Perhaps you should try some spelling variations:
states during » rates during, states making, strategies during
states using » rates using, estimates using, studies using
wang yang » wang yan, wang liang, wang yanling
yang jie » yang jin, yang di, yang jui
yu yang » du yang, yi yang, yu fang
jie art » die art, fine art, eine art

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) or (yu yang)) yang jie art ((states using) OR (states during)) dhm bei ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yu yang)) yang jie art ((states using) OR (states during)) dhm bei ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yu yang)) yang jie art ((states using) OR (states during)) dhm bei ;*".
