Understanding of the System of Regional National Autonomy Regional ethnic autonomy is a basic policy to solve ethnic problems and a basic political system in China. It forms three forms of socialist democratic political system in China, namely, the system of people's congresses and the system of multi-party cooperation.According to the requirements of the new curriculum standard, students should understand that the system is suitable for the national conditions and has significant advantages. They are prepared to assume the historical responsibility of upholding and improving the system. The national distribution characteristics of a unified multi-ethnic country and "large mixed and small cohabitation" determine that China can neither implement "national autonomy" based on ethnic groups alone nor "local autonomy" based on regions alone, but combine national autonomy with regional autonomy to implement regional national autonomy.Due to the multi-level regional autonomy of ethnic minorities, not only can one ethnic minority exercise autonomy in another place, but also can join forces with other ethnic minorities in many places to implement autonomy at different levels.In addition, ethnic townships have been established as a supplementary form to ensure that ethnic minorities enjoy the right to be the masters of their own affairs and to manage the internal affairs of their own ethnic autonomous areas.The implementation of this system has a solid social and political foundation. China's ethnic policy originated from the former Soviet Union - - giving preferential treatment to ethnic minorities.There is a column in all the tables: nationality.Therefore, it deepens people's national consciousness and weakens the Chinese consciousness.The stronger the national consciousness, the greater the possibility of national division. The former Soviet Union is a lesson.
