After the property or the unit that sells the house is collected, it will be deposited in the local development bank (generally the Construction Bank) together with the maintenance funds that the developer should bear, which will be supervised by the government real estate department and the account will be owned by the owner. Under normal circumstances, the maintenance fund shall not be used before the establishment of the owners' meeting, but after the establishment of the owners' meeting, it will be used for the overhaul of public parts, subject to the consent of more than half of the relevant owners. The allocation of maintenance funds can be based on floors, buildings and regions.
