Perhaps you should try some spelling variations:
case dann » case anna, case anne, case das
yan liang » yang liang, wang liang, you liang
one case » some case, one class, one phase
dann bin » dong bin
yong jin » yang jin, ying jin, song jin
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi

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 bin we ((((yong jin) OR (yan liang))) OR (yang jie)) ((yang jui) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case dann bin we ((((yong jin) or (yan liang))) or (yang jie)) ((yang jui) or (yang di)) ;*.
