Perhaps you should try some spelling variations:
wang liang » wang yang
case dann » case anna, case anne, case das
one case » some case, one class, one phase
dann bin » dong bin
ying jin » jing ji, yang jie
yang jin » yang jie, yang jun, shang jin
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 ((((ying jin) OR (wang liang))) OR (yang jin)) ((yang jui) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case dann bin we ((((ying jin) or (wang liang))) or (yang jin)) ((yang jui) or (yang di)) ;*.
