Perhaps you should try some spelling variations:
kang young » wang hyoung
than chae » than change, than ch2o, than coal
chen ping » chen rong, chen yang, chen wang
wong shiu » cong shu, song shin, wong sau
yan than » van thanh, yan zhang, yan clan
yun chen » yung chen, yu chen, yuan cheng
ping lin » ling li, ping jia, ping yi
wong siu » kong siu, wong sau, wong siew

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: yan than chae yun chen ping lin ((((wong siu) OR (wong shiu))) OR (kang young)) ;~.
• Adding a wildcard symbol may retrieve word variants: yan than chae yun chen ping lin ((((wong siu) or (wong shiu))) or (kang young)) ;*.
