Wuhan office building property fee collection standard. Who can introduce me?

Implement the current Wuhan property management regulations (20111165438), and deliver according to 70% and annual non-occupancy regulations. The original text is as follows: Article 12; Property service fees incurred before the house is delivered for use (including the current month) shall be borne by the development and construction unit. The property service fee generated after the house is delivered for use shall be borne by the owner, but if there is no occupancy within one year after the house is delivered, the owner shall bear 70% of the property service fee during the vacant period.
