Perhaps you should try some spelling variations:
lang yang » yang yang, lang lang, ylang ylang
wang yang » wang yan, wang liang, wang yanling
sang minh » kang minah, anh minh, song min
minh wong » minh cong, min hong, ming kong
yang jui » yang judy, yang di, yang yi
wong siu » wong shiu, kong siu, wong sau
yang xi » yang di, yang yi
li sang » le sang, li gang, li san

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((lang yang) OR (wang yang)) ((yang jui) or (yang xi)) li sang minh wong siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yang) OR (wang yang)) ((yang jui) OR (yang xi)) li sang minh wong siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yang) OR (wang yang)) ((yang jui) or (yang xi)) li sang minh wong siu ;*".
