Perhaps you should try some spelling variations:
case anna » case anne
anna doch » dann doch, kann doch
doch chen » goh chen, don chen
one case » some case, one class, one phase
dong bin » dong sin, dong di, dann bin
yang jui » yang judy, yang xi, yang yi
yang yun » yang jun, tang yun, yang yue
jing ji » ying jin

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: one case anna doch chen ((((jing ji) OR (dong bin))) OR (yang jui)) ((yang yun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case anna doch chen ((((jing ji) or (dong bin))) or (yang jui)) ((yang yun) or (yang di)) ;*.
