Perhaps you should try some spelling variations:
hyoung kim » yong kim, hyoung il
hyung kim » yong kim
sang minh » kang minah, anh minh, song min
yan minh » tuan minh, yang mind, yuan ming
hua ren » hua chen
von seo » von see, von seu, von sex
wang » wing, wan, lang
hong » long

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 ((hyoung kim) OR (hyung kim)) hua ren ((yan minh) OR (sang minh)) ((von seo) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hyoung kim) OR (hyung kim)) hua ren ((yan minh) or (sang minh)) ((von seo) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((hyoung kim) OR (hyung kim)) hua ren ((yan minh) or (sang minh)) ((von seo) or (hong seo)) ;*.
