Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
heat gain » health gain, health gains, wheat grains
yang yang » wang yang, wang yan
ying jin » yang jin, jing ji, yang jie
hong hai » shang hai, zhong tai, dang hai
das han » das haben, das handy, das human
das hal » das habt, das haus

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 ((das han) OR (das hal)) heat gain ((((yang liang) OR (yang yang))) OR (ying jin)) hong hai ;~.
• Adding a wildcard symbol may retrieve word variants: wenn ((das han) or (das hal)) heat gain ((((yang liang) or (yang yang))) or (ying jin)) hong hai ;*.
