What is the specific allusion of Guiguzi's exile?

The truth is not what you say. Guiguzi is knowledgeable and covers a wide range, including military and sophistry. He took an apprentice in Guiguzi, so that anyone can learn and let others leave unhindered. His intention is to bring out a few people who are willing to cultivate immortality with him.

There are four famous students: Su Qin and Zhang Yi study sophistry, and Sun Bin and Pang Juan study military affairs.

First, Pang Juan thought he had learned something and offered to go down the mountain. Mr. Guigu asked him to pick a mountain flower for his divination. Pang Juan first pulled out a sunflower on the mountain, but he didn't think it had strong vitality and threw it away. Unfortunately, there were no other flowers on the mountain at this time, and the sunflower he had pulled out before had withered after being exposed to the sun, so he had to pick it up and hide it in his sleeve. He told Mr. Guigu that there were no flowers on the mountain, but Mr. Guigu saw through them and Pang Juan had to offer them. Mr. Guigu is occupied by flowers: this flower blooms 12 petals, which should be your prosperous years; This flower has been entrusted and was collected in Ghost Valley. Ghost Committee is a Wei word, so it should be in Wei; But you finally cheated others and cheated others; The last code word is to meet a sheep, be honored to meet a horse, and die. Pang Juan came to Wei after going down the mountain and met Wang Wei who was steaming sheep. Wang Wei valued him because he was good-looking and had military talent. Wang Wei also knows that Pang Juan has another classmate, so let him recommend him. He was going to write to Sun Bin, but later he was jealous of him, afraid that he would gain power, and set him up to harm him, so that Sun Bin was punished! Sun Bin later fled to Qi, and finally killed Pang Juan's design in Maling. It was the sheep who died in worship of the horse.

After receiving the letter, Sun Bin also wanted to go down the mountain to find Mr. Guigu, and Guigu also asked him to pick a mountain flower. Sun Bin took a chrysanthemum from Mr. Guigu's desk vase and gave it to Mr. Guigu. Guigu also spends hexagrams: this flower is broken and finally honored, so it is bitter first and then named. This flower was taken out of the bottle and put back in the bottle, so your achievement is finally in your hometown (Qi people in Sun Bin). Finally, Mr. Guigu gave Sun Bin a copy of Sun Tzu's Art of War, written by Sun Bin's grandfather Sun Wu (Sun Wu and Guigu are friends), and Guigu has added comments. Sun Bin asked him why he didn't pass it on to Pang Juan. Guigu said that Juanjuan was not a good scholar. Later, Sun Bin changed its name to "Sun Bin" (Sun Bin's original name was "Sun Bin"), implying that Sun Bin would be punished. The consequences of Sun Bin's going down the mountain are just as Guigu said.

Su Qin and Yi Cheung, who were both studying sophistry in the mountains, became famous when they saw Sun Bin and Pang Juan both coming down the mountain. They also want to go down the mountain to find Mr. Guigu. Mr. Wang lamented that few people cultivate immortals. Su Qin and Zhang Yi said: A gentleman should make contributions all his life. Guigu had to let them go down the mountain, but warned them to help each other. So later Su Qin and Yi Cheung helped each other, and finally both of them made achievements.
