Perhaps you should try some spelling variations:
chuan ming » chuan bang, yuan ming
wang wang » wang yang, wang liang, wang yan
chan ming » kian ming, chan eng, chan fong
wang gan » wang yan, wang ban, wang dan
code shu » code ctu
li chen » yi chen, jui chen
code c » code _, code 2, code a

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 wang gan li chen ((chuan ming) OR (chan ming)) ((code shu) OR (code c)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang gan li chen ((chuan ming) OR (chan ming)) ((code shu) or (code c)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang gan li chen ((chuan ming) OR (chan ming)) ((code shu) or (code c)) ;*.
