Perhaps you should try some spelling variations:
health gains » health gain, health gaps, health goals
hal health » oral health, dual health, rail health
yan liang » yang liang, wang liang, you liang
shang hai » shang kai, dang hai, hong hai
wenn das » wenn die
yang jun » yang jui, pang jun, yang jin
chang ha » chang mae
das hal » das habt, das haus

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: wenn das hal health gains ((yan liang) OR (yang jun)) ((shang hai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn das hal health gains ((yan liang) or (yang jun)) ((shang hai) OR (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wenn das hal health gains ((yan liang) or (yang jun)) ((shang hai) OR (chang ha)) ;*.
