Local people's congresses at all levels handle local affairs and make scientific decisions on the development path. The system of people's congresses in China fully guarantees the realization of people's right to be masters of their own affairs. As China has a large population, it is impossible for people to directly participate in various meetings. To fully reflect the true thoughts of the people, only by electing their own representatives to participate in the National Congress, which is the National People's Congress.
