Perhaps you should try some spelling variations:
yan guan » gan guan, yang guang, yihan guan
yan yuan » fang yuan, yan clan, yan kun
yang kim » yong kim, kang kim, hyung kim
kim song » kim young, kim eung
song sau » wong sau, kong sar, song pae
wan yan » wang yan, wai yan, wang yang
nan yan » wang yan, qian yan, dan yang
nan ya » nana yaa

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: ((wan yan) OR (nan ya)) ((((yan yuan) OR (nan yan))) OR (yan guan)) rene yang kim song sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (nan ya)) ((((yan yuan) OR (nan yan))) or (yan guan)) rene yang kim song sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (nan ya)) ((((yan yuan) OR (nan yan))) or (yan guan)) rene yang kim song sau ;*.
