is Confucianism, and the basic framework and system of the country are based on the principle of Legalism, which is embodied in the centralized county system, which is called "the political system of Qin Dynasty is practiced in all generations"; Confucianism, on the other hand, provides the society with general ethics and moral norms, maintains the relationship between people, and also regulates the relationship between monarch and minister.

　　There is indeed a real problem here. In ancient times, it was really difficult for the central government to implement unified vertical rule in a huge territory. Due to the low productivity in ancient times, such as the level of material development, traffic roads and tools are very backward. This has indeed caused great difficulties to the unified national governance. In the political centers of ancient China, such as Chang ‘an, Luoyang and Peking, it was difficult to implement vertical rule in the border areas. It takes several months to go to Beijing from Guizhou, Yunnan, and vertical management is of course very difficult. However, after Qin and Han Dynasties, unification has become the consensus of Confucianism and Legalism. So from the Qin and Han dynasties, a new system was used — — To manage the border areas by the system of detention. The system of detention is an expedient measure. When the central government is unable to reach the local level and has no way to directly rule, it can temporarily give the place of detention autonomy, similar to the empire’s rule over the conquered place. The system of detention is relatively loose, such as the toast system in the ancient frontier areas of China. You can manage yourself by paying tribute and being loyal to the court.

　　So, does this mean that the detention system is the same as imperial rule? In fact, the difference is very big. China’s thought of unification has been deeply rooted in people’s hearts since Qin and Han Dynasties. Due to the constraints of realistic conditions, the central government can give local governments a lot of autonomy at some time, but these autonomy rights are by no means inherent in local governments. The central government can grant local governments a great deal of autonomy, but because the source of law lies in the central government, the central government has the right to take it back when conditions are ripe. This is the change of soil into the stream in the history of China. This is not the same as the empire. China’s thought of unification has penetrated into the marrow of rulers and literati, and is the core of China’s political culture.

　　Therefore, for more than two thousand years, China’s detention system is a supplement to the centralized unified system, and the central government has unified all the territories through a set of very complicated and elaborate designs. Sometimes, ancient China looks like an empire on the surface, and even some frontier areas have greater autonomy than the subordinate areas of the empire. However, in China, all the power in the border areas is granted by the central authorities, not the local authorities, and the local authorities have no inherent power. That is to say, the unified county system has never been a conquest system outside the country, although it can’t fail to reach the surrounding boundaries for a while. For the central court, all the border areas have been brought into the unified national framework.

　　Therefore, from the formal point of view, there are essential differences between the system of imprisonment and the imperial system under the framework of China’s ancient unification. I think it’s necessary to distinguish between the empire and the fetter system in our history. If we don’t make a distinction, it will cause great confusion and threaten the state structure of China now. Of course, the comparative study of the captive system and the imperial system still needs a lot of work, which requires a lot of detailed analysis.
