First of all, I would like to emphasize one thing: Kung Fu ≠ Fighting Qigong performances, set competitions, etc. are also Kung Fu, and are an important part of Chinese martial arts. You can't trivialize them by saying they're not fighting and can't be fought. I've seen Chinese kung fu masters, there are the wu xing in Peking Opera. Those martial arts passages in "The Palace of Heaven" were a delight to watch when I was a child, and I can't forget them now. I have also seen the National Games routine competition, long fist, south fist, south stick ... that kind of beauty and tension of the performance is really eye-opening to me. These are real kung fu masters. However, when you talk about the fighting part, it's Sanshou, Chinese wrestling. Other than that, truth be told there is none. Any fighting art that can be fought has a specific form of actual combat confrontation.
Taekwondo, Judo, Wrestling, Boxing are all already Olympic sports, Muay Thai has tens of thousands of fights a year, Karate has a World Championship every two years. What about Chinese Kung Fu? Probably all the cases of actual combat that can be thought of and made up don't have as many fights as Muay Thai has in a day. From Vale Tudo in the 1920's, to the introduction of Jiu-Jitsu to Brazil, to the rise of stand-up combat, to the first UFC... the world of combat has been competing with each other for nearly a hundred years, and Chinese Kung Fu has been a part of it? Yes, but we don't recognize the kung fu fought by those foreigners. A lot of people talk about Bruce Lee. Bruce Lee's path went one step further and that was mixed martial arts. Now that the traditional martial arts world and MMA are at loggerheads, who has the nerve to talk about Bruce Lee? Chinese Kung Fu has never been short of masters, they are in the National Games, in the sparring ring, in the wrestling (and also in the performance of martial arts comedy), on the stage of Peking Opera... I know what you have in your head to think of a master of Kung Fu. But that really doesn't exist.
