Perhaps you should try some spelling variations:
heat gain » health gain, health gains, wheat grains
yan liang » yang liang, wang liang, you liang
shang hai » shang kai, dang hai, chang ha
wenn man » kann man, wenn das
hat heat » hat hat, a heat, hat hab
yang jui » yang judy, yang yi
yang xi » yang yi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wenn man hat heat gain ((yan liang) or (((((yang jui) OR (yang xi))) or (yang di)))) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wenn man hat heat gain ((yan liang) OR (((((yang jui) OR (yang xi))) OR (yang di)))) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn man hat heat gain ((yan liang) or (((((yang jui) OR (yang xi))) or (yang di)))) shang hai ;*".
