Perhaps you should try some spelling variations:
hear gain » heat gain
yan liang » yang liang, wang liang, you liang
zhong tai » hong tan, hong hai, zhong zhi
can hear » can gear, can learn, can help
yang jin » yang jie, yang jun, ying jin
man can » man han, woman can, man kann
yang yi » yang di, yang xi, yang jui
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 can hear gain ((yan liang) OR (((yang jin) OR (yang yi)))) zhong tai ;~.
• Adding a wildcard symbol may retrieve word variants: kann man can hear gain ((yan liang) or (((yang jin) or (yang yi)))) zhong tai ;*.
