Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
yuan chia » yunnan china
tan chia » than china, can china, dan china
tan yang » dan yang, tan ying, tan yong
yang lin » yang jin, wang lin, yang li
hong hai » shang hai, zhong tai, hong tan
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) OR (tan chia))) OR (tuan china)) tan yang lin ((dang hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yuan chia) OR (tan chia))) or (tuan china)) tan yang lin ((dang hai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yuan chia) OR (tan chia))) or (tuan china)) tan yang lin ((dang hai) or (hong hai)) ;*.
