Perhaps you should try some spelling variations:
cash earnings » bank earnings, age earnings
lost earnings » low earnings, gross earnings, flow earnings
wang liang » wang yang
risk wrong » risk among, risk along
wrong who » wrong why, wrong what, wrong when
yang can » yang fan, yang dean, yang yang

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) OR (wang yan)) yang can ((lost earnings) OR (cash earnings)) risk wrong who ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yan)) yang can ((lost earnings) OR (cash earnings)) risk wrong who ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yan)) yang can ((lost earnings) OR (cash earnings)) risk wrong who ;*.
