He is certainly a good shooter... but number 1 in all of China?
Most of, if not all the shots I saw him perform in the videos, I can do... and let me tell you something, I'm not nearly as good of a shot (with rifle or bow) as quite a few guys I know and know of. If they ever decided to use a slingshot I'm sure they'd be better than me with that as well... the USA doesn't have nearly as many people as China and of that number a far less of a percentage actively use slingshots as well compared to China...
So what I'm saying is, it just doesn't seem right that guy could be the number 1 shooter in China... unless those videos aren't really representative of his true skill level.
