Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
yang hua » wang hua, yang jui, wang hui
ying hua » ming hua, wang hua, ying zhu
yang hui » yang jui, wang hui, yang muxi
jin song » john song, kim song, jin ying
jie song » jae song, kim song, li song
wan yan » wang yan, nan yan, wai yan

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 hua) OR (ying hua))) OR (yang hui)) rent sharing ((jin song) OR (jie song)) sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((yang hua) or (ying hua))) or (yang hui)) rent sharing ((jin song) OR (jie song)) sau ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((((yang hua) or (ying hua))) or (yang hui)) rent sharing ((jin song) OR (jie song)) sau ;*.
