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
yan sang » yan wang, yang yang, yan liang
yang din » yang jin, yang lin, yang dean
nan yan » nan ya, wang yan, qian yan
yang xi » yang yi, yang jui

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