Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
young yun » kyoung yun, young eun, young young
you xian » you liang, you can, you mean
wie ying » wie fing, wie ein, wie eine
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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