Jade Body/Qi Gong Sets

Can anyone teach me what these are, and how they work? What do they strengthen?

Why do people say learning alone is dangerous. This seems erroneous to me, like saying to can strike your nerve points and knock yourself out. You cannot.

If they are so dangerous, why bother?

yes you can I learn all my moves on my self I have given my self suvere migrains and have blured my vision for several second at times

One of the very dangerous parts of doing Qi Gong incorrectly is the breathing, if you attempt zen/buddist breathing methods or taoist beathing methods and do these wrong, while doing the energy forms, it can seriously mess up your innards, giving you major gastrointestinal problems, and Ive actually even heard of hemmoroid outbreak s(though i cant verify this, as its never happened to me) and many other things can happen, especially if you attempt high level stuff when just beginning.
