I'm not sure which song's lyrics are from 'A Pot of Muddy Wine' in 'Water Margin', because' Water Margin', a classical novel, and the song, a pop song, have some differences between them. However, if one had to choose a famous Water Margins song, then " Wu Song Fights the Tiger " might be a more representative one. This song was based on the plot of the classical novel Water Margins. The lyrics described the story of Wu Song fighting a tiger on Jingyang Ridge. The melody was beautiful and moving, and it was deeply loved by people.
