Zhang Liang
In 209 BC, when uprisings occurred throughout China to overthrow the Qin Empire, Han Cheng joined Xiang Liang's rebel force in the hope of reviving his native state. Along the way, he met Zhang Liang, a descendant of a bureaucratic family from the former Hán state. Zhang Liang succeeded in persuading Xiang Liang to restore the former Hán state and Han Cheng was appointed as its ruler with Zhang Liang serving as his chancellor. Xiang Liang also provided some troops to Han Cheng and allowed him to attack the Qin garrisons at Yingchuan (in present-day Henan).
