Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
sharing jin » shang jin, sharing big, sharing his
wing yan » wang yan, wing ian, wing tan
yang hua » wang hua, ying hua, yang jui
yang hui » yang jui, wang hui, yang muxi
song sau » kong sar, song pae, song so
wong sau » wong sam, wong siu, wong shiu

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

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