If you want to learn more about Tai-Chi, here are some suggestions:
Rent a DVD or check one out at your local library. This will
give you some good visuals- even those dreck ones.
Buy or check out a book. This will give you some great
background of the art and explain a lot of the history, tradition, and theory
behind Tai-Chi and Qigong.
Call a school. Most schools will happily let you sit in on a
class or two to observe, and every Martial Art instructor worth his or her salt
loves to talk about the style they practice.
