The Fang family comes from the Tao Tang family and is a descendant of Yao. Yao had a son who was initially enshrined in Danshui, and people called him Danzhu. Because he was incapable of governing the world, Yao gave up his throne to Shun. Shun also granted Danzhu to Fang (now Suiping County, Henan Province), established the Fang Kingdom, and made him a Marquis of Fang. Danzhu's son Ling took his father's fiefdom as his surname and was called Fangling, and later became Fang. A prominent family with the surname Fang lived in Qinghe (today's east of Qinghe County, Hebei Province). Yao's son Danzhu was granted the title of Marquis of Fangyi by Shun. His son Ling took his father's fiefdom as his surname, and his descendant Sun Ya was the prefect of Qinghe. He first lived in Yan. Today, the surname of Fang is Qinghe County. This is the original name.
