The famous grandson of Hu, the son of Dugong, the nephew of Hu, the second monarch of Cai, a vassal state of the Western Zhou Dynasty, also known as Cai Zhonghu, was Cai's second ancestor. In the early years of Zhou Chengwang, Cai Shudu, Xian and Huo Shuchu were dissatisfied with the regency and jointly launched the "Three Prisons Rebellion". After the Zhou Gongdan Rebellion, Cai Shu was exiled. Cai Zhong was promoted by Zhou Gongdan to help his son, Lu Gong Bo Qin, because he knew his father's mistakes and obeyed his moral training. Because of Cai Zhongfu's outstanding achievements, Zhou Gongdan renewed Cai Zhong's Cai Guo national seal to show his respect for Cai Shu. Cai Zhong Cemetery was built in Caihou Road, Shangcai County, a provincial key cultural relics protection unit.
