Perhaps you should try some spelling variations:
health gains » health gain, health gaps, health goals
bad health » based health, card health, das health
wang liang » wang yang
shang hai » dang hai, chang ha, hong hai
ying jin » yang jin, jing ji, yang jie
man bad » man made, than bad
kann » ann

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: kann man bad health gains ((wang liang) OR (ying jin)) ((shang hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "kann man bad health gains ((wang liang) or (ying jin)) ((shang hai) OR (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: kann man bad health gains ((wang liang) or (ying jin)) ((shang hai) OR (shang kai)) ;*.
