Perhaps you should try some spelling variations:
daten rfm » daten im, daten ff
rfm where » from where
ii daten » die daten, 2 daten, 4 daten
where de » where do, where we, here de
yang jie » yang jin, yang jui, yang jun
dong ii » dong di, dong sin, dong bin
yang xi » yang jui
yang yi » yang jui
de ce » de cet

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 ii daten rfm where de ce ((((yang jie) OR (yang xi))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong ii daten rfm where de ce ((((yang jie) or (yang xi))) or (((yang di) or (yang yi)))) ;*.
