Perhaps you should try some spelling variations:
chen aizheng » chen zheng, chen zhen, chen jiageng
yang yang » wang yang, wang yan
wong sau » wong shiu, wong lai, kong sar
wong sam » wong lai, kong sar, von sam
wong siu » wong shiu, kong siu, wong siew
yang xi » yang di, yang yi, yang jui
xi chen » xi cheng, yi chen, li chen
wang » wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wing) yang yang xi chen aizheng min ((((wong sau) OR (wong sam))) or (wong siu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yang yang xi chen aizheng min ((((wong sau) OR (wong sam))) OR (wong siu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yang yang xi chen aizheng min ((((wong sau) OR (wong sam))) or (wong siu)) ;*".
