Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
heat gain » health gain, health gains, wheat grains
yang jie » yang jin, yang jui, yang xi
hong hai » shang hai, zhong tai, dang hai
man han » man hat, man kann, man what
man can » woman can, man kann
kann » ann

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: kann ((man han) OR (man can)) heat gain ((yang liang) OR (((yang jie) OR (yang di)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "kann ((man han) OR (man can)) heat gain ((yang liang) or (((yang jie) or (yang di)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: kann ((man han) OR (man can)) heat gain ((yang liang) or (((yang jie) or (yang di)))) hong hai ;*.
