After the death of Su Jun's other brother, Su Shuo (蘇碩), Han Huang and the rebels became worried as loyalist forces approached Shitou. Han Huang and the others decided to lead Su Yi and his remaining forces to Qu'a (曲阿, in present-day Suzhou, Jiangsu) to join Zhang Jian (張健). However, the passes and gates in Shitou were so narrow that the rebels began stampeding on each other, leaving thousands dead. It also gave loyalist troops ample time to catch up with the rebels. They managed to capture and execute Su Yi, but Han Huang and the others were able to escape, changing their destination to Guzhang.
