Perhaps you should try some spelling variations:
cheng ming » cheng bing, cheng ling, chen ping
cheng ying » cheng bing, cheng ling, chen yang
yang yie » yang jie, yang yue, yang di
jin song » jie song, john song, kim song
song sau » wong sau, kong sar, song pae
yang yi » yang di, yang xi, yang jui
wang » wing, wan, 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 yan ((yang yi) OR (yang yie)) ((cheng ying) OR (cheng ming)) jin song sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang yi) or (yang yie)) ((cheng ying) OR (cheng ming)) jin song sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang yi) or (yang yie)) ((cheng ying) OR (cheng ming)) jin song sau ;*.
