Su Dongpo, a layman, wrote a poem, asking extremely young people to take a boat from Guazhou in the north of the Yangtze River to the south of the Yangtze River, and dedicated it to the Zen master Fo Yin of Jinshan Temple to correct me. He said: "The first day of the day was in the sky, the light was shining, and the eight winds could not move, sitting on the purple lotus." After the Zen master finished reading it, he immediately approved the word "fart" and asked the extremely boy to take it back. Dongpo saw his great anger and immediately crossed the river to question Fo Yin's Zen master. The Zen master said to him, "From the perspective of poetry, your cultivation is very high. Since the eight winds can't blow, how can we cross the river with a fart? " Dongpo was speechless and lamented that he was not as good as the Zen master. Su Shi and Fo Yin often make couplets together. Once, Fo Yin cooked a dish of fish. When he was about to eat it, he suddenly heard someone come in and hid the fish in a stone on the table. The bearer is Su Shi. After taking a seat, Su Shi said, "I have nothing to do today, and I just want to get married with you." So Su Shi revealed a commonly used couplet of Spring Festival couplets: "The first spring in Xiangyang is always there". Fo Yin didn't know there was a trap in it, so he easily answered the second couplet: "Accumulate good deeds and celebrate." Su Shi said, "Since there are fish in the rock, take them out to entertain guests." Fo Yin this just know cheated. It turned out that Su Shi smelled the fishy smell as soon as he entered the door, and there was no other place to hide indoors, so he naturally thought of the big mouth copper pot.
