Perhaps you should try some spelling variations:
housing bank » housing bonds, housing a
yang hoi » yang di, yang jui, yang xi
yang hui » yang jui, wang hui, yang muxi
bank aid » band aid, bank card, bank adb
wan yan » wang yan, nan yan, wai yan
how g » how _, how a, how e
how i » how _, how a

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: wan yan ((yang hoi) OR (yang hui)) housing bank aid ((how g) OR (how i)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((yang hoi) or (yang hui)) housing bank aid ((how g) or (how i)) ;*.
