Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
rent sharing » risk sharing, rent seeking, cost sharing
yuan chang » yuan cheng, huang chang, han chang
risk kong » risk among, risk along, risk bond
yang jui » yang judy, yang di, yang xi
yang yi » yang di, yang xi

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: yuan chang ((wang hua) OR (((yang yi) OR (yang jui)))) rent sharing risk kong (sar OR star) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan chang ((wang hua) or (((yang yi) OR (yang jui)))) rent sharing risk kong (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan chang ((wang hua) or (((yang yi) OR (yang jui)))) rent sharing risk kong (sar or star) ;*.
