In the Qing Dynasty, Li Diaoyuan, a gifted scholar in Shu, visited a temple in the mountains. The elder heard his name and invited him to the abbot's place to entertain guests. After dinner, the elder said he had something to ask. It turned out that there was a picture of lotus in the temple, which was painted by the elder. At that time, after the painting was finished, Tang Bohu happened to visit here, and the old monk asked him to write an inscription on the painting. Tang Bohu did not refuse, but wrote an inscription on the painting "Draw a lotus and a monk". After writing, he said to him, "If anyone can draw a bottom line after I leave, this person must be today's wizard!" At first glance, Li drew the second word, which was an authentic original, and soon discovered the beauty of this couplet: it belonged to a palindrome couplet, and it was homophonic, with the same pronunciation. Seeing that Li was thoughtful, the elder prepared pen and ink and said, "Please add icing on the cake!" Li Tiaoyuan wrote a couplet next to the first couplet of Tang Bohu: "This book is close to the Chinese character Hanlin." These seven words are read backwards, and the pronunciation of the words is exactly the same as that of the reading, which is very consistent with Tang Bohu's first couplet, and the elders applaud. Since then, this painting has become a treasure of this temple.
