Internal martial artists taking strikes/kicks to their bodies,is this true?

I´ve read that the trick is to put your ki to the area of the impact.
How does it work? I´ve also read that these artists are mostly cheating.

When all you change is your own body, it’s not a trick.~

There might be at least some who claim internal skill and use illusion to trick you into buying what they are selling/offering.

Very some such, perhaps might have been, likely say some, some not.

Nei Gong

Those who practic Wu/Ng Style Tai Chi Nei Gong will tell you that there is no trick just Kung Fu (hard work). Good luck in finding one who teaches that.
