Perhaps you should try some spelling variations:
bean grain » soybean grain
yang liang » wang liang, yan liang, yang yang
zhong tai » hong tan, hong hai, zhong zhi
can bean » can beat, can break, can best
yang jie » yang jin, yang jui, yang xi
man can » man han, woman can, man kann
kann » ann

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: kann man can bean grain ((yang liang) OR (((yang jie) OR (yang di)))) zhong tai ;~.
• Adding a wildcard symbol may retrieve word variants: kann man can bean grain ((yang liang) or (((yang jie) or (yang di)))) zhong tai ;*.
