Zhang Cheng
When Sun Quan still held the nominal appointment of General of Chariots of Cavalry () in the late Eastern Han dynasty, he recruited Zhang Cheng to serve as an assistant official in the west bureau of his office. Later, he promoted Zhang Cheng to the position of Commandant of the West Section of Changsha Commandery (). During this time, he pacified some local tribes in Changsha Commandery and managed to recruit 15,000 of them to serve in the Wu army.
