Hua Lin: its one move.
WhiteMonkey: I agree with Mantis Cool on that. He described it very good. I often teach that move without blocking, because in move two (the Tong Long Bou Sin - Mantis Catches Cicada) you catch the opponents arm and follow him while he was retreating. Not necessarly a new block is to make, but of course could.
The palm strike must be powerful and main target is the chest. But also you could attack the face.
Itīs not only a transitional move!!! Itīs a full move and must be performed like one (in both roads!).
So what is your application for the three techniques after Ba Wong Ching Haak (Double grabbing hand in Ma Bo)?
I mean:
Dang San Bo - Diu Sau followed by Pek Cheui (Bow Stance with Mantis Hand and Chop)
Dang San Bo - Au Lau Choi (Hook Grapple Pluck)
Step - Kwa Fu Bo - Siu Fan Che Cheui (Step in Tiger Riding Stance - Little Turning Wheel Punch)
