Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
ying zhou » ying zhu, fang zhou, gang zhou
kong sara » kong sar
yang hui » yang jui, wang hui, yang muxi
jin kong » jin kang, jin song, king kong
wang » wing, wan, lang

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 yan ((ying zhou) OR (yang hui)) ((rent sharing) OR (cost sharing)) jin kong sara ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((ying zhou) or (yang hui)) ((rent sharing) OR (cost sharing)) jin kong sara ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((ying zhou) or (yang hui)) ((rent sharing) OR (cost sharing)) jin kong sara ;*.
