Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
you liang » you xian, you liangzhi
sind yang » rindu yang, yin yang, ying yang
yan wang » yuan wang, qian wang, yan liang
wie sind » sie sind, wie ein, wie sich
yi zheng » qin zheng, yi chen, _ zheng
yu zheng » yu cheng, yu zhong, _ zheng

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)) wie sind yang ((yi zheng) OR (yu zheng)) yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yang) or (yan wang))) or (you liang)) wie sind yang ((yi zheng) OR (yu zheng)) yun ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang yang) or (yan wang))) or (you liang)) wie sind yang ((yi zheng) OR (yu zheng)) yun ;*.
