Changshu Xiaoshengchu took the house book a few months ago.

I went to school in September, 2022, and began to collect information in May 1, and got the room book at the latest on April 30th.

Fangben is the abbreviation of house property right certificate. The property has People's Republic of China (PRC) Property Ownership Certificate and XX Local Property Ownership Certificate. It is an effective legal proof of individual housing property rights. Orientation, structure, area, number of households on the same floor, plot, room plan and other information. It's all in the room book.
