Perhaps you should try some spelling variations:
housing bonds » housing costs
housing bank » housing a
wang yong » wang yang, wang hyoung, wang yan
yang dali » yang di, yang all, yang li
bang dai » zhang dai
kong » long, hong, pong
sar » sara, star, saur

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: wang yong ((yang dali) OR (bang dai)) era ((housing bank) OR (housing bonds)) kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang dali) or (bang dai)) era ((housing bank) OR (housing bonds)) kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang dali) or (bang dai)) era ((housing bank) OR (housing bonds)) kong sar ;*.
