Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
wang liang » wang yang
sharing a » sharing _
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan kong, tan ying
hua cost » a cost, eu cost, run cost
song shu » cong shu, song shin, tong shui
a song » _ song, a strong

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: wing ((((tan yang) OR (tan yong))) OR (wang liang)) hua cost sharing a song shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((((tan yang) OR (tan yong))) or (wang liang)) hua cost sharing a song shu ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((((tan yang) OR (tan yong))) or (wang liang)) hua cost sharing a song shu ;*.
