Perhaps you should try some spelling variations:
peak heat » weak head
heat gain » health gain, health gains, wheat grains
yan peak » can speak, a peak
wang lin » wang li, wang qin, yang lin
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, wang jing
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: wang yan peak heat gain ((wang lin) OR (((yang jie) OR (((yang jin) OR (shang jin)))))) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan peak heat gain ((wang lin) or (((yang jie) or (((yang jin) OR (shang jin)))))) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan peak heat gain ((wang lin) or (((yang jie) or (((yang jin) OR (shang jin)))))) dang hai ;*.
