Buakaw is such a cool guy. This Chinese dude can afford to get into a ring with Buakaw, so who cares, if it's not a serious fight? It was as serious as the this guy could take it. He made memories that he will keep for the rest of his life. He's probably a huge fan. Most professional fighters wouldn't even take the little guy seriously and humiliate him in the ring. But Buakaw doesn't roll like that. Respect.
P.S. I do think the Chinese guy could've had more fun, had he been more conditioned. But he doesn't fight for a living. Who has time to train like pros do?
