Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
sang minh » kang minah, anh minh, song min
minh hong » minh cong, min hong, linh hoang
hua rene » hua ren
yang jui » yang judy, yang di, yang yi
hong ghi » zhong zhi, hong g, hong hai
yang ka » yang fan, yang yao
yang xi » yang di, yang yi

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 ka) OR (((yang xi) OR (yang jui))))ng ya ((hua rene) OR (juan rene)) sang minh hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ka) or (((yang xi) or (yang jui))))ng ya ((hua rene) OR (juan rene)) sang minh hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang ka) or (((yang xi) or (yang jui))))ng ya ((hua rene) OR (juan rene)) sang minh hong ghi ;*.
