Perhaps you should try some spelling variations:
hyung kim » yong kim
wang nan » wang yan, wang ban, wang yang
wang dan » wang yan, wang ban, wang yidan
yan huan » yan guan, yan yuan, tan hua
huan jie » ruan ji
ying kim » yong kim, ying jin, kang kim
wong sam » wong sau, wong lai, kong sar

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 huan jie ((ying kim) OR (hyung kim)) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang nan) OR (wang dan)) yan huan jie ((ying kim) or (hyung kim)) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang nan) OR (wang dan)) yan huan jie ((ying kim) or (hyung kim)) wong sam ;*.
