Perhaps you should try some spelling variations:
yang jui » yang judy, yang di, yang yi
kim song » kim young, kim eung
min cong » minh cong, min hong, min jeong
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan
yang xi » yang di, yang yi
li song » li cong, li rong, jie song

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)) ((yang jui) or (yang xi)) ((li song) OR (kim song)) min cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (nan yan)) ((yang jui) OR (yang xi)) ((li song) OR (kim song)) min cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (nan yan)) ((yang jui) or (yang xi)) ((li song) OR (kim song)) min cong shu ;*".
