Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
ren shang » wei shang
dong nan » dong yang, dong sin, dong cao
dong bin » dong sin, dann bin
jin ying » li ying
ying shu » ying zhu, cong shu, ying hua
dong di » dong sin

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong nan) or (((dong bin) or (dong di)))) ya hua ((ren shang) OR (rent sharing)) jin ying shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (((dong bin) OR (dong di)))) ya hua ((ren shang) OR (rent sharing)) jin ying shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((dong bin) or (dong di)))) ya hua ((ren shang) OR (rent sharing)) jin ying shu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (((dong bin) or (dong di)))) ya hua ((ren shang) OR (rent sharing)) jin ying shu ;*.
