I've been studying Yang style Tai Chi Chuan for about 6 months and while I know that I am not qualified to teach I do practice at home. My wife has shown some interest in learning Tai Chi but is not interested in attending class with me but is interested in practicing with me. So my thought is I can teach her the form as I know it and as my form is refined hers will be too.

Like I said, I know I'm not qualified to teach but is there any harm in showing her the form so she can practice with me?
