Yan Qing
Lineage Mantis master Yuen Man Kai openly claims Zhou Tong taught Lin Chong and Lu Junyi the "same school" of martial arts that was later combined with the aforementioned seventeen other schools to create Mantis fist. However, he believes Mantis fist was created during the Ming dynasty, and was therefore influenced by these eighteen schools from the Song dynasty. He also says Lu Junyi taught Yan Qing the same martial arts as he learned from Zhou Tong. Yuen further comments that Zhou Tong later taught Yue Fei the same martial art and that Yue was the originator of the mantis move "Black Tiger Stealing Heart".
