kyoung yun » young yun, kyoung yang, young eun
hyoung gun » young eun
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
chang jun » chang jui, chang yun, zhang jun
wie ying » wie fing, wie ein, wie eine

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