Perhaps you should try some spelling variations:
sang hyup » sang yu
hyup chen » yu chen, hua chen, yun chen
wong laid » wong lai, kong land
wing yan » wang yan, wing ian, wing tan
yan sang » yan wang, yang yang, yan liang
yang jui » yang judy, yang di, yang yi
yang jun » pang jun, yang jin, yang judy
yang xi » yang di, yang yi

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: wing yan sang hyup chen ((((yang jui) OR (yang jun))) OR (yang xi)) ((kong sar) OR (wong laid)) ;~.
• Adding a wildcard symbol may retrieve word variants: wing yan sang hyup chen ((((yang jui) or (yang jun))) or (yang xi)) ((kong sar) or (wong laid)) ;*.
