Perhaps you should try some spelling variations:
case dann » case anna, case anne, case das
dann doch » kann doch, dann auch, dann nich
doch chen » goh chen, don chen
dong ping » dong sin, dong bin, dong jung
one case » some case, one class, one phase
yang jui » yang judy, yang xi, yang yi
yang yue » wang yue, yang yun, yang yi
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 dann doch chen ((((jing ji) OR (dong ping))) OR (yang jui)) ((yang yue) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case dann doch chen ((((jing ji) or (dong ping))) or (yang jui)) ((yang yue) or (yang di)) ;*.
