Perhaps you should try some spelling variations:
heat grains » wheat grains, heat gain, health trains
yan liang » yang liang, wang liang, you liang
shang hai » shang kai, dang hai, chang ha
wenn man » kann man, wenn das
ying jin » jing ji, yang jie
yang jin » yang jie, yang jun, shang jin
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: wenn man kann heat grains ((yan liang) OR (((ying jin) OR (yang jin)))) shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn man kann heat grains ((yan liang) or (((ying jin) OR (yang jin)))) shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wenn man kann heat grains ((yan liang) or (((ying jin) OR (yang jin)))) shang hai ;*.
