Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
shang hai » shang kai, dang hai, chang ha
wang nan » wang yan, wang ban, wang dan
ya ching » a china, la chine, te ching
mo ching » mao china, goh ching, te ching
yong lin » yang lin, song lina, yong kim
zong hai » hong hai, dang hai, zong he
long han » long chain, long thanh, long haul

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