Perhaps you should try some spelling variations:
othman tan » rahman tan
dong yang » dong hoang, wang yang, yang yang
ka othman » hj othman
chang mae » chang ha, changes made
tan ying » fan ying, ran ying, tan yang
ying jie » yang jie, ying jin, jing ji
hong hai » shang hai, zhong tai, dang hai
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 jie ((hong hai) OR (chang mae)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang ka othman tan ying jie ((hong hai) or (chang mae)) ;*.
