Perhaps you should try some spelling variations:
dung sheng » dong sheng, fang sheng, bing sheng
than done » than one, than money
wing yan » wang yan, wing ian, wing tan
lang yan » wang yan, wang yang, zhang yan
yang hui » yang jui, wang hui, yang muxi
done sin » dong sin, done using, done so
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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: ((wing yan) OR (lang yan)) ((((yang hui) OR (yang xi))) OR (yang yi)) dung sheng than done sin ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (lang yan)) ((((yang hui) or (yang xi))) or (yang yi)) dung sheng than done sin ;*.
