Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
eine yang » eine lange, yin yang, ying yang
hyun song » yun song, kyu song
wie eine » wie ein, wie die
jun song » jin song, yun song, john song
wang » wing, lang

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