Xie Jin has three sons and one daughter. Director Xie is addicted to alcohol, so his daughter and two sons are disabled. Except that the eldest son Xie Yan is completely normal and talented, the slight disability of the eldest daughter Xie Qingqing does not affect her life, and the second son Xie Jianqing and the third son Xie Jiaqing cannot take care of themselves. Except Zheng Yang (nicknamed "Yang Yang"), the eldest son missed a love when he was young and never got married. Sun Tzu is the only third generation of director Xie Jin.
