Perhaps you should try some spelling variations:
wuhan china » yunnan china
than china » han china, can china, dan china
tuan china » can china, taiwan china, yunnan china
ban yang » dan yang, tan yang, wang yang
yang lin » yang jin, wang lin, yang li
lin zong » lin ling, lin meng
zong hai » hong hai, dang hai, long han
wan yan » wang yan, nan yan, wai yan

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: wan yan ((((than china) OR (tuan china))) OR (wuhan china)) ban yang lin zong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((than china) OR (tuan china))) or (wuhan china)) ban yang lin zong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((((than china) OR (tuan china))) or (wuhan china)) ban yang lin zong hai ;*.
