Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
yang yang » wang yang, wang yan
yang jie » yang jin, yang di, yang jui
long shu » cong shu, tong shui, long du
hua pei » hua wei
yang yi » yang di, yang xi, 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: ((((yan liang) OR (you liang))) OR (yang yang)) wang hua pei ((yang yi) OR (yang jie)) long shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yan liang) or (you liang))) or (yang yang)) wang hua pei ((yang yi) or (yang jie)) long shu ;*.
