Zhang Xianzhong
Though the Qing under the leadership of Prince Regent Dorgon (1612–1650) had successfully pushed the Southern Ming deep into southern China, Ming loyalism was not dead yet. In early August 1652, Li Dingguo, who had served as general in Sichuan under bandit king Zhang Xianzhong (d. 1647) and was now protecting the Yongli emperor, retook Guilin (Guangxi province) from the Qing. Within a month, most of the commanders who had been supporting the Qing in Guangxi reverted to the Ming side. Despite occasionally successful military campaigns in Huguang and Guangdong in the next two years, Li failed to retake important cities.
