Odd Asian Competition Shows

So I was watching one of the Vietnamese channels I pick up on my antenna and came across this singing competition show. But this show is unlike any show I've seen from the west. This show has the contestants sing under random stressful situations.

So in this picture, a couple guys are singing while strapped to these spinning wheels. The wheels spinning isn't the big deal, it's the guy throwing knives at the balloons on the spinning wheels which makes it interesting.

This girl meanwhile is singing while being dangled over a water tank full of snakes.
