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
hong ghi » zhong zhi, hong g, hong hai
wong yue » wang yue
yan li » yang li, yuan li, gan li
li hua » li hui, lu hua
wang » wing, wan, lang

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: wang yan li hua rene sang minh ((hong ghi) OR (((hong yu) OR (wong yue)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan li hua rene sang minh ((hong ghi) or (((hong yu) OR (wong yue)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan li hua rene sang minh ((hong ghi) or (((hong yu) OR (wong yue)))) ;*.
