People pay attention to Ip Man mainly because of the film series, and his disciples Bruce Lee and Bruce Lee are famous all over the world. He is so famous because he invented Jeet Kune Do. The emergence of Jeet Kune Do can be said to have changed the martial arts all over the world and brought great changes to martial arts. Because this kind of boxing is very simple and fast, it combines all kinds of boxing methods and is not limited to the only form.
The key point of Jeet Kune Do is the change of thought, which introduces Yin and Yang and five elements, and all tangible attacks are invisible. In the fight with others, moves can be easily resolved. Ip Man is a master of Wulin. His wing chun boxing is famous at home and abroad, and it is also famous internationally. His disciples mastered his boxing and spread it all over the world, letting the world know about China Kung Fu. I'm sure everyone is impressed with the series of films by Ip Man, and one of the ending clips is that Bruce Lee worships Ip Man as his teacher.
Actually, Bruce Lee studied with Ip Man for a while, and then he went to America. Perhaps from the perspective of passing boxing, IP Man doesn't like Jeet Kune Do created by Bruce Lee in such a deviant way. However, if this is the reason why IP Man chased Li, it would be a bit too much. Because the way of practicing martial arts is not only to improve one's own strength, but more importantly, to respect the teacher and live in harmony with others. It has been decades since it happened, and no one knows, so we have to wait for historians to study it.
