Perhaps you should try some spelling variations:
using bank » housing bank
zhang jia » zhang jian, zhang jing, zhang tian
zhang jin » zhang jian, zhang jing, shang jin
yang yang » wang yang, wang yan
fang hoi » fang zhou, bang how, dong hoi
how hai » how has, how ai, how have
how hci » how heis

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: ((zhang jia) OR (zhang jin)) fang hoi ((using bank) OR (yang yang)) aid ((how hai) OR (how hci)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang jia) OR (zhang jin)) fang hoi ((using bank) or (yang yang)) aid ((how hai) or (how hci)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang jia) OR (zhang jin)) fang hoi ((using bank) or (yang yang)) aid ((how hai) or (how hci)) ;*.
