Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
kong sara » kong sar
yang hua » wang hua, yang hui, ying hua
jin kong » jin kang, jin song, king kong
wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang yi, yang jui

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