Perhaps you should try some spelling variations:
rene sang » lee sang
sang minh » kang minah, anh minh, song min
hua rene » hua ren, juan rene
wong sau » wong sam, wong siu, wong shiu
hong ghi » zhong zhi, hong g, hong hai
yang yi » yang di, yang jui
yang xi » yang di, yang jui

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yi) OR (yang xi)) ya hua rene sang minh ((wong sau) OR (hong ghi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yi) OR (yang xi)) ya hua rene sang minh ((wong sau) or (hong ghi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yi) OR (yang xi)) ya hua rene sang minh ((wong sau) or (hong ghi)) ;*.
