Is “Wang Qing rebelled in Huaixi, proclaimed himself King of Chu, and was later conquered and captured by Song Jiang's army.” true?

In the actual late Northern Song dynasty, there were indeed small-scale popular uprisings such as Wang Qing's rebellion, but their scale and influence were far from comparable to Fang La's. Listing the four as the 'Four Great Bandits' is a worldview constructed by the novel. Chapter 105 of "Water Margin" writes that Wang Qing "then made Li Zhu his military advisor and proclaimed himself 'King of Chu'." The "History of Song" does not record that Song Jiang suppressed Fang La or Wang Qing. This plot is a fictional achievement transplanted and fabricated by the novel to showcase military prowess.
