Only an expert should teach

Being a tai chi teacher is more than just talent.
You need to put in the work.
This is why there is an instructor training course for would-be instructors.

An expert must have at least 10,000 hours of practice behind them.
Dr. K. Anders Ericsson found that this was true of any art; whether tai chi, dancing or playing the piano.

You should only seek to become a tai chi or baguazhang instructor when you are an 'expert'.
