Perhaps you should try some spelling variations:
dong can » dong cao, dong nan, congo can
can bank » bank bank, loan bank, main bank
yang jie » yang jin, yang jui, yang xi
when so » when do, when co, when soft
so ging » so fing
yang yi » yang xi, yang jui
bank 7 » bank _, bank a, bank 4
7 when » 3 when, 4 when

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: dong can bank 7 when so ging ((((wang yan) OR (yang jie))) OR (((yang yi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong can bank 7 when so ging ((((wang yan) or (yang jie))) or (((yang yi) or (yang di)))) ;*.
