An answer to an incoming kick is the Boi Jeung (literally back of palm), which is one of the many tools a Bak Mei practitioner can utilize to counter a kick, close the distance, and jam/disrupt the opponents attack. With the Boi Jeung two basic permutations can be used. The first method would be a simple stop hit, and the other would be used as a kick catch into a sweep.
