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

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