Hey! You're completely missing out Choy Lay Fut. I'm quite sure Tai Chi is the most widely spread and known Chinese martial art out there. One of the distinct reasons for its fame is that it is not only favoured by its competency in combat, but it also serves as an excellent way to exercise the body for health benefits. Not involving any physically demanding moves, such as aerial jumps and tornado kicks, it is suitable for all ages. Apart from Tai Chi, I would say that contemporary wushu is increasingly gaining popularity among the young people, but perhaps the traditional arts such as Wing Chun and Choy Lay Fut are still governing the external scene in the west. It depends a lot where you are.
