Perhaps you should try some spelling variations:
crises china » crisis china's, classes china, crises asia
crises cong » crises costs, crises cross
exit during » credit during, mexico during
liang yang » wang yang, yang yang, huang yang
liang ying » liang liying, huang ying, zhang ying
den exit » eu exit, new exit

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: wang ((liang yang) OR (liang ying)) den exit during ((crises cong) OR (crises china)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) or (liang ying)) den exit during ((crises cong) OR (crises china)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) or (liang ying)) den exit during ((crises cong) OR (crises china)) shu ;*.
