Yuwen Tai
Yuwen Yong was born in 543, as the fourth son of the Western Wei paramount general Yuwen Tai. His mother was Yuwen Tai's concubine Lady Chinu. He was born at Yuwen Tai's then-headquarters at Tong Province (同州, roughly modern Weinan, Shaanxi). He was considered filially pious, respectful, and intelligent in his youth. In 554, Emperor Fei of Western Wei created him the Duke of Fucheng.
