Pang Juan

Pang Juan was a fellow student of Sun Bin and both of them studied military strategy together under the tutelage of the hermit Guiguzi.

Pang pretended to take pity on Sun and tried to trick him to compile his knowledge about military strategy into a book and kill him later.

A struggle between Pang Juan and Sun Bin began, as each of them led his respective state's armies to attack the other.

Pang was eager to defeat Sun Bin and he led a light cavalry unit in pursuit, but fell into an ambush by the Qi army in a narrow valley at the Battle of Maling.

At that moment, the Qi troops lying in ambush attacked and Pang Juan committed suicide under that very tree.
