Are there any property companies in Beijing that undertake old residential areas? Please tell me more, and it should be a qualified formal company.

There are property companies in Beijing to take over the old residential areas, but generally the original property companies shovel over to take over the second-hand residential areas. They will also make corresponding budgets according to the current situation of the residential areas, what kind of services they will provide to the residential areas, and sign service contracts with the owners' committees. Community management and services like this had better be free! !
