Perhaps you should try some spelling variations:
heat gain » health gain, health gains, wheat grains
hua gain » run gain, hua ban, via gain
yang jie » yang jin, yang di, yang jui
pang jun » yang jui
wan man » woran man, kann man, wenn man
man can » man han, woman can, man kann
yang li » yang lin, yang di, yang xi
hai » hadi, haji, hari

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: wan man can ((hua gain) OR (heat gain)) ((yang li) OR (((yang jie) OR (pang jun)))) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan man can ((hua gain) OR (heat gain)) ((yang li) or (((yang jie) or (pang jun)))) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan man can ((hua gain) OR (heat gain)) ((yang li) or (((yang jie) or (pang jun)))) dang hai ;*.
