What is the responsibility of the neighborhood Committee in a community without property? Should I try to build a neighborhood Committee privately?

I estimate that the neighborhood Committee may collect management fees from it every month. Neighborhood committees have four functions, namely management, service, supervision and education. The relevant person in charge of the neighborhood committee should manage and supervise it, so as to standardize its operation, and it is forbidden to occupy roads and disturb the normal life order of residents. If you go your own way, you should cooperate with the relevant units to suspend business for rectification until it is demolished.
