Because according to the Interim Measures of the Ministry of Housing and Urban-Rural Development (J.J.F. [2006] No.244) and other relevant regulations, the owner of the house can hold his identity certificate, indicate the number of the house or the ownership certificate and the inquiry matters, and go to the housing archives management department of the residential area where the house is located to inquire about the real estate information under his name. This information can't be found on the Internet, because house registration is a special system.
So you can go directly to the housing archives management department of your community and inquire about the real estate information under my name.
