Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
heat gain » health gain, health gains, wheat grains
shang hai » shang kai, dang hai, chang ha
wenn man » kann man, wenn das
ann heat » a heat
yan wang » yuan wang, yang yang, qian wang
yang jie » yang jin, yang di, yang jui
man ann » man kann

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 wang) OR (yang liang))) OR (yang jie)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wenn man ann heat gain ((((yan wang) or (yang liang))) or (yang jie)) shang hai ;*.
