Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang hua » yang hui, yang jui, wang hui
ying hua » ming hua, ying zhu, dong hua
rene han » rene ten
xin gong » xian gong, xin tong
gong hui » tong hui, tong shui, wang hui
han xin » hai xin, han min, tan xin

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 di)) ((((yang hua) OR (wang hua))) OR (ying hua)) rene han xin gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang di)) ((((yang hua) OR (wang hua))) or (ying hua)) rene han xin gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang di)) ((((yang hua) OR (wang hua))) or (ying hua)) rene han xin gong hui ;*.
