Sun Bin
In 341 BC, Wei attacked Han. Qi allowed Han to be nearly defeated and then intervened. The generals from the Battle of Guiling met again (Sun Bin and Tian Ji versus Pang Juan), using the same tactic, attacking Wei's capital. Sun Bin feigned a retreat and then turned on the overconfident Wei troops and decisively defeated them at the Battle of Maling. After the battle all three of the Jin successor states appeared before King Xuan of Qi, pledging their loyalty.
