Practicing wing chun boxing will shorten the life span, because it will cause the practitioners to lose their vitality and is not suitable for health preservation. Wing Chun is superior to other martial arts in many aspects, such as speed, skill, relay and impact. However, its rapid and frequent short-term burst of strength can easily lead to the loss of vitality of practitioners, thus shortening their life span. Excessive short-term strength will cause overdraft to the body and wear to the root bones, so we should pay attention to the problem of practice. This answer is for reference only. Don't be blindly superstitious.
