Yu Bing

Yu Bing (birth and death dates unknown), courtesy name Shiwen, was an official of the Western Jin dynasty. He previously served in the state of Eastern Wu during the Three Kingdoms period.

Life
Yu Bing was the eighth son of Yu Fan, an official who served under Wu's founding emperor Sun Quan and under Sun Quan's predecessor Sun Ce. His ancestral home was in Yuyao county (餘姚縣), Kuaiji commandery (會稽郡), which is in present-day Yuyao, Ningbo, Zhejiang. He harboured extraordinary ambitions when he was young. When he grew up, he served in Wu as a "Gentleman of the Yellow Gate" (黃門郎) and was promoted to "Imperial Secretary and Palace Attendant" (尚書侍中) later.

In 280, when forces of the Jin dynasty invaded Wu, the Wu imperial court granted authority to Yu Bing to supervise military affairs in Wuchang (武昌; present-day Ezhou, Hubei). However, Yu Bing returned his official seal and authority to the Wu court and then surrendered to Jin. He was appointed as the Administrator (太守) of Jiyin commandery (濟陰郡; around present-day Dingtao County, Heze, Shandong) by the Jin government. He became famous for upholding justice and helping the poor while he held office.

Family
Yu Bing had 10 brothers. Among them, the notable ones were his fourth brother Yu Si, fifth brother Yu Zhong, and sixth brother Yu Song.
