These points or a combination of these points are used to attack and manipulate the opponents during a fight. Martial artists treat themselves by massaging the acupressure points to remove blocks in their meridians.

They claim that this increases the circulation of energy and also provides them with flexibility by maintaining the softness of these points and also to make them less vulnerable to attacks.
