Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
yuan chia » tan chia, yunnan china
tan yang » dan yang, tan ying, tan yong
yang lin » yang jin, wang lin, yang li
zong hai » dang hai, long han, zong he
hong hai » shang hai, zhong tai, dang hai
wang » wing, wan

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 OR lang) yan ((yuan chia) OR (tuan china)) tan yang lin ((zong hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR lang) yan ((yuan chia) or (tuan china)) tan yang lin ((zong hai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR lang) yan ((yuan chia) or (tuan china)) tan yang lin ((zong hai) or (hong hai)) ;*.
