Career
He was one of the biggest impulsors of those arts outside China, being their first teacher in Taiwan and Japan. Shujin started training at 18 under renowned matser Zhang Zhaodong, who he served until his death 1940. He learned as well zhanzhuang qigong under Wang Xiangzhai.
Wang moved to Taiwan in the 1940s, and he taught martial arts in Japan in the 1950s and 60s.
He would initiate eight known disciples during his lifetime: Chao Piaosheng, Huang Jinsheng, Jibiki Hidemine, Lai Tianzhao, Rottmann Manfred, Wang Fulai, Zhang Yizhung and Wells Marnix. A man of almost 300 pounds, he was considered one of the greatest Chinese fighters, and it was said that his control of zhanzhuang and his immense strength and toughness enabled him to absorb the impact of strikes which would knock out a common persona.
Shujin challenged him to hit him in the stomach with all his power, claiming he would absorb the blow, but Lous refused, on the saying he didn"t want to kill Wang by accident. Wang famously hated karate, claiming it was a martial art only valid "to fight children and old women, and it is said Shujin competed against several karate practitioners in Japan, leaving undefeated in all of them.
Another anecdote supposedly saw karateka Jon Bluming injurying his wrist when attempting to hit Wang in the belly during a sparring.
Bluming, however, has stated that he was just white belt in karate at the time, and that although it is true that Shujin absorbed his punch, Bluming wasn"t injured, nor he considered it a special skill given Shujin"s size and build.
