Han Xin
In 209 BC, Han Xin joined Xiang Liang's rebel army when rebellions erupted throughout China to overthrow the Qin dynasty. Han Xin continued serving Xiang Yu (Xiang Liang's nephew) after Xiang Liang was killed in action at the Battle of Dingtao. He was not placed in high regard and worked as a sentry and prepared meals. He constantly proposed strategies to Xiang Yu but was ignored. In 206 BC, Han Xin deserted Xiang Yu's army and went to join Liu Bang.
