Zhang Xun
In 197, Yuan Shu wanted to declare himself emperor and desired to have a neighbouring warlord, Lü Bu, as an ally. So he proposed a marriage between his son and Lü Bu's daughter. However, Lü Bu rejected the proposal after listening to Chen Gui's advice. In anger, Yuan Shu ordered his general Zhang Xun (張勳), with Yang Feng and Han Xian as his subordinates, to lead troops to attack Lü Bu. Lü Bu heeded Chen Gui's suggestion and managed to induce Yang Feng and Han Xian to turn against Yuan Shu. Yang Feng and Han Xian then joined Lü Bu in attacking Yuan Shu's forces, led by Zhang Xun, and defeated the enemy. After driving back Zhang Xun, Yang Feng and Han Xian led their men to pillage several territories until Zhongli (鍾離) before turning back. Later in 197, the warlord Liu Bei lured Yang Feng into a trap under the guise of a meeting and killed him.
