Does the old residential area in Chongqing also have to implement the one-fee system for property fees?

I have to. The biggest feature of the new regulations is the "one-fee system", that is, changing the collection method of basic property fees, shared electricity fees and elevator fees in the original residential quarters and implementing "three fees in one". Old residential areas in Chongqing must also implement the "one fee system" for property fees. Property management refers to the maintenance, conservation and management of houses, supporting facilities and related sites by property management enterprises according to property service contracts.
