"King Kong rammed clams" is a kind of boxing action in Chen-style Tai Ji Chuan, which is characterized by "holding the ball with both hands, turning and standing, alternately pounding the ground with both hands, holding the ground with one hand, moving like a clam rammed, with the center of gravity still, and the body exerting force from bottom to top and from inside to outside".
"Heart-protecting boxing" is another boxing action, which is characterized by "the palm of the right hand is down, the left hand is lifted in vain, the right hand is pushed forward, the right foot is lifted in vain, the right hand is slapped to the right, the left hand changes hands, the right foot is stepped out in vain, and the left hand is lifted in vain".
Generally speaking, the two kinds of boxing moves are different in action form, starting method and technology, but they are both one of the classic boxing methods in Chen-style Tai Ji Chuan, which need to be constantly understood and experienced in practice.
