Perhaps you should try some spelling variations:
how dong » how doing, how long, how hong
dong bin » dong sin, dong di, dann bin
bin when » win when, can when, bin we
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang xi
when so » when do, when co, when soft
so ging » so fing
yang yi » yang xi

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 how dong bin when so ging ((yang jun) OR (((yang jui) OR (((yang yi) OR (yang di)))))) ;~.
• Adding a wildcard symbol may retrieve word variants: one how dong bin when so ging ((yang jun) or (((yang jui) or (((yang yi) or (yang di)))))) ;*.
