Zhang Jun (general) Zhang Jun (: "Zhāng Jùn" , 1086–1154), was a Chinese general and official who fought during the Jin–Song Wars. His battle with Jurchen commander Wuzhu at Mingzhou near the temporary Song capital of Hangzhou briefly halted the Jin advance, giving the Song Emperor Gaozong the chance to flee the city by ship. Soon after, his army suppressed rebellions and banditry in the south alongside the generals Yue Fei, Han Shizhong, Yang Qizhong, and others. Emperor Gaozong diminished the power of the military by moving Yue, Han, and Zhang to civilian positions in 1141. A year later, the Song finished negotiating a peace treaty with the Jin.
