Perhaps you should try some spelling variations:
cheng ming » cheng bing, chen ping, zhang ming
cheng ling » cheng bing, cheng leong, chen ping
sang yue » wang yue, yang yue, sang hyup
jin wong » jin song, john wong, jin ying
wong sau » wong sam, wong siu, wong shiu
sang yu » sang hyup, wang yue, mang yul
wang » wing, lang

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: (wang OR wan) yan ((sang yu) OR (sang yue)) ((cheng ming) OR (cheng ling)) jin wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan ((sang yu) or (sang yue)) ((cheng ming) OR (cheng ling)) jin wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan ((sang yu) or (sang yue)) ((cheng ming) OR (cheng ling)) jin wong sau ;*.
