Personal opinion: First of all, apprentices are widely taught, which forms a certain foundation among the masses and is recognized in a certain area. Since it is a new martial art, it must have its own characteristics, which is different from the martial arts circulating today. More importantly, it is best to form a certain martial arts theory and raise this martial arts to the theoretical level. Increase publicity, which may require the support of the government or enterprises to be more powerful. Under normal circumstances, after spreading in a certain area, distinctive interests will naturally spread. For example, Tai Ji Chuan is the only sport without any harm, so it naturally spreads widely. I think the spread of Jeet Kune Do is mainly due to movies.
