His conquests significantly increased his brother’s power and his death led to complacency in Zhang Shicheng’s court.
Shicheng’s rebellion would spread quickly until it was nearly destroyed by Yuan general Toqto’a in Gaoyou.
These conquests strengthened Zhang Shicheng’s regime but also brought him into conflict with Zhu Yuanzhang, the future founder of the Ming Dynasty.
Zhu tried to use him as a bargaining chip to obtain favorable terms with Zhang Shicheng, but Shide sent his brother a letter telling him not to yield and, if necessary, to instead surrender to the Yuan Dynasty.
From then on, Shicheng took a passive stance to governance, evidenced by his surrender to the Yuan Dynasty in late 1357.
