Perhaps you should try some spelling variations:
yan chia » tan chia, can china, dan china
tan yong » tan hong, tan kong, tan ying
tan yang » dan yang, tan ying, tao yang
zong hai » dang hai, zong he
long han » long chain, long thanh, long haul
hong hai » shang hai, zhong tai, dang hai
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 yong) OR (tan yang)) lin ((((zong hai) OR (long han))) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yan chia ((tan yong) or (tan yang)) lin ((((zong hai) OR (long han))) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yan chia ((tan yong) or (tan yang)) lin ((((zong hai) OR (long han))) or (hong hai)) ;*.
