Perhaps you should try some spelling variations:
cheng ming » cheng bing, cheng ling, chen ping
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
chen ming » chen ping, chen jing, chen liming
chan ming » kian ming, chan eng, chan fong
wong siu » wong shiu, kong siu, wong sau
di li » li li

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang yang di li ((((chen ming) OR (chan ming))) or (cheng ming)) ((wong siu) or (cong shu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang di li ((((chen ming) OR (chan ming))) OR (cheng ming)) ((wong siu) OR (cong shu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang di li ((((chen ming) OR (chan ming))) or (cheng ming)) ((wong siu) or (cong shu)) ;*".
