Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
heat gain » health gain, health gains, wheat grains
zhong tai » hong tan, hong hai, zhong zhi
yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie
man han » man hat, man can, man what
kann » ann

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wenn ((man han) OR (man kann)) heat gain ((yan liang) or (((yang jin) or (ying jin)))) zhong tai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wenn ((man han) OR (man kann)) heat gain ((yan liang) OR (((yang jin) OR (ying jin)))) zhong tai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn ((man han) OR (man kann)) heat gain ((yan liang) or (((yang jin) or (ying jin)))) zhong tai ;".
• Adding a wildcard symbol may retrieve word variants: wenn ((man han) OR (man kann)) heat gain ((yan liang) or (((yang jin) or (ying jin)))) zhong tai ;*.
