Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
than change » chain change, can change, mean change
sharing his » sharing risk, sharing big, sharing dps
han chang » huang chang, can change, chin chang
his kong » his son
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: ((han chang) OR (than change)) ((wang hua) OR (yang yi)) rent sharing his kong (sar OR star) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((han chang) OR (than change)) ((wang hua) or (yang yi)) rent sharing his kong (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: ((han chang) OR (than change)) ((wang hua) or (yang yi)) rent sharing his kong (sar or star) ;*.
