We are Baogang Building in Longfeng Street, Haizhu District, Guangzhou. Many buildings with unclear property rights (including underground parking lots) have been charged by property management for a long time. It is difficult to set up an industry committee in 2012 and implement self-management. After one and a half years of self-management, the official seal and account books were collected by Longfeng Street. With a property management, the owner continued to be encroached on by the property management, and the owner kept complaining about Haizhu District. The district replied that the street had been held accountable for the matter, but the matter of Baogang Building has not been corrected yet.
