What is the strongest Kung Fu move in martial arts?
The palm strike.

Taught at most Kung Fu schools condition the palms to make said palm strike as damaging as possible. The reason the palm strike is so dangerous, is because for one, it is in fact more powerful than any kick, and because the blow is distributed throughout the palm it generates shockwaves throughout the entire body.

It doesn't matter either, if an opponent is fat; if the Kung Fu expert's palms are well conditioned, the shockwave generated can be so strong that the waves of his own fat could for example, break his ribcage.
