Perhaps you should try some spelling variations:
chen yong » chen rong, zhen yong, chen wang
chen ping » chen rong, chen wang
chen yang » chen rong
wang ban » wang yan, wang dan, wang yang
jin song » jie song, john song, kim song
ban yan » nan yan, wang yan, qian yan
yan ji » yan jiu, ban ji, pan ji

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 ban yan ji ((((chen yong) OR (chen ping))) OR (chen yang)) jin song (shin OR thin) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ban yan ji ((((chen yong) or (chen ping))) or (chen yang)) jin song (shin or thin) ;*.
