Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yan liang » yang liang, wang liang, you liang
eine yang » eine lange, yin yang, ying yang
hua zhong » hu hong, wu zhong, yu zhong
zhong yun » chong yun, zhong yong, hong yu
you xian » you liang, you mean
wie eine » wie ein, wie die
yang hua » wang hua, yang hui, ying hua

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