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

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