Perhaps you should try some spelling variations:
heat gain » health gain, health gains, wheat grains
yan liang » yang liang, wang liang, you liang
dang hadi » dang hai
can heat » can beat, can hear, ocean heat
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang xi
man can » man han, woman can, man kann
woran » woman, moran, goran

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: woran man can heat gain ((yan liang) OR (((yang jun) OR (yang jui)))) dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: woran man can heat gain ((yan liang) or (((yang jun) or (yang jui)))) dang hadi ;*.
