Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang lin » yang jin, wang lin, yang liang
yang jie » yang jin, yang di, yang jui
song tin » song jin, song min, song shin
hong sau » hong paul, kong sar, hong seo
wong sau » wong sam, wong siu, wong shiu
yang li » yang di, yang xi, yang yi
xu song » kyu song, yun song

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 ((((yang lin) OR (yang li))) OR (yang jie)) xu song tin ((hong sau) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((((yang lin) or (yang li))) or (yang jie)) xu song tin ((hong sau) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yang lin) or (yang li))) or (yang jie)) xu song tin ((hong sau) OR (wong sau)) ;*.
