Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
juan rene » juan meng, juan rana
sang minh » kang minah, anh minh, song min
hong shu » cong shu, tong shui, wong shiu
yang yi » yang di, yang jui
ya juan » y juan, san juan, roa juan
yang li » yang lin, yang di, tang li
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 yang) OR (yang yi)) ya juan rene ((((yang li) OR (yang xi))) OR (sang minh)) hong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang yi)) ya juan rene ((((yang li) or (yang xi))) or (sang minh)) hong shu ;*.
