Perhaps you should try some spelling variations:
chang ch'un » chang chen, chang chuan, chang hsun
tang ping » ting ping, zhang ping, dong ping
ping wang » ping pong, hong wang
guan yang » huang yang, dan yang, tan yang
yan guan » gan guan, yan yuan, yang guang
eang hay » kang han
yang xi » yang di, yang yi, yang jui

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 ping wang yan guan yang xi ((((eang hay) OR (dang hai))) OR (chang ch'un)) ;~.
• Adding a wildcard symbol may retrieve word variants: tang ping wang yan guan yang xi ((((eang hay) or (dang hai))) or (chang ch'un)) ;*.
