Dog Kung Fu

Dog Kung Fu, i.e. Góuquán, i.e Dishuquan, is a southern style of Chinese boxing that

specialises in takedowns and ground fighting. This martial art also teaches Iron Shirt and Iron Palm fighting methods as well as specialized leaping techniques. It is mainly practiced in Fujian Province and was historically often practiced by women who were victims of foot binding, for whom any form of standing physical exertion was difficult. Its creation is traditionally credited to a Buddhist nun who developed the style to defend herself from bandits on her travels.

Chen Yijiu

During the early years of the Republic of China, Chen Ayin, a descendant of Chen Biao, fled to Singapore to escape imprisonment for accidental manslaughter when defending a friend against a village troublemaker. He was taken in by a one of the Chinese immigrants, Chen Yijiu. Being ever grateful, he taught Chen Yijiu his art without reservation.Chen Yijiu, already having learnt martial arts such as Muay Thai, Dragon Kung Fu, and Zui Quan, spent several years refining the techniques in Dishuquan and building himself a reputation in Southeast Asia as the "Iron Leg". He left Singapore in 1932 and moved to Xiyuan village in Fuzhou, where he resided until his death in 1997. There, he spent the rest of his years teaching Dishuquan, spreading the art around and through Fuzhou.
