While working as a carpenter in Tianjin, Shujin started training at 18 years old under renowned master Zhang Zhaodong or Chang Chao Tung, who he served until the latter's death in 1940.

[3] He became an adept of the Yiguandao sect and moved to Taiwan in 1948, after which he befriended and trained under Chen Pan Ling, an apprentice to Yang Shaohou and Wu Jianquan.

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 zhan zhuang and his immense strength and toughness enabled him to absorb the impact of strikes which would knock out a common person.

[7] During the 1960s, Shujin taught in Japan such Western martial artists Donn Draeger, Phil Relnick, Robert W. Smith and Jon Bluming, living near the Kodokan Institute.

[8] Draeger, a judo 4th dan black belt, trained baguazhang for several years, and spoke admiringly of his time with Wang: "He came to my house and picked up a meteorite the size of a shotput that I used as a paperweight.

[10] However, Wang refused to spar with them, and Draeger and Bluming remained skeptical of Shujin's fighting skill, arguing that the ability to perform certain physical stunts did not necessarily mean to be a proficient alive fighter.

[3] This version is doubtful, given that Draeger was famously skeptical of the effectivity of Chinese martial arts until his death, even after his own extraordinary experiences with Shujin, and apparently never managed to get Wang to spar with him.

[5] Frantzis heard Wang had broken opponents' spines by pulling them against his belly pushes, though he was later taught it was possible to avoid this technique by turning sideways and receiving the blow with the hip.

[5] Frantzis also recounted Wang taught Taoist meditation and sexual practices to select students, and could himself increase the heat of his hands using qi control,[5] a skill also witnessed by Phil Relnick.

[5] According to Ellis Amdur, a terminally ill and seventy years old Wang once defeated a Kyokushin karate champion by stepping inside his attack, hugging him and throwing him down with his signature belly push.
