got any info you can share? All I've found is about the "neighborhood committees" that are the lowest level of organization in China

The responsibilities of Neighborhood Committees are:

-To instruct local residents about the Constitution, policies and laws,

-To collect the subscription of the apartment building and building site, and to mark the documents,

-To help supporting the legitimate rights of the residents,

-To protect public property,

-To organize community events and entertainment,

-Peacemaking on low-level disagreements,

-To help public safety,

-To govern hygiene in common areas,

-Care of the elderly and handicapped, education of young and the improvement of social security,

-To bring the needs of suggestions of citizens to the attention of the government.
