When Cheung Chui San first met Golden-Haired Lion King Tse Tsun, Cheung concluded that Tse's martial arts rivaled those of Cheung's teacher, Cheung 3 Fung. Of course, Chui San's assessment of Tse's martial arts level was way, way off, but it's easy to see how Chui San overrated Tse Tsun so much. Cheung Chui San himself was quite an excellent fighter even at the beginning of HSDS; up until that point, he had not encountered a foe whom he could not defeat fairly easily (all those Sea Sand Sect, Dragon's Gate Courier Agency, Shaolin, and Heavenly Eagle Sect guys he beat so easily in those early parts of the story), but he knew that Tse Tsun was at a much, much higher level than himself.
Tse Tsun did look quite awesome in his first appearance - easily wasting scores of Kunlun Sect, Sea Sand Sect, Great Whale Sect, etc., people, and making even Bak Gwai Sau, Yan So So, and Cheung Chui San look like complete chumps by comparison. Still, we know that Tse was still far, far below Cheung 3 Fung's level.
So how far below? How many Tse Tsuns would it take to equal one Cheung 3 Fung in a martial arts fight?
