Perhaps you should try some spelling variations:
what grains » wheat grains, what brain, what remains
kann what » man what
yan liang » yang liang, wang liang, you liang
dang hari » dang hai
wenn das » wenn die
das kann » das kind, man kann, das kino
ying jin » yang jin, jing ji, yang jie

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: wenn das kann what grains ((yan liang) OR (ying jin)) dang hari ;~.
• Adding a wildcard symbol may retrieve word variants: wenn das kann what grains ((yan liang) or (ying jin)) dang hari ;*.
