How can I return something if I have a real estate license to prove family planning and social security?

If you buy a house in a residential area, you need to transfer two certificates and handle them separately. First, transfer the real estate license. Only after the transfer of real estate license is completed can the land certificate be transferred. It should be collected twice, and the real estate and land should be collected separately. Buyers need to provide, ID card, household registration book and marriage certificate. Both certificates are available, ranging from more than 20 days to two months.
