wang liang » wang yang
wenn das » wenn die
yang jun » yang jui, pang jun, yang jin
chang ha » chang mae
das hat » das habt, das hal, das haus

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

• Performing a fuzzy search may retrieve terms with similar spellings: wenn das hat ((health gaps) OR (health gains)) ((wang liang) or (yang jun)) chang ha ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wenn das hat ((health gaps) OR (health gains)) ((wang liang) OR (yang jun)) chang ha ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn das hat ((health gaps) OR (health gains)) ((wang liang) or (yang jun)) chang ha ;*".
