庞涓
In order to mislead his enemy, Sun Bin ordered his soldiers to make less stoves (cookfires) day by day. On the first day, Qi had enough stoves for 100,000 people; on the second day, there were stoves for only 50,000 people. On the third day, there were only stoves for an army of 20,000. As Pang Juan saw this, he judged that the soldiers of Qi were deserting their army and decided to pursue the Qi army with a small elite cavalry. This unit was overconfident following their recent victory in Han. As Qi retreated into their own territory, Sun Bin ordered his troops to abandon some of their heavy artillery. This further gave the impression of a state of confusion amongst the Qi army. As Qi arrived at Maling, Sun Bin noticed a heavily wooded and narrow pass that could be used for ambush. Estimating the arrival of Pang Juan around nightfall, he ordered his men to cut down a tree, remove its bark, and carve the words "Pang Juan shall die in Malingdao, under this tree" on its trunk. This was a proverb spoken by the teacher of both Sun Bin and Pang Juan (both had been in the same class).
