Perhaps you should try some spelling variations:
sein dann » sein kann, sein das, bin dann
chen wong » chen rong, chen wang, chen yong
wong shiu » wong siu, cong shu, song shin
ein dank » mein dank, bin dann, ein dach
jui chen » yi chen
yang jui » yang judy, yang yi
yang xi » yang yi

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)) jui chen wong shiu ((((yang jui) OR (yang xi))) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: dong ((sein dann) or (ein dank)) jui chen wong shiu ((((yang jui) or (yang xi))) or (yang di)) ;*.
