“Real Kung Fu”?
This is not a new topic. It’s been discussed previously on other forums through the years. However, I understand what you’re getting at.
A lot of kung fu styles share similar basic punches & kicks so, using them in sparring, they might slightly resemble “kickboxers” but not exactly. That doesn’t necessarily mean that they’re not using their kung fu techniques; just some of them, and not the ones YOU specifically want to see.
For sport (i.e. sparring matches), there have to be rules to protect the fighters (e.g. no eye gouging; no fish hooking; no strikes to the groin; no strikes to the back of the neck; etc.). That applies not only to competitive kung fu, but to most other competitive martial arts as well (e.g. MMA, MT, TKD, Karate, Boxing, Wrestling, Hockey :eek:).
It seems that you’re probably referring to the more exotic-looking, open-handed techniques & acrobatics, somewhat similar to what Oso implied with reference to Shaw Bros-style cinematic kung fu fighting.
Thing is, if fighters start using such techniques (e.g. fu jow, biu jee) to the eyes, throats, groin and other sensitive areas, you’ll end up with more blind/deaf/castrated/otherwise maimed participants who won’t be able to fight for very long & will have a hard time paying their bills and providing for their families, blah blah blah. Yeah, practice those open-hand techniques, but you’re probably best to save the actual applications for street / self-defence situations, not for friendly sport.
You don’t need to see someone finger jab someone in the eye or crush someone’s larynx in a sparring match in order for you to say that you’ve finally witnessed someone using their kung fu, and that kung fu actually works, do you?
If so, you should just go to the local mo kwoon and pick a real fight (not a sparring match) with someone there to possibly witness real kung fu first-hand without bothering with those impersonal YouTube clips! lol j/k No, on second thought, don’t do that! 
G’night…
