Huang Shigong is from Xiapi. He was anonymous when he met the war in the Qin dynasty, and no one knew him at that time. At first, I changed my surname to Chang and hid in Xiapi. When he was walking on the bridge in Yishui, he met an old man he had never met before. Huang Shigong deliberately threw his shoes under the bridge, looked at Sean and said, "Boy, go down and bring them up!" " Sean didn't know in advance that it was a fraud, and some were startled to beat him; Seeing that he was old, he choked back his anger and got off the bridge to get his shoes. So I knelt down and put it on him. The old man put out his foot, let Sean put on his shoes, and then left with a smile. Sean was very surprised. He walked about a mile and came back. He said to Sean, "Young people can be educated! You will meet me here in the morning in five days. " Sean was even more surprised and knelt down and said, "Yes." Five days later in the morning, Sean went to the appointed place. Huang Shigong said angrily, "You have an appointment with the old man. How did you come later? " Five days later, in the morning, Zhang agreed to leave before dawn and arrived early. He said angrily, "Why are you late?" Five days later, Sean left at midnight. After a while, Huang Shigong also came and said happily, "It should be like this!" " "So he took out a book for Sean and said," If you go back and read his book, you can be the emperor's teacher. Thirteen years later, the Yellowstone you saw at the foot of the ancient city of northern Hebei was me. " So he left and disappeared. Zhang opened the book and saw that it was Sun Tzu's Art of War. Sean thought it was incredible, so he lobbied around, but they didn't adopt his theory. Later, I met Pei Gong in Chenliu, and Pei Gong adopted his words and finally had a career. Thirteen years later, he followed Gaozu back to the foot of the ancient city in northern Hebei and got a piece of Yellowstone, so Sean built a shrine to worship it like a treasure. Until Sean died, he was buried with the stone.
