Perhaps you should try some spelling variations:
what grains » wheat grains, what brain, what remains
wang liang » wang yang
yang liang » yan liang, yang yang, peng liang
kann what » man what
dang hari » dang hai
wenn man » kann man, wenn das
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 man kann what grains ((((wang liang) OR (yang liang))) OR (ying jin)) dang hari ;~.
• Adding a wildcard symbol may retrieve word variants: wenn man kann what grains ((((wang liang) or (yang liang))) or (ying jin)) dang hari ;*.
