Perhaps you should try some spelling variations:
wang nan » wang yan, wang ban, wang dan
yan chia » tan chia, can china, dan china
chia tan » chia lan, chen tan, chia wen
tan yong » tan hong, tan kong, tan yang
yong lin » yang lin, song lina, yong kim
zong hai » dang hai, zong he
long han » long chain, long thanh, long haul
hong hai » shang hai, zhong tai, dang hai
nan yan » nan ya, wang yan, qian yan

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