i think li yau san had never heard of Choy Fook, so both CHan Heung and Lee Yau San went to Choy Fook to meet him. after choy fook destroyed the corner piece of the grinder in his palm Lee Yau San skipped out and left CHan Heung there with Choy Fook.


from what i understand as well, is that Lee Yau San was jeong Yims sifu as well. this is coming from fut san hsk.
