Ok, I think I actually know something about this one. Finally, a question that you don't have to be skilled at energy manipulation to answer! [

As far as I know, chi is the universe's energy. Ki is one's inner energy. Ki can have an effect on another person's Ki, but not their physical body. Jing is compressed Ki and can hurt people physically.
Please, correct me if I'm wrong, but this is the summation of what I've read so far.
