Perhaps you should try some spelling variations:
states during » rates during, states making, strategies during
states using » rates using, estimates using, studies using
ying yang » yang yang, yin yang, ying chang
jie small » live small, wine small, one small
yang jie » yang jin, yang di, yang jui
yu yang » du yang, yi yang, yu fang

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: ((ying yang) OR (yu yang)) yang jie small ((states using) OR (states during)) dem bei ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ying yang) or (yu yang)) yang jie small ((states using) OR (states during)) dem bei ;~".
• Adding a wildcard symbol may retrieve word variants: ((ying yang) or (yu yang)) yang jie small ((states using) OR (states during)) dem bei ;*.
