Perhaps you should try some spelling variations:
tuan china » wuhan china, taiwan china, yunnan china
guan chia » tan chia
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan kong, tan ying
hong hai » shang hai, zhong tai, dang hai
li hong » le hong, li cong, li rong
wang » wing, wan, lang

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