Perhaps you should try some spelling variations:
hyung kim » yong kim
chai wang » chen wang
wang yang » wang yan, wang liang, wang yanling
hong than » hong tan, long thanh
yang kim » yong kim, kang kim, yang di
yang jin » yang jie, yang jun, ying jin
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: yang ((yang kim) OR (hyung kim)) chai wang yang jin ((hong hai) OR (hong than)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yang kim) OR (hyung kim)) chai wang yang jin ((hong hai) or (hong than)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((yang kim) OR (hyung kim)) chai wang yang jin ((hong hai) or (hong than)) ;*.
