Perhaps you should try some spelling variations:
sein dann » sein kann, sein das, bin dann
chen rong » chen yang
ein dank » mein dank, bin dann, ein dach
wang yue » wong yue, wang hua, wang yan
yi chen » jui chen
rong di » dong di, gong di, long did
yang xi » yang di, yang yi, yang jui

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: dong ((sein dann) OR (ein dank)) yi chen rong di ((wang yue) OR (yang xi)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong ((sein dann) or (ein dank)) yi chen rong di ((wang yue) or (yang xi)) ;*.
