Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
heat gain » health gain, health gains, wheat grains
hua gain » run gain, hua ban, via gain
yang jie » yang jin, yang jui, yang xi
hong hai » shang hai, zhong tai, dang hai
wan man » woran man, kann man, wenn man
man tan » man can, man han, man tun

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 tan ((hua gain) OR (heat gain)) ((yan liang) OR (((yang jie) OR (yang di)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan man tan ((hua gain) OR (heat gain)) ((yan liang) or (((yang jie) or (yang di)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan man tan ((hua gain) OR (heat gain)) ((yan liang) or (((yang jie) or (yang di)))) hong hai ;*.
