Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
heat gain » health gain, health gains, wheat grains
wang yang » wang yan, wang liang, wang yanling
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
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 (wang yang))) or (yang jin)) hong 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 (wang yang))) OR (yang jin)) hong 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 (wang yang))) or (yang jin)) hong hai ;*".
