Perhaps you should try some spelling variations:
when learning » open learning, between learning
learning a » learning 1
kann even » kann ein, kann von
even when » level when, even what
sin kann » sein kann, wie kann, man kann
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang xi
yang yi » yang xi
dong » doing, long, done

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 sin kann even when learning a ((yang jin) OR (((((yang yi) OR (yang jui))) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin kann even when learning a ((yang jin) or (((((yang yi) or (yang jui))) or (yang di)))) ;*.
