Perhaps you should try some spelling variations:
using census » housing census, using cross, housing censuses
liang wang » liang dan, liang tan, liang ying
from using » from being
wang yang » wang yan, wang liang, wang yanling
yang from » tang from, kong from
shang hai » shang kai, dang hai, chang ha
hong jong » hong kong
census a » census _, censuses a, versus 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: liang wang yang from using census a ((shang hai) OR (hong jong)) ;~.
• Adding a wildcard symbol may retrieve word variants: liang wang yang from using census a ((shang hai) or (hong jong)) ;*.
