Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
wang ling » wang liang, wang jing, wang ning
hong shu » cong shu, tong shui, wong shiu
yang 2 » yang _, yang d, yang y
yang 4 » yang 47, yang _, yang d
yang 8 » yang _

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ling ((((yang 2) OR (yang 4))) or (yang 8)) cost sharing tan hong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ling ((((yang 2) OR (yang 4))) OR (yang 8)) cost sharing tan hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ling ((((yang 2) OR (yang 4))) or (yang 8)) cost sharing tan hong shu ;*".
