Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
jong minh » gong min, song min, song ming
congo shu » cong shu
yang jui » yang judy, yang di, yang xi
jong min » gong min, song min, song ming
wan yan » wang yan, nan yan, wai yan
yang yi » yang di, yang xi

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 ((yang jui) or (yang yi)) l ((((jong minh) OR (jong min))) or (sang minh)) congo shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((yang jui) OR (yang yi)) l ((((jong minh) OR (jong min))) OR (sang minh)) congo shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang jui) or (yang yi)) l ((((jong minh) OR (jong min))) or (sang minh)) congo shu ;*".
