Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking, cost sharing
wang yang » wang liang, wang yanling
sharing a » sharing _
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
di rent » des rent, der rent, oil rent
hong yu » wong yue

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 ((wang yang) OR (wang yan)) di rent sharing a ((((wong sau) OR (wong siu))) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((wang yang) or (wang yan)) di rent sharing a ((((wong sau) OR (wong siu))) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((wang yang) or (wang yan)) di rent sharing a ((((wong sau) OR (wong siu))) or (hong yu)) ;*.
