Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
guan chia » tuan china, tan chia
lang yan » wang yan, wang yang, zhang yan
tan yang » dan yang, tan ying, tan yong
zong hai » hong hai, dang hai, long han
yang li » yang lin, yang di, yang xi
li zong » lin zong, li cong, li rong

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: lang yan ((guan chia) OR (wuhan china)) tan yang li zong hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((guan chia) or (wuhan china)) tan yang li zong hai ;*.
