Believe it or not, tai chi is so far the most advanced martial art in the whole world. When we talk about 'martial art', we mainly concern about the 'martial' part but always underestimate its 'art' part. Here I say 'most advanced' but it doesn't mean that people who practice tai chi must be the No.1. Here is a good tool prepared for you but it's up to you if you are able to use it well. Anyway, culture surrounding the thing (like here is 'tai chi') decides how far we can go on it.

Tai chi culture has a core which we use the word 'nature' to describe. People come and go, and if we can simply grab a meaningful idea of life attitude some day, that's a metamorphosis. After then, you will know that all the negative attitude such as anger, anxiousness, nervousness and so on are nonsenses.
By practicing tai chi for long, people get slowly see themselves clearly and they observe the outside world by heart. So I always think that tai chi is a 'bible on sport'.
