How many times did Song Wu's blood spill on the Yuanyang Building in Water Margin?

The Water Margin is the 31st time that Song Wu spilled blood on Yuanyang Tower.

In the thirty-first chapter of Water Margin, Zhang Dujian's blood splashed on the Yuanyang Building, and the martial artist went to centipede ridge at night. It is said that Song Wu passed the Cross Slope Hotel on his way to Mengzhou, and saw through Sun Erniang's antiperspirant wine and fought with it. Zhang Qing rushed to the vegetable garden at the critical moment to comfort them, and the husband and wife made friends with Song Wu.

In Mengzhou, Song Wu was taken good care of by Jin Yanbiao. In return, Song Wu beat Jiang Menshen as drunk as a fiddler and helped Kindness recapture the Happy Forest Hotel. However, Song Wu was also countered by Jiang Menshen in collusion with the government and was forced to kill. Blood spattered on the mandarin duck building, writing "The murderer killed Song Wu".

The story of Song Wu's blood splashing on the mandarin duck building;

In the process of escaping after the blood of Song Wu spilled on the Yuanyang Building, he got the help of Zhang Qing and Sun Erniang, pretending to be a "walker" and practicing with his hair. Zhang Qing and Sun Erniang asked Song Wu to vote for Erlong Mountain.

Then I went to centipede ridge at night and killed the evil flying centipede Taoist Wang in the grave. On the way, I knocked down Kong Liang because of misunderstanding, and fell asleep by the river after being drunk. Kong Liang caught him in Zhuangzi and tortured him. Fortunately, he clarified Song Jiang's misunderstanding in Kongjiazhuang.

After Song Jiang and Song Wu left Kongjiazhuang, Song Jiang prepared to go to Qingfeng Mountain and Song Wu prepared to go to Erlong Mountain. They went to Erlong Mountain in Song Wu respectively. Later, he became one of the three leaders of the "rebel army" and finally returned to Liangshan when Sanshan played Qingzhou.
