Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
guan chia » tan chia
dan yang » daun yang, tan yang, wang yang
yang lin » yang jin, wang lin, yang li
zong hai » hong hai, dang hai, zong he
long han » long chain, long thanh, long haul
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 ((guan chia) OR (tuan china)) dan yang lin ((zong hai) OR (long han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan ((guan chia) OR (tuan china)) dan yang lin ((zong hai) or (long han)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan ((guan chia) OR (tuan china)) dan yang lin ((zong hai) or (long han)) ;*.
