Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
you liang » you liangzhi
sind yang » rindu yang, yin yang, ying yang
yan wang » yuan wang, qian wang, yan liang
you xian » you can, you mean
wie sind » sie sind, wie ein, wie sich
yi zheng » yu zheng, qin zheng, yi chen
zheng yu » zheng liu, heng fu, cheng lu
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 ((((yang yang) OR (yan wang))) OR (((you liang) OR (you xian)))) wie sind yang yi zheng yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yang) or (yan wang))) or (((you liang) OR (you xian)))) wie sind yang yi zheng yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang yang) or (yan wang))) or (((you liang) OR (you xian)))) wie sind yang yi zheng yu ;*.
