Perhaps you should try some spelling variations:
wang yang » wang yan, wang yanling
tan chia » tuan china, than china, can china
chia wen » china won, ching wen, asia wen
wen yang » wei yang, wen wang, chen yang
yang lin » yang jin, wang lin, yang li
zong hai » dang hai, long han, zong he
hong hai » shang hai, zhong tai, dang hai

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 liang) OR (wang yang)) tan chia wen yang lin ((zong hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yang)) tan chia wen yang lin ((zong hai) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yang)) tan chia wen yang lin ((zong hai) OR (hong hai)) ;*.
