Second, regional autonomy should be practiced in areas where ethnic minorities live in compact communities, and all ethnic autonomous areas are inseparable parts of the people and the country of China. Third, the division of functions and powers between central and local state organs follows the principle of giving full play to local initiative and enthusiasm under the unified leadership of the central authorities. Fourth, the National People's Congress approved the establishment of provincial-level places, the State Council approved the division of provincial-level places and approved the establishment and division of places below the provincial level, and the National People's Congress decided on the establishment and system of special administrative regions. Fifth, the people's congresses of provinces and municipalities directly under the Central Government and their standing committees may formulate local regulations on the premise that different constitutions, laws and administrative regulations are inconsistent, but they must be reported to the NPC Standing Committee for the record; The people's congresses of the autonomous regions have the right to formulate autonomous regulations and separate regulations, which will take effect after being approved by the NPC Standing Committee. Sixth, local people's governments at all levels are responsible and report their work to the people's congresses at the corresponding levels and the state administrative organs at the next higher level. The State Council leads the work of local administrative organs at all levels, and local people's governments at all levels obey the State Council.
