sang hyup » sang yu
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, kong sar, von sam
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan
yang ji » yang jui, yang jie, yang di
lai » laid

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yan) OR (nan yan)) sang hyup chen ((yang ji) or (yang jin)) ((wong sam) or (wong lai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (nan yan)) sang hyup chen ((yang ji) OR (yang jin)) ((wong sam) OR (wong lai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (nan yan)) sang hyup chen ((yang ji) or (yang jin)) ((wong sam) or (wong lai)) ;*".
