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