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