chen chang » chen chung, chin chang, when change
shen chang » when change, chin chang, han chang
fang zhen » fang sheng, wang zheng, fang zhou
wang yong » wang yang, wang hyoung, wang yan
quan yi » qian yi
yong yu » hong yu, rong yu, young yun

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: ((tang zheng) OR (fang zhen)) quan yi ((chen chang) OR (shen chang)) wang yong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tang zheng) OR (fang zhen)) quan yi ((chen chang) or (shen chang)) wang yong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((tang zheng) OR (fang zhen)) quan yi ((chen chang) or (shen chang)) wang yong yu ;*.
