Perhaps you should try some spelling variations:
hyoung kong » hong kong
wan hyoung » wang hyoung, man houng, min hyoung
wong shiu » wong siu, cong shu, song shin
wong sam » wong sau, wong lai, kong sar
den gan » den gang, den grad, den game
hong yu » wong yue
kong a » kong _, kong sar, kong yam
a den » _ den, a der, a des

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: wan hyoung kong a den gan li ((((wong sam) OR (wong shiu))) OR (hong yu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung kong a den gan li ((((wong sam) or (wong shiu))) or (hong yu)) ;*.
