There are also some Song Jiang Uprising in history, and there are 36 legendary leaders. Song Wu is one of the thirty-six highest plows. There may be a real person in history, but it should not be as written in the Water Margin. It is true that some people showed kindness to Song Jiang and his gang in history, but Hui Zong's chronicle only recorded so much. I looked at it, and Songshi didn't seem to mention Song Jiang and others. I just read the history of Emperor Gaozong, but I'm not sure if there is.
Therefore, there is no basis for Song Jiang to fight Fang La, let alone whether Song Wu participated in the war.
Historically, the task of pacifying Fang La has always been accomplished by our envoys. Tong Guan brought the legendary 6.5438+0.5 million troops, but it didn't play a decisive role. As for whether Song Jiang and others participated, it's hard to say.
