Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
you xian » you liang, you can, you mean
wie eine » wie ein, wie die
yang yun » tang yun, yang yue, yang yang
yang jun » yang jui, pang jun, yang jin
song yun » song byung, chong yun, young yun
wang » wing, wan

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