Perhaps you should try some spelling variations:
othman tan » rahman tan
dong yang » dong hoang, wang yang, yang yang
ka othman » hj othman
shang hai » shang kai, chang ha, zhang han
tan ying » fan ying, ran ying, tan yang
ying jun » yang jun, ying jin, yang jui
hong hai » zhong tai, hong tan, hong a
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: dong yang ka othman tan ying jun ((((hong hai) OR (shang hai))) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ka othman tan ying jun ((((hong hai) OR (shang hai))) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang ka othman tan ying jun ((((hong hai) OR (shang hai))) or (dang hai)) ;*.
