Perhaps you should try some spelling variations:
earnings loss » earnings losses, learning loss
lost earnings » low earnings, gross earnings, cash earnings
loss among » costs among, jobs among
yang yang » wang yan
wang yang » wang yan, wang yanling
among ers » among peers, among users, among east

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((yang yang) OR (wang yang)) lost earnings loss among ers ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ((yang yang) OR (wang yang)) lost earnings loss among ers ;*.
