Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
yang yang » wang yang, wang yan
yulu chen » yu chen
chan ming » kian ming, chan eng, chan fong
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yang ka » yang fan, yang yao
a chen » ta chen, _ chen, n chen

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: yang yang ka ((a chen) OR (((yulu cheng) OR (yulu chen)))) chan ming ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang ka ((a chen) or (((yulu cheng) or (yulu chen)))) chan ming ((wong sau) OR (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang ka ((a chen) or (((yulu cheng) or (yulu chen)))) chan ming ((wong sau) OR (wong sam)) ;*.
