Perhaps you should try some spelling variations:
sharing mining » sharing during, sharing learning
rent sharing » risk sharing, rent seeking, cost sharing
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
jin rent » oil rent
hong g » hong ng, hong w, hong 7
wang » wing, wan

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 OR lang) ((yan liang) OR (yang liang)) jin rent sharing mining ((hong g) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yan liang) OR (yang liang)) jin rent sharing mining ((hong g) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yan liang) OR (yang liang)) jin rent sharing mining ((hong g) or (hong seo)) ;*.
