In the clip of Wu Song killing a tiger in The Water Margin written by Shi Naian in the Ming Dynasty, Wu Song raised his whistle and strode up to Jingyanggang. After walking about four or five miles, I came to the bottom of the hill and saw a big tree. The trunk was skinned and white, with two lines written on it. When Wu Song looked up, it said, "Recently, there was a big bug in Jingyanggang, but there were merchants in the past. You can gang up at noon and cross the gang. Please don't make mistakes."

Shi Naian (about 1296-137), a native of Xinghua, Jiangsu Province, was born in Baijuchang, Xinghua County (now Shijiaqiao, Xinduo Town, Xinghua City). His original name was Yanduan, whose name was Zhaorui, whose nickname was Zi 'an and whose nickname was Naian. Representative works include Water Margin.

According to legend, Shi Naian often taught students to draw when he was teaching in the mansion. He is strict, teaching only one figure painting at a time, and then teaching another one until the students have finished painting. He taught students to draw 18 pictures before and after. These paintings have different faces, different movements, different expressions and different personalities. The 18 characters he portrayed are said to be the 18 generals in Water Margin.

Mr. Liu Bowen once took part in two books and wrote in front of Emperor Hongwu, "Shi Naian is ten times better than a minister. If he is taught to be an official, he will definitely have good political achievements." Emperor Wu of Hong allowed him to play, and sent an imperial edict to Jiangyin to call him to Beijing. After several calls, he only shirked his illness and refused the imperial edict. He has a great ability. Apart from making a fuss, he can also treat diseases, divination, fortune telling, watching Feng Shui, boxing and so on.
