Are any of you here a student of Sifu Robert Chu in LA? I've read his articles and articles about him and it seems he has a very wide background. Can I ask what the classes are like? Does he just teach Wing Chun (and if so, which particular version - if more than one, how are the classes structyured?)? If not, does he also teach other arts he has learned (like Hung Ga or Hsing I)?
