Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
rent sharing » risk sharing, rent seeking
minh chong » minh cong, min hong
dong yang » dong hoang, wang yang, yang yang
chong yun » chang yun, hong yu, chen yun
yang hua » wang hua, yang hui, yang jui
ying hua » ming hua, wang hua, ying zhu

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: dong yang ((yang hua) OR (ying hua)) ((rent sharing) OR (cost sharing)) minh chong yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ((yang hua) or (ying hua)) ((rent sharing) OR (cost sharing)) minh chong yun ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang ((yang hua) or (ying hua)) ((rent sharing) OR (cost sharing)) minh chong yun ;*.
