Sheng Chi Kung Fu

It's easiest to understand the meaning of these terms if you think of them in terms of a family. The Da' Shifu being the grandfather. The Shun Shifu being the eldest son of the grandfather. The Shifu's being the other sons of the grandfather. The brown belt is given the title Shi Bok because he would have a family responsibility but not a direct responsibility of raising the children (students). Like an uncle would. Shi Hing would also have a responsibility to the family but a lesser responsibility than the Shi Bok. Shi Hing is like an older cousin.
