Perhaps you should try some spelling variations:
when scaling » when dealing, when starting, when setting
level when » level where, level what, level we
sin kann » sein kann, wie kann, man kann
yang jun » yang jui, pang jun, yang jin
yang yi » yang jui
yang xi » yang jui
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 level when scaling up ((yang jun) OR (((((yang yi) OR (yang xi))) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin kann level when scaling up ((yang jun) or (((((yang yi) or (yang xi))) or (yang di)))) ;*.
