Where did Jackie Chan get his stunt-scenes ideas from?

There is no doubt that Jackie Chan is one of the most famous Asian actors, and perhaps the most in the world. His action films were distinguished by a distinctive character, especially with his comedy, but what distinguishes Jackie Chan is his stunt scenes which he did himself, in more than 200 films, these scenes caused him a lot of fractures and wounds, but he was not the first actor in history to perform his own stunt scenes, he was preceded by Buster Keaton, who may be the first actor in history to perform his stunt scenes himself, it is noted that many of the stunt scenes that Jackie Chan performed were inspired by the scenes performed by Buster, and perhaps the most famous of them is the clock scene that Jackie Chan performed in the movie Project A.
