According to this page from 2003, the book Northern Praying Mantis Black Tiger Intersectional Boxing talks about Zhou Tong teaching various boxing styles to his students Yue Fei, Lin Chong, and Lu Junyi. I'm pretty sure this is the same book that the person was referring to.
(Before I continue, I know the fictional bandits were never Zhou's historical students, which makes his supposed ties to Mantis boxing nothing but legend!!! The only reason I write loudly is because some people tend to skip over stuff that i write and explain the same things back to me.)
If someone on here has the book, does it actually say that stuff? I don't want to spend money on a book that just has the same title of another (which I've seen before). Thank you in advance to whomever answers by questions.
