Very general, it is said that the first-class property is not ideal in many aspects, and it is understandable that the new residential property is slowly improving, but many small problems are too worrying. It is understandable that there was no heating when I moved in last year. It's almost heating time this year, and the heating seems to be retreating. It is really chilling that the government has stipulated the annual heating time. Such a large property, a first-class property, will not solve the heating problem in advance? It should be that property and real estate need to do heating measures and follow-up services in advance.
