Perhaps you should try some spelling variations:
where guo » where do, where sun, where obo
sin kann » sein kann, wie kann, man kann
10 where » 1 where, 1.2 where, 2 where
guo feng » gu feng, guo jing, guo ming
yang jui » yang xi
kann 10 » kant 10
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 10 where guo feng ((yang judy) OR (((((yang yi) OR (yang jui))) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin kann 10 where guo feng ((yang judy) or (((((yang yi) or (yang jui))) or (yang di)))) ;*.
