Pak Sao

In Wing Chun martial arts, Pak Sao is a blocking technique similar to a parry used in boxing. With Pak Sao, the hand comes directly out of the center of the body to slap away an attacker's strike to one's head. Effective application of Pak Sao involves creating an angle of deflection through which the opponent's blow can be slapped away with minimal effort.

An overcompensating Pak Sao may allow the attacker a free shot. This is because excessive effort creates the risk of being trapped by one's opponent if said opponent pulls the Pak Sao down and traps one's other arm with it.
