As throws are often used in kungfu, it is necessary for students to know how to break their fall to prevent injury like fracturing their arms or dislocating their elbows. As a student falls to the ground, his palm should be the last, not the first, to hit the ground. If he is untrained he would frequently try to stop his fall with his hand.
This may result in fractures or dislocations. However, breaking falls is not often used in actual combat because by that time kungfu exponent would know how to neutralize or counter the felling techniques of an opponent. It is during the training when they allow their partners to throw them that breaking falls is essential. Without this ability it would be difficult to train realistically.
