Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
tong shui » tong hui, cong shu, gong hui
yan yang » yang yang, yao yang, dan yang
yang jui » yang judy, yang di, yang xi
wan yan » wang yan, nan yan, wai yan
hong yu » wong yue

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 jui ((rent sharing) OR (cost sharing)) tan ((tong shui) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang jui ((rent sharing) OR (cost sharing)) tan ((tong shui) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yang jui ((rent sharing) OR (cost sharing)) tan ((tong shui) or (hong yu)) ;*.
