Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, hwang byoung
kang young » wang hyoung
das region » dam region, its region, das regime
region gan » region a, region al, region gandja
kong das » kong maps, kong sar, kong yam
wong sau » wong sam, wong siu, wong shiu
hong yu » wong yue

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: ((lang hyoung) OR (kang young)) kong das region gan li ((wong sau) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang hyoung) OR (kang young)) kong das region gan li ((wong sau) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang hyoung) OR (kang young)) kong das region gan li ((wong sau) or (hong yu)) ;*.
