Perhaps you should try some spelling variations:
heat gain » health gain, health gains, wheat grains
dang hari » dang hai
run gain » run pain
yang jui » yang judy, yang di
yan han » man han, yan zhang, kang han
yang xi » yang di
yang yi » yang di
wang » wing, wan, lang

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: wang yan han ((heat gain) OR (run gain)) ((((yang xi) OR (yang yi))) OR (yang jui)) dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan han ((heat gain) or (run gain)) ((((yang xi) OR (yang yi))) or (yang jui)) dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan han ((heat gain) or (run gain)) ((((yang xi) OR (yang yi))) or (yang jui)) dang hari ;*.
