Which department should I consult if I want to consult the time limit of the real estate license of the new community; You can go to the real estate trading center for consultation. . .

Because the real estate trading center is an authoritative department, all those who handle the real estate license can only go to the real estate trading center to handle it.

The information consulted by other departments and institutions is not as accurate as that of the real estate trading center.
