What is the anti-poem written by Wu Yong in Lu Junyi's home in Water Margin?

There are boats on Luhuatan,

Jie Jun swims alone at dusk.

Justice is the end of life,

There is no need to worry about running away.

This is a Tibetan poem written by Zhi Duo Xing Wu Yong. When the first word of each sentence is read together, it means "Lu Junyi is against". It also hints at Lu Junyi's escape route.

This poem is from Water Margin, one of China's four classical novels, and it is also one of the earliest vernacular novels in China history. The writer is Shi Naian. The story mainly tells the story that 108 heroes headed by Song Jiang gathered in Liangshan at the end of the Northern Song Dynasty, accepted the enlistment after the rally, and fought everywhere. It vividly depicts the whole process of the uprising from its occurrence, development to failure, profoundly reveals the social roots of the uprising, enthusiastically praises the resistance struggle and social ideals of the uprising heroes, and specifically reveals the internal historical reasons for the failure of the uprising.
