Perhaps you should try some spelling variations:
yan chia » tan chia, can china, dan china
chia tan » chia lan, chen tan, chia wen
tan kong » tan hong
kong lin » kong lyn, kong land, song lina
long han » long chain, long thanh, long haul
hong hai » shang hai, zhong tai, hong tan
yan yan » yan yuan, nan yan, yang yang
wang » wing, wan, lang

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 yan yan chia tan kong lin ((((long han) OR (hong hai))) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan yan chia tan kong lin ((((long han) or (hong hai))) or (dang hai)) ;*.
