The Cais are said to be the descendants of the 5th son of King Wen of Zhou, Ji Du. The Cai descendants have undertaken two major migrations. During the Huang Chao Rebellion (AD 875) at the end of the Tang Dynasty (AD 618-907), the Cai clan migrated to Guangdong and Fujian provinces. Another migration occurred when the Ming Dynasty loyalist Koxinga moved military officials surnamed Cai and their families to Taiwan in the 17th century. As a result, the surname is far more common in these areas and in areas settled by their descendants (e.g., Southeast Asia) than in other parts of China.
“蔡”行据说是周文王的第五儿子子度的后裔。因子度之子胡被封于蔡，因此他的后人就改姓为“蔡”。蔡后裔已经进行了两次重大的迁移。一是在黄巢起义（公元875 ）（唐朝晚期），蔡氏族迁移到广东，福建等省。另一个迁移发生在17世纪时，明朝郑成功将姓蔡的军官和他们的家人移居到台湾。这样一来，蔡姓在他们的后裔定居地区更为常见（如东南亚）。
