The Warring States policy requires a detailed story of Ghost Valley going down the mountain.

It was originally a historical story in the Warring States Policy that Ghost Valley went down the mountain, also known as "Ghost Valley came out of the mountain".

The story of "Ghost Valley Down the Mountain" comes from Warring States Policy. The story tells that during the Warring States Period, Yan and Qi fought, and Sun Bin, who worked for Qi, was captured by the enemy. His master Guiguzi went to the rescue and led the people down the mountain. Ghost Valley Down the Mountain, a blue-and-white figure jar in Yuan Dynasty, depicts the scene of Ghost Valley down the mountain: Ghost Valley sits on a two-wheeled cart pulled by liger, followed by two riders, one of whom is dressed as a military attache and carrying the flag of "Ghost Valley".

Guiguzi was a famous strategist in ancient China. Finally, he taught Sun Bin, Pang Juan, Su Qin and Zhang Yi. Guiguzi especially loved Sun Bin, who was sincere and sincere, and awarded Sun Bin his lifelong Juexue.

Pang Juan is also a student of Guiguzi and has also studied the art of war. On one occasion, Pang Juan heard that Wei spent a lot of money to recruit talents, and he was determined to be an official in Wei. Guiguzi has the power of destiny. I knew it for a long time, so I said to Pang Juan, You go out and pick a flower for me, and Pang Juan will pick a small flower and take it with you. Guiguzi saw this kind of flower called "Aristolochia", and it bloomed 12 times. He warned Pang Juan that you would enjoy the wealth of 12 years. This flower was picked in Guigu and withered at the sight of the sun. That's just a sign next to the ghost. Guiguzi also warned Pang Juan not to deceive others. If you want to deceive others, then you will be fooled by others. Finally, I gave Pang Juan eight words: "Be proud when you meet a sheep, and die when you meet a horse." Later, Pang Juan didn't listen to Guiguzi. Out of jealousy, he not only cheated Sun Bin, but also brutally persecuted him. Finally, he was taken in by Sun Bin and killed by Wan Jian on Maling Road, and the retribution was not good.
