Zhang Liao
Towards the end of the Eastern Han dynasty, Ding Yuan, the Inspector of Bing Province, heard of Zhang Liao's combat skills and hired him as an assistant officer. Ding Yuan ordered Zhang Liao to lead troops from Bing Province to the imperial capital, Luoyang, to assist the General-in-Chief, He Jin. He Jin then sent him on a mission to Hebei, where Zhang Liao managed to recruit over 1,000 men to serve in He Jin's army.
