When Su Shi was in Pengcheng, Dao Qian made a special trip from Hangzhou to visit him. At the banquet, Su Shi wanted to play a joke on Dao Qian, so he found a prostitute to ask him for poems. At that time, Tao Qian said in a poem: "I owe it to your wife to make me angry with the king." The Zen mind has been stained with mud. Would you like to chase the spring breeze up and down? "
Su Dongpo was overjoyed when he saw it: "I tasted catkins falling into the mud and said that private things can be included in poetry, but I haven't cleaned them up. Unfortunately, this person is the first."
