Perhaps you should try some spelling variations:
wuhan china » yunnan china
tuan china » can china, taiwan china, yunnan china
yang liang » wang liang, yan liang, yang yang
long tan » hong tan, long han, long thanh
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
best » west

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: long tan ((tuan china) OR (wuhan china)) (rest OR best) ((yang jin) OR (yang liang)) wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long tan ((tuan china) OR (wuhan china)) (rest or best) ((yang jin) or (yang liang)) wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: long tan ((tuan china) OR (wuhan china)) (rest or best) ((yang jin) or (yang liang)) wong yue ;*.
