Yan Qing
Zhou Tong's connection to the art comes from a list within the Luohan Xinggong Duan Da manuscript. The work individually lists each of the eighteen masters and their contribution. Yan Qing (#7), the adopted son of Lu Junyi and Zhou's fictional grandstudent, is listed as a master of "Sticking, Grabbing, and Falling" and Lin Chong (#13) is listed as a master of “Mandarin ducks kicking technique” (Chuojiao). The manual records Wang Lang “absorbed and equalized all previous techniques” learned from the 17 other masters to create Mantis Fist.
