National Geographic, Discovery Channel, etc...just a bunch of *****s by different names. There are good and legit programs there, but there are plenty of stupid, fake crap too. They contract out and/or buy these documentary films and stick their channel label on it. They're not experts on everything, so plenty of BS gets through w/o much research done to verify. They don't know squat about fighting.
The Amazing Randi has a standing $1,000,000 challenge for anyone, anywhere to prove such BS exists. He'd even go to China. No one has taken his money yet for over 20 years. He's a master magician & illusionist. BS artists can't fool him. Fooling people is his life.

Think some poor Qi Gong whatever slobs in China can't use US$1,000,000 EACH? Ever since the Chinese govt' reopened The Shaolin Temple like a Chinese Disneyland, that place has been whoring for tourism dollars selling trinkets, fake monks putting on shows and Shaolin Kung-Fu lessons to fatboys all over the world for nearly 10 years now. China also exports a bunch of Wu-Shu players dressed up as Shaolin Monks, worldwide, to spread Kung-Fu + Buhdism because it's big money, despite Marxists are against religions.
Here's a skinny little kid who looks like he can't even do 10 pushups, bending spears with his throat:

You must be new to the martial arts to think that these tricks are real. It's ok. I used to think they're real too from watching movies and even documentaries. Just like how people who've never really fought before, thinks that being a Marine or Navy Seal, etc. automatically makes someone great at hand to hand fighting. It's only after I started fighting in the ring and trying to knock people out during sparring was when I realized what's BS and what's not (most of the time anyway).
