Perhaps you should try some spelling variations:
cheng ying » cheng bing, cheng ling, cheng ming
dean cheng » jean chen, tan cheng, yuan cheng
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
ying jin » yang jin, jing ji, yang jie
kong siu » kong eiu, wong siu, dong sin
wong sau » wong sam, wong siu, wong shiu

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 ((yang yang) OR (wang yang)) dean cheng ying jin ((kong siu) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((yang yang) OR (wang yang)) dean cheng ying jin ((kong siu) or (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((yang yang) OR (wang yang)) dean cheng ying jin ((kong siu) or (wong sau)) ;*.
