Qin Zongquan
Later in the year, Qin Zongquan, a former Tang military governor who had rebelled and claimed the title of emperor himself, sent his brother Qin Zongyan () to attack Jingnan Circuit. Qin Zongyan put Jingnan's capital Jiangling Municipality under siege. During the siege, the officer Zhao Kuang () plotted to rescue Chen Ru from imprisonment. When Zhang realized this, he put Zhao and Chen to death. Meanwhile, the food supplies ran out, such that the people resorted to eating human corpses. However, Qin Zongyan was unable to capture the city, and withdrew in late 886.
