Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
han chang » huang chang, than change, can change
yang muxi » yang xi, yang hui, yang mu
hold kong » hold young, hong kong
yang jui » yang judy, 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: han chang ((yang muxi) OR (yang jui)) ((rent sharing) OR (cost sharing)) hold kong (sar OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "han chang ((yang muxi) or (yang jui)) ((rent sharing) OR (cost sharing)) hold kong (sar or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: han chang ((yang muxi) or (yang jui)) ((rent sharing) OR (cost sharing)) hold kong (sar or saur) ;*.
