Throughout Wu's retro life, the most commendable thing is his friendship with Su Shi. Wu Fugu's father Ren Hanlin met Su Shi when he was a lecturer. Su Shi said this situation in "Book with Wu": "It is better to have the first lecture if you are less in the yamen. Life and death are broad and pitch for a lifetime. " Later, Su Shi learned from Li Shizhong's introduction that Wu Fugu was a man who had been in contact with poetry and books for many years. In the tenth year of Xining (1077), Su Shi moved from Mizhou to Xuzhou and passed through Qingzhou to Jinan, where he first met Wu Fugu. When Su Shi was in Huizhou, he once said to Wu Bizhong, the son of the retro style, in the book Answer to Wu Xiucai: "Ye Zi, as soon as he saw his servant, gave birth to life." "Although I can't do it, I like to recite his words. I will taste an article" Ask for Health "for Ye Zi." It can be seen that the first interview between the two was to discuss the way of keeping in good health. Wu Fugu's "birth method" is not only different from the immortal family's pursuit of immortality, but also different from the Taoist alchemist's taking medicine, which is obviously another spiritual realm of inaction and detachment. With the increasingly fierce political struggle, Wu's retro thought has its uniqueness. It's just that Su Shi still wants to make a difference in the face of the disadvantages of the new law, and he holds a "reserved" attitude towards this, but he greatly appreciates Wu's theory of health preservation. It is said that Su Shi also left a legal post for this purpose. Since then, Su Shi has been demoted to Huangzhou. He often sends letters of condolence and exchanges poems, epitaphs and calligraphy. In the sixth year of Yuanfeng (1083), I went to Huangzhou to inquire. It's a pity that Su Shi is "very ill and can't afford to pay." This is Su Wu's second meeting.

In the fifth year of Yuan You (1090), the king of Chu learned Chaozhou dialect, advocated the restoration of Korean temples, and asked Su Shi to write an inscription for the temples. After Su Shi finished writing, he sent a letter, tirelessly telling the sample of the tablet he designed, and solemnly confessed that "if the public office is replaced, it must be sealed by Wu Daochang"; "Ye Zi is sincere and the public can be very friendly." At the same time, I also wrote another letter, Talking with Zi Ye about Han Beishu. There is a saying in the book that "people in the cloud dynasty, although small people also know etiquette and righteousness, believe in madness." It can be seen that Sue has considerable trust in Wu. In the eighth year of Yuan You (1093), Su Shi was appointed as the magistrate of Dingzhou. Wu Fugu arrived in Beijing and met Su Shi again. Sue talked about it in a reference book: "I will go out of town to Dingzhou one day." This is Su Wu's third meeting. The following year, Su Shi decided to take charge of the affairs of the British state. Wu Fugu rushed to Calm and Yangzhou to bid farewell to Su Shi. Su wrote a poem entitled "Wu became a monk and gave him a mountain pillow screen". This is Su Wu's fourth meeting. In this regard, Su Shi also talked about it in his letter to Bi Zhong: "If it is true, you can see the wild and there is no mourning."

? In Shao Shengyuan (1094), Su Shi was demoted to Huizhou; After four years (1097), Qiongzhou was demoted. During this period, Su Wu got closer and closer. In three years, Wu Fugu visited Su Shi in Huizhou and lived there for more than three months. I once said, "I want to go to Xiaoyao Hall, and I want to die. I have drummed twice for knocking on the Luofu Taoist Temple in the Western Hills and stayed in the West Hall. " In Huizhou, Su Shi's calligraphy is retro, which can be confirmed by his works such as A Travel in Peace, Poems of the Soul of Keeping Books, Li Cheng's Ink Book, Braised Taro Sticks and so on. Su Shi wrote another poem, "It's a play to visit children to eat wild food and burn taro on New Year's Eve": "Spring breeze blows and hunger rings at night. Cow dung burns taro in the fire, and mountain people are lazier and more disabled. " Also at the right time. When Su Shi was demoted to Hainan, many old friends went to visit, or were stopped by Su Shi, or later than the action, or died on the journey. "Wu is the only one who has the courage." Su Shi's "This year, I lived in Suiju, and my son came back to meet you as a poem." There is a saying: "A joke is startled in the middle of the night, and the wind and rain are dark. The chicken sings the mountain pepper and the bell rings outside the frost. " Su Wu chatted for a while, laughing and laughing, showing the depth of their friendship. Other poems written by Su Shi in Hainan include Two Poems with Two Rhymes to Mr. Wu and About Wu and Jiang Junbi Eating Mushrooms. In addition, Su Shi has two poems, which point to the lips. The handwriting of these two words was originally hidden in the retro home. Fu Gan commented in the Remnants of Dongpo Ci: "Hongfu witnessed Dongpo's handwriting at Wu Ziye's home in Chaoyang." There are many Su Shihe in the Wu family, which shows the close relationship between Su and Wu.

? After that, Wu Fugu traveled to Huoshan Mountain in Longchuan. In the third year of Fu Yuan (1 100), Su Shi was pardoned and returned to the north. At the age of 96, Wu Fugu chased Qingyuan Gorge from Panyu with Guangzhou Taoist He Chongdao, and visited Guangling Temple (Feilai Temple) together on the fifth day of the lunar calendar 1 1 month/kloc-0. Up to now, Weng Fanggang wrote on the inscription on the east side of Dongpo Pavilion of Feilai Temple: "Dongpo's residence crossed the sea to the north, and three elders, Wu, He Chongdao, Kuan Tangtong, Huang Mingda and Li Gongbi, chased him from Panyu to Qingyuan Gorge in the forest and followed Guangling Temple." In the end, Wu Fugu was old and weak, and the weather was too cold to get sick. He died on the way home on April 13th of the following lunar calendar. Su Shi was shocked and very sad when he heard the bad news in Zhou Zhen. He wrote "Sacrifice to the Son", praising the mourning.
