Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
sharing risk » sharing best, during risk
risk hong » risk among, risk along, risk how
hua rent » hua ren
hong shu » cong shu, tong shui, wong shiu
yang yi » yang xi, yang jui
yang y » yang _, yang 8, yang 4

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: wang ((yang di) OR (((yang y) OR (yang yi)))) hua rent sharing risk hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang di) or (((yang y) OR (yang yi)))) hua rent sharing risk hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang di) or (((yang y) OR (yang yi)))) hua rent sharing risk hong shu ;*.
