How many editions of Beijing Property Management have there been so far?

Up to now, there are not many versions of Beijing property management, because property management is a comprehensive service, not a software or technical product. Property management includes the maintenance, maintenance, security and cleaning of buildings and their facilities. It has nothing to do with time, and it will not release multiple versions like software. The goal of property management is to provide a safe, comfortable and convenient living or working environment to meet the needs of owners or tenants. Therefore, property management does not involve the concept of version, but is constantly optimized and improved according to the actual situation.
