Steeeve:

I see that you are training with Uncle Bill. He is a great master. I saw some of his and his disciples' clips. Ngo Cho Kun (at least the one that I know) and Uncle Bill's martial arts share identical major principles. Of course, there minor differences and also power generation methods might vary.

One example will be in the sa khak ho (triangular steps). I see that Uncle Bill is big in it from the way he moves. Xiamen lineages also emphasize this.

Quanzhou lineages, especially Lo Ban Teng and Kong Han, prefer tank-like direct approach (although it doesn't eliminate the side stepping).
