Perhaps you should try some spelling variations:
china chan » china chang, china can, china chen
chan ming » kian ming, chan eng, chan fong
ming cong » minh cong, ming kong, ming code
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
ho china » mao china, lao china, ho chi
cong sun » cong shu, cong van, wing sun
yang yi » yang di, yang xi

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: (wing OR lang) ((((yang jie) OR (yang jui))) OR (yang yi)) ho china chan ming cong sun ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((((yang jie) or (yang jui))) or (yang yi)) ho china chan ming cong sun ;*.
