Taishi Ci
After pacifying eastern Danyang Commandery, Sun Ce led his troops to attack Zu Lang at Lingyang County (west of present-day Taiping County, Anhui) and captured him. Although Sun Ce almost lost his life in an earlier battle against Zu Lang before he started his conquests, he spared Zu Lang and allowed him to serve as his subordinate. Later, Sun Ce defeated Taishi Ci at Yongli County (in present-day Jing County, Anhui) and captured him. Sun Ce freed Taishi Ci and succeeded in persuading him to be his subordinate. When Sun Ce's army marched back in triumph, both Taishi Ci and Zu Lang were in the lead. With his victory, Sun Ce gained control over the six counties west of Jing County and fully secured three commanderies in the Jiangdong region.
