Perhaps you should try some spelling variations:
where guo » where do, where sun, where obo
long sin » dong sin, long span, long run
sin kann » sein kann, wie kann, man kann
guo ming » guo jing, guo xin, guo feng
yang jun » yang jui, pang jun, yang jin
6 where » 2 where, 4 where, 1 where
yang xi » yang jui
yang yi » yang jui
kann 6 » kann 6.1

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: long sin kann 6 where guo ming ((yang jun) OR (((((yang xi) OR (yang yi))) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: long sin kann 6 where guo ming ((yang jun) or (((((yang xi) or (yang yi))) or (yang di)))) ;*.
