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
wenn man » kann man, wenn das
yang jin » yang jie, yang jun, ying jin
hai » hadi, haji, hari

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