Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan kang » yuan kang
ahsan syed » khan syed
chan fung » can fund, chan eng, chan kang
chan fong » chew fong, chan eng, chan kang
chung chi » chung h
can she » can see, can shape, can save

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 yidan kang ((can she) OR (ahsan syed)) ((chan fung) OR (chan fong)) chung chi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan kang ((can she) or (ahsan syed)) ((chan fung) OR (chan fong)) chung chi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yidan kang ((can she) or (ahsan syed)) ((chan fung) OR (chan fong)) chung chi ;*.
