In the early Warring States period, Wei was a famous soldier with outstanding military ability, but he was narrow-minded and jealous of talents.

Pang Juan and Sun Bin are classmates. They study the art of war together. Pang Juan later became an official in Wei and a general in Wei Huiwang, but he thought his talent was not as good as that of Sun Bin, so he secretly sent someone to invite Sun Bin to Wei to watch him. When Sun Bin arrived in Wei, Pang Juan was jealous of his talent, so he fabricated charges, sentenced Sun Bin to flogging, and cut off Sun Bin's feet to be buried in the world.

When the emissary of the State of Qi went to Daliang, the capital of Wei (now Kaifeng, Henan), Sun Bin secretly met the emissary of the State of Qi as a prisoner and touched him with words. The angel of Qi thought Sun Bin was extraordinary, so he secretly drove him back to Qi. Sun Bin, who fled to Qi, was appreciated by Tian Ji, so he lived under Tian Ji as a doorman.

Sun Bin once again used the tactics of besieging Wei to save Zhao, and led an army to attack Wei Du's girders. When Pang Juan learned the news, he quickly withdrew from South Korea and returned to Wei, but by this time the Qi army had moved westward. Considering Wei Jun's self-reliance, Sun Bin despised the Qi army, which also had a reputation of being afraid of war. We should take the tactics of luring the enemy in depth, luring the enemy in depth and annihilating Wei Jun.

Sun Bin ordered the Qi army in Wei to bury 100,000 stoves on the first day, and reduced them to 50,000 on the second day and 30,000 on the third day. Pang Juan marched for three days to check the stoves left by the Qi army, and he was very happy. He said: "I know that the Qi army is timid. It's only been three days since we entered the territory of Wei, and more than half of the Qi soldiers have fled. " So he left the infantry and only led the elite cavalry to chase the Qi army day and night.

Bin Sun estimated that Pang Juan can go to Maling after dark. Maling Road is narrow, with many steep passes and obstacles on both sides. Sun Bin ordered the soldiers to cut off the bark of the roadside tree, exposing white wood, and wrote "Pang Juan died under this tree" on the tree, and then ordered 10,000 crossbowmen to ambush on both sides of Maling Road, agreeing that "if you can see a fire here in the dark, there will be 10,000 arrows at once".

Pang Juan rushed to the tree whose bark had been cut off that night, and when he saw the words written on the white wood, he lit a fire to look at it. Before I finished reading the words, the Qi army ambushed thousands of arrows, and Wei Jun was in chaos. Pang Juan knew that the defeat was decided, so he drew his sword and killed himself.
