Yuwen Tai
In 553, during the reign of Emperor Wen's son Emperor Fei, Wei was made the governor of the capital region, Yong Province (雍州, roughly modern Xi'an, Shaanxi). In 554, Wei participated in the campaign commanded by Yu Jin (于謹) against Liang Dynasty, which eventually captured its capital Jiangling and its emperor Emperor Yuan. (Western Wei eventually put the Liang emperor to death around the new year 555.) After this campaign, Wei's title was changed to Duke of Rang, and as at the time, Yuwen Tai was choosing prominent Han generals to have their names changed to Xianbei names, Wei's name was changed to Yuwen, probably as a sign of respect and endearment on Yuwen Tai's part. In 556, when Yuwen Tai was carrying out a tour of the northern provinces, he returned Wei to the responsibility of defending Yubi.
