Perhaps you should try some spelling variations:
wang nan » wang yan, wang ban, wang yang
wang dan » wang yan, wang ban, wang yidan
yan chia » tan chia, can china, dan china
chia wen » china won, ching wen, asia wen
yong lin » song lina, yong kim, dong liu
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 nan) OR (wang dan)) yan chia wen ((yong lin) OR (yang lin)) ((zong hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang nan) OR (wang dan)) yan chia wen ((yong lin) or (yang lin)) ((zong hai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang nan) OR (wang dan)) yan chia wen ((yong lin) or (yang lin)) ((zong hai) or (hong hai)) ;*.
