 For example, in the match between Ni Yuk Tong (倪沃棠) and Wong, various accounts of the fight exist, and no one is sure of where the fight took place, how the fighters performed, and who won.Thus, while many of Wong's students have referred to him as "one of the greatest fighters of this century" (i.e., the 20th century), those outside the wing chun community could doubt the claim's authenticity.Wong's participation in, and views on, tournaments reflected his philosophy on martial arts.
