Perhaps you should try some spelling variations:
test housing » cost housing, test using, era housing
yang davis » wang david, yang dali
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
a housing » 4 housing
kong saur » kong sar, kong your, wong sau
kong siu » kong eiu, wong siu, dong sin

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 davis ((test housing) OR (a housing)) a ((kong saur) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang davis ((test housing) or (a housing)) a ((kong saur) OR (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang davis ((test housing) or (a housing)) a ((kong saur) OR (kong siu)) ;*.
