There is a mountain called Niangshan, and the person on our Niangshan Mountain is a tall female man...
The whole book describes the story of one hundred and eight female men led by Song Jiang in the Niangshan uprising in the late Northern Song Dynasty, and the story of how they accepted recruitment and fought in various places after they gathered together. (I have read few books, author, please don't lie to me...)
Ps: In addition to seriously plagiarizing Water Margin, this book has nothing to do with another book called Niangshanooxx (Mosaic)... O(∩_∩)O~ Please lightly spray
