Perhaps you should try some spelling variations:
crisis comes » crisis becomes, crisis some, crisis cases
exit during » credit during, mexico during
crisis cong » crisis can, crisis could, crisis cross
liang yang » liang ying, yang yang, huang yang
wang yang » wang yan, wang liang, wang yanling
jean exit » jean petit, jean eric

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