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