Perhaps you should try some spelling variations:
othman tan » rahman tan
wang yang » wang yan, wang liang, wang yanling
ka othman » hj othman
tan ying » fan ying, ran ying, tan yang
ying jun » yang jun, ying jin, yang jui
hong hai » shang hai, zhong tai, hong tan
yang ka » yang fan, yang yao

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ka othman tan ying jun ((hong hai) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ka othman tan ying jun ((hong hai) or (dang hai)) ;*.
