Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
yan yang » yang yang, yao yang, dan yang
hong shu » cong shu, tong shui, wong shiu
wong yue » wang yue, hong yu
wan yan » wang yan, nan yan, wai yan
yang yi » yang di, yang xi, 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 yi ((rent sharing) OR (cost sharing)) tan ((hong shu) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang yi ((rent sharing) OR (cost sharing)) tan ((hong shu) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yang yi ((rent sharing) OR (cost sharing)) tan ((hong shu) or (wong yue)) ;*.
