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

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