Perhaps you should try some spelling variations:
one class » one case
class way » class war, class why, class what
yang jie » yang jin, yang xi, yang yi
dong bin » dong sin, dong di, dann bin
yang jui » yang judy, yang xi, yang yi
wong yue » wang yue, hong yu
way goh » way goes, way john

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 class way goh chor ((((yang jie) OR (dong bin))) OR (yang jui)) ((wong yue) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one class way goh chor ((((yang jie) or (dong bin))) or (yang jui)) ((wong yue) or (yang di)) ;*.
