The origin of Fang's surname

In ancient times, because of Dayu's meritorious service in water control, Shun passed on the throne to him. When Dayu was in charge of water conservancy, he appointed Dani, a son of Emperor Yao, as the leader of (now suiping county, Henan). Dani was also knighted and marquis, so he was also called Fang Houyi. Fang's son is called Fang Ling, and all the descendants of Fang Ling take the fief as their surname, and the surname is Fang from generation to generation. During the Jin Dynasty, Fang Gan was an envoy sent by the imperial court to the northern minorities. Later, when the Central Plains was in war, Fang Gan settled in the northern nomadic people and changed his surname. It was not until the Southern and Northern Dynasties that they moved back to the Central Plains and restored the surname room. Fang's ancestors also had right-hand men, such as Emperor Taizong, who served as prime minister for fifteen years and managed the country well. The court named him Liang Guogong. He is far-sighted, regards state affairs as family affairs, worries day and night, and does it himself.
