Apart from Hongkong, Wing Chun is not popular in China, very few people know it before Movie called Yip Man acted by Kungfu Star Donnie Yen(Zen Zi Dan)who is my favourite Kungfu Star, another is Jet Li. Even though Yip Man film was hot then, in person, I still think it is just film itself, not bring much impact on people who want to start learning wing chun, so, that is the acutal situation in China now about Wing Chun development. Another question is here very few Sifu open schools to develop wing chun, But if you want to find someone, I can recommend some for you if you temporary live in China for working since many people asked about that.
