He served in the Imperial Painting Academy (廷畫院) during the reign of the Kangxi Emperor.[2] His skills were valued by many noted contemporaries, including Chen Tingjing, Xu Qianxue, and Gao Shiqi, all of whom ordered portraits and other paintings from him.[3] Yu was taught by Lan Ying, and painted landscapes, human figures, and bird-and-flower paintings. He retired from office in 1690 and settled in Taihu, Jiangsu.
