Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
heat gain » health gain, health gains, wheat grains
yan liang » wang liang, you liang, yan wang
wenn man » kann man, wenn das
ann heat » a heat
ying jin » yang jin, jing ji, yang jie
man ann » man kann
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 ann heat gain ((((yan liang) OR (yang liang))) OR (ying jin)) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wenn man ann heat gain ((((yan liang) or (yang liang))) or (ying jin)) dang hai ;*.
