Wang Su-jin

He died in 1981 in Taiwan due to a melanoma complicated by his diabetes.

In 1968 Bruce Frantzis, a 19 years old junior karate championship, trained with Wang in China. According to him, he was routinely dominated by Wang with baguazhang techniques every time they sparred. The Chinese master also allowed him to kick him full force in all his body, including his groin, without receiving damage. Frantzis heard Wang had broken opponent's spines by pulling them against his belly pushes, though he was later taught there were ways to avoid this technique. He further claimed Wang was undefeated in no-holds-barred challenges in Japan, that he had beaten down young challengers while in his eighties, that his students were equally strong even at the same age, and that Wang had several supernatural abilities related to qi.

In an anecdote on December 14, 1954, Wang met boxing champion Joe Louis while he was touring Taipei. Shujin challenged him to punch him in the stomach with all his power, claiming he would absorb the blow, but Louis refused on the saying he didn't want to kill Wang by accident.

During the 1950s, Shujin trained in Japan along with Western martial artists Donn Draeger, Robert W. Smith and Jon Bluming, living near the Kodokan Institute. Smith, who was similarly trained in baguazhang and xingyiquan, wrote that Wang "could do something beyond the ability of all the fighters I saw." The Chinese master could especially tolerate any kick to the lower body, excluding the groin. Upon request, Smith repeatedly kicked his ankle, calf and knee without any effect.

Working as a carpenter, Shujin started training at 18 years old under renowned master Zhang Zhaodong, who he served until his death 1940. He learned as well zhanzhuang qigong under Wang Xiangzhai. He also trained xinyiquan under Wang Xiai Zhai, disciple of Guo Yunshen, and other styles under Chen Pan Ling, apprentice to Yang Shao-hou. He became an adept of the Yi Guan Dao sect and moved to Taiwan in the 1940s. From the next decades until the 70s, he did frequent travels to Japan, where he taught Chinese martial arts.

Wang Shujin (1904-1981), also known as Wang Heng Sun, was a Chinese martial artist, expert in the disciplines of baguazhang, taijiquan, and xingyiquan. He was one of the biggest impulsors of those arts outside China, being their first teacher in Taiwan and Japan, and was particularly known for his challenges to other martial artists. Wang was also a spiritual leader in the Taoist sect Yi Guan Dao.
