What exactly does Qing Gong (lightness technique) encompass? If you have good qing gong, does it mean you are able to 1) jump up and down very high, AND 2) jump up and down very fast? To me, being able to leap high doesn't necessarily mean you're able to do it fast. Also just because you're very fast doesn't mean you are able to leap high.
What about someone who is extremely fast overall but cannot jump as high as someone who is slower than him, does she still have good qing gong?
