Before I started training Chu Sau Lei I already practiced Wing Chun and other Chinese Martial Arts.  What I like about training Chu Sau Lei Wing Chun is:

We learn traditional Chinese martial art but we are able to apply it in a modern context.
We learn the traditional Wing Chun forms but we also use modern tools and training concepts.
These are important concepts and training methods  that most other Chinese martial arts has failed to adept to and comprehend and has  made CSL Wing Chun able to hold up in todays’ context
