In 581, Yang Jian had Emperor Xuan's young son Emperor Jing yield the throne to him, ending Northern Zhou and starting Sui Dynasty as its Emperor Wen. Yuwen Shu served as a general for Sui. In winter 588, when Emperor Wen launched a major attack on rival Chen Dynasty, Yuwen Shu participated in the campaign, and after the generals Han Qinhu (韓擒虎) and Heruo Bi (賀若弼) crossed the Yangtze River to attack the Chen capital Jiankang, Yuwen advanced to the nearby fortress of Shitou to aid Han and Heruo. After Heruo and Han captured Jiankang and the Chen emperor Chen Shubao, the Chen generals Xiao Huan (蕭瓛) and Xiao Yan (蕭巖) were holding out in modern Zhejiang. Yuwen was sent, along with Yan Rong (燕榮), to attack Xiao Huan and Xiao Yan, and he defeated Xiao Huan and forced Xiao Yan to surrender. After the completion of the campaign, in recognition of his contributions, Emperor Wen gave his son Yuwen Huaji a mid-level governmental post, while making Yuwen Shu himself the commandant at An Province (安州, roughly modern Xiaogan, Hubei).
