Perhaps you should try some spelling variations:
chan kang » chung kang, chan eng, chan jan
chan fong » chew fong, chan eng, chan ming
yang yan » yang yang, wang yan, yang yao
yang fan » zhang fan, yang dean, yang yang
yong jui » yang jui, yang jun, yong cai
eang hay » dang hai
kang han » kang chen, kong hang, zhang han

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 ((yang yan) OR (yang fan)) ((chan kang) OR (chan fong)) yong jui ((eang hay) OR (kang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yan) or (yang fan)) ((chan kang) OR (chan fong)) yong jui ((eang hay) or (kang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yan) or (yang fan)) ((chan kang) OR (chan fong)) yong jui ((eang hay) or (kang han)) ;*.
