IIRC Baoligao is the 2003 Sandawang champion. I think he beat Liu Hailong that year to become the champ since Hailong was 2002 champ. He is actually ethnic mongolian hence the non-chinese name. Unlike most sanda fighters, he has a very hard hitting direct style. Also seemed to have a strong if basic clinch + knee game and strong throws (not surprisingly since he's mongolian).
I don't know much about Sitichok so if anyone else have more info please post. This event took place in Bangkok, Thailand. The Thais do not seemed like second rate guys. Baowee and Samkor fought in this event and both lost by points. Baowee actually got cut by an elbow in this match.
