yang yang » wang yang, wang yan
chen chih » chen chiu, chen zhi, chou chih
chih sing » chih p'ing, chih hang, chih yung
sing dong » sing kong, jeng dong, shin dong
dong sind » dong sin, dong bin, dong ping
quan guo » quan guan

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: lang ((((fang yuan) OR (yang yang))) OR (quan guo)) yi chen chih sing dong sind ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((fang yuan) or (yang yang))) or (quan guo)) yi chen chih sing dong sind ;*.
