The full text and annotations are translated as follows:
Fang Shanzi is a hidden person between Guang and Huang. When I was young, I admired the Zhu family and Guo Xie, and all the heroes in the village followed them. When I was a little stronger, I read at every turn, hoping to ride on in the world, but I didn't meet him in the end. In the evening, he escaped between Guang and Huang, and he was called Qiting. He lives in a nunnery and eats vegetables, and does not interact with the world. He abandons his carriage and horses, destroys his hat and clothes, and goes to and from the mountains on foot, so that no one knows him. Seeing that the hat he was wearing was square and high, he said, "Is this a remnant of the ancient Fangshan crown?" So he called him Fangshanzi.
I was relegated to Huang. I passed by Qiting and saw Yan. He said: "Wow! This is my old friend Chen Zhen Jichang. Why is he here?" Fang Shanzi also asked me calmly why he came here. That’s why I told you. He looked down without answering, but looked up and smiled. Call Yu to stay at his home. He was surrounded by Xiao Ran, but his wife and slaves all felt contented.
Yu Ji was surprised. I remember that when Fang Shanzi was young, he used wine like a sword and money like dung. Nineteen years ago, I was in Qixia. I saw Fang Shanzi riding two horses and carrying two arrows, traveling to the west mountain. Fang Shanzi's angry horse came out alone and got it with one shot. Because he and Yu Ma discussed the use of troops and the success and failure of ancient and modern times, he called himself a great man. In the past few days, I can still see the fierce look between my eyebrows, but it doesn’t belong to people in the mountains!
However, it has become known that Fang Shanzi has a distinguished family in his generation and should be given an official position to work among them. And his family is in Luoyang, with a magnificent garden and house, just like the princes. He has fields in Hebei, and he can get a thousand pieces of silk every year, which is enough for him to be rich and happy. They all abandon it and don't take it. They come alone to the poor mountains. How can this be nothing?
There are many strange people in the room between Yu Wenguang and Huang, who are often very dirty and dirty, and cannot be seen. How can Fang Shanzi see them?

Reference translation:
Fang Shanzi is a hermit in Guangzhou and Huangzhou. When he was young, he admired Zhu Jia and Guo Xie, the knights of the Han Dynasty, for their character, and all the knights in the village respected him. As I got older, I changed my interests and started studying hard, hoping to become famous in the contemporary world, but I never had good luck. In his later years, he lived in seclusion in a place called Qiting in Guangzhou and Huangzhou. They live in huts, eat vegetarian food, and do not interact with all walks of life. He gave up riding in cars and horses, destroyed the scholar's clothes, and walked back and forth in the mountains. No one knew him. When people saw that the hat he was wearing was square and high, they said, "Isn't this what remains of the Fang Shan crown worn by ancient musicians?" So they called him "Fang Shanzi".
I was demoted and lived in Huangzhou. One time when I passed by Qiting, I happened to meet him. I said, "Ah, this is my old friend Chen Zhen and Chen Jichang, how come he lives here?" Fang Shanzi also asked me in surprise why I came here. I told him the reason. He lowered his head and said nothing, then laughed up to the sky and invited me to stay at his house. His home was in a state of depression, but his wife, children, and servants all appeared to be enjoying themselves.
I was very surprised by this. I recall that when Fang Shanzi was young, he was a knight-errant who was fond of drinking and wielding swords, and spent money like water. Nineteen years ago, when I was in Qixia, I saw Fang Shanzi hunting in the Western Mountains with two horsemen and two arrows hidden in his body. He saw a magpie flying in front of him, so he asked his followers to chase the shooting magpie, but failed to hit it. Fang Shanzi tightened the reins, jumped forward on his horse alone, and shot the magpie with an arrow. He immediately talked to me about the use of troops and successes and failures in ancient and modern times. He considered himself a hero of the generation. How many days have passed, but a heroic look still appears between the eyebrows. How could this be a person who lives in seclusion in the mountains?
Fang Shanzi was born in a family that has made meritorious deeds for generations, so he should be an official. If he could enter the officialdom, he would have achieved the honor of a high official by now. His original home was in Luoyang. The gardens and houses were majestic and magnificent, comparable to the homes of princes and princes. There are still fields in Hebei, and one can earn thousands of pieces of silk every year, which is enough to make one's life rich and comfortable. However, he put them all aside and came to a remote ravine. Isn't this because of his unique understanding?
I heard that there are many strange people in Guangzhou and Huangzhou. They often pretend to be crazy and wear shabby clothes, but I can't see them. Fang Shanzi might be able to meet them.
