Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
zheng yun » zheng yu, zheng quan, zheng xuan
yin yang » ying yang, yi yang, yin fang
yi zheng » yu zheng, qin zheng, yi chen
wie yin » wie ein, wie eine, wie sind
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: wang ((((wang yan) OR (yan liang))) OR (you liang)) wie yin yang yi zheng yun ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((wang yan) or (yan liang))) or (you liang)) wie yin yang yi zheng yun ;*.
