Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yan liang » yang liang, wang liang, you liang
yan guan » gan guan, yan yuan, yang guang
tuan hua » tan hua, tuan vu, yuan hui
gong hui » tong hui, tong shui, wang hui
hua pei » hua wei
yang xi » 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 (yan liang))) OR (yan guan)) tuan hua pei ((yang di) OR (yang xi)) gong hui ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (yan liang))) or (yan guan)) tuan hua pei ((yang di) or (yang xi)) gong hui ;*.
