Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang hua » wang hua, yang hui, ying hua
ming hua » ying hua, ming hung, wang hua
rene ten » nine ten
min tong » min hong, xin tong, minh cong
tong hui » wang hui
yang xi » yang di, yang yi, 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 xi)) ((yang hua) OR (ming hua)) ((rene han) OR (rene ten)) min tong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang xi)) ((yang hua) or (ming hua)) ((rene han) OR (rene ten)) min tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang xi)) ((yang hua) or (ming hua)) ((rene han) OR (rene ten)) min tong hui ;*.
