In xiao hong quan the is a vertical strike with the edge of the hand. it is used throughout the form. i was given a simple application for this move from my teacher ,but was not satisfied with it. I feel this strike can be used/was designed for defend against front grab attempts,such as a two handed choke attempt,a double handed lapel grab or front bear hug attempt. because the hand is vertical and knifed and the strike comes straight down the middle,it can fit easily between the opponents grabbing arms.
does anyone know any applications or theories for his strike,other then simply strike the guys chest? seem like such an awkward way to put your hand and arm simple to strike a guy in the chest.
