Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
sin dank » ein dank, mein dank, sein dann
when guo » shen guo, when good, when do
guo jing » guo ming, guo xin, cao jing
yang jui » yang judy, yang yi
yang xi » yang yi
dank i » dank 1
i when » ii when, 3 when, 4 when
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 dank i when guo jing ((((yang yang) OR (yang jui))) OR (((yang xi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin dank i when guo jing ((((yang yang) or (yang jui))) or (((yang xi) or (yang di)))) ;*.
