Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
duong anh » dang anh, duong van, trong anh
yang jui » yang judy, yang di, yang yi
zhuo lee » choo lee
cong seo » hong seo, cong shu, cong sun
yang xi » yang di, yang yi
hua lee » hwan lee, phua lye

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

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