简介：Su Fang and his family of three live in Xiejiazhuang, so they don't need to go back with Su Can and his family. Su Chengfang is alone. He usually has his own house in Qingshi Lane, Old Street, and there is no need to live in Su Can's house. Besides, Su Can's home is not very big, so it would be very crowded if there were so many people living there.
