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