Lujiang 庐江Ancestral Commandery
The Legacy of Lujiang: Han and He, One Kin
Main lineage: Traditionally from the Han clan of the Ji surname. After Qin destroyed Han, the Han descendants fled and changed their name to He—the two characters sounded alike in antiquity.
A clan of many sources: Other branches changed from ethnic-minority surnames.
Root point: Lujiang, Anhui.
▸ Internal migration: The clan arose between the Yangtze and Huai rivers; the Wei–Jin migration went south; the Tang and Song brought it into Fujian and Guangdong; the Ming and Qing spread it nationwide.
▸ Overseas branches: Hes of southern Fujian and Chaoshan went in great numbers to the Nanyang.
