 Zhou can also be linked to these combat arts through his historical and folklore students . Practitioners of Eagle Claw , Chuojiao and Xingyi commonly include him within their lineage history because of his association with Yue Fei , the supposed progenitor of these styles . <unk> <unk> believes Zhou taught Lin Chong and Lu Junyi the " same school " of martial arts that was later combined with seventeen other schools to create Mantis fist . This combination of various schools refers to an eighteenth @-@ century martial arts manual that describes the gathering of eighteen masters at the Shaolin Monastery that supposedly took place during the early years of the Song Dynasty . Lin Chong and Yan Qing are listed as two of the eighteen masters invited , which means their skills of Mandarin Duck Leg and ground fighting are treated as two separate schools , instead of one . But he believes Mantis fist was created during the Ming Dynasty , and was therefore influenced by these eighteen schools from the Song . He also says Lu Junyi taught Yan Qing the same martial arts as he learned from Zhou .
