Perhaps you should try some spelling variations:
wang yuhan » wang luhang, wang yan, wang yidan
yuhan kang » yuan kang, chan kang, yuhuan huang
ahsan syed » khan syed
chan fung » chan fong, can fund, chan eng
can she » can see, can shape, can save
chung h » chun h, chung _, chung chi
hee » here, chee

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