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
zhong yun » chong yun, zhong yong, chang yun
you xian » you liang, you can, you mean
wie eine » wie ein, wie die
yang yu » yang yue, yang yun, yang yi
hong yu » wong yue

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yang yang) or (yan liang))) or (you xian)) wie eine yang yu ((zhong yun) OR (hong yu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang yang) OR (yan liang))) OR (you xian)) wie eine yang yu ((zhong yun) OR (hong yu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yang) or (yan liang))) or (you xian)) wie eine yang yu ((zhong yun) OR (hong yu)) ;*".
