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

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