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
shang hai » shang kai, dang hai, chang ha
yang jin » yang jie, yang jun, ying jin
man han » man hat, man kann, man what
man can » woman can, man kann

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