""Looks like a text on moves. It explains moves I've never seen before. What move is this? A move of the Tiger Swallow Style, Zhuanshen Shuanghuquan. A move combination unique to the Tiger Swallow Style. Lan Di knows all these moves. Zhu seems to know a lot about the Tiger Swallow Style, he's done much research on the Tiger Swallow Style. Why did Zhu spend so much effort researching the style?

It's thoroughly explained. Did Zhu write this? It explains about the Tiger Swallow Style. The Tiger Swallow Style is a style derived from Yanqingquan. A combination of Dahuyan and Xiaohuyan. Has strong hand moves, as powerful as a fierce tiger. Feared by the Emperors of the past and thus prohibited. A style prohibited by the Emperor Yanqingquan. The origin of the Tiger Swallow Style seems to be Yanqingquan."

also is Yanqingquan internal kung fu?
