刘曜
In 322, while on a campaign against the Di chief of Chouchi, Yang Nandi, Liu Yao was stricken by a communicable disease, and while he was still able to force Yang to submit, his general Chen An, a former subordinate of Sima Bao, mistakenly thought that Liu Yao had already died, and therefore declared independence as the Prince of Liang, controlling most of Qin Province (秦州, modern eastern Gansu). In 323, Liu Yao, having recovered, personally attacked Chen's headquarters at Shanggui (上邽, in modern Tianshui, Gansu). Chen fled but was eventually captured and killed. Qin Province was once again Han Zhao domain.
