Goodmorning from The Netherlands!

Is there anybody who can tell me more about Master Sung Su Ming? Apparently he lived in the early 20th century and was said to be a lineal successor of Sung Yuan Chiao.

It was said that his skill was such, that he was challenged by capable boxers as Chi Te, Chiang Tien Chen and Wu Chien Chuan and defeated them all. After that, they bowed for him as students (source: Chinese Boxing: Masters and Methods by Robert W. Smith.

Via the internet I cannot get more info on this master. Nor can I find information that, for example, Wu Chien Chuan learned from this Sung Su Ming.

Thanks!

Francesco
