A house purchased in the name of buying a house before marriage, if it is purchased in full, should be regarded as a gift to the woman, and the house belongs to the woman's personal property. For example, if you buy a house with a loan before marriage, and the woman's name is indicated on the real estate license, if you repay the loan together after marriage, the joint repayment part and the value-added part of the house can be regarded as the joint property of husband and wife.

The Supreme People's Court's Interpretation on the Application of Marriage and Family in the Civil Code of People's Republic of China (PRC) (I)

Article 78 If the husband and wife sign a contract for the sale of real estate before marriage, pay the down payment with personal property and borrow money from the bank, and repay the loan with the joint property of the husband and wife after marriage, and the real estate is registered in the name of the down payment payer, the real estate shall be handled by both parties through agreement at the time of divorce. If no agreement can be reached in accordance with the provisions of the preceding paragraph, the people's court may rule that the real estate belongs to the registrant and the outstanding loan is the personal debt of the registrant. At the time of divorce, according to the principle stipulated in the first paragraph of Article 1087 of the Civil Code, the party that handles the registration of real estate shall compensate the other party for the money paid by both parties after marriage and the corresponding value-added part of the property.
