Perhaps you should try some spelling variations:
sharing a » sharing _
jiang yi » jiang ye, jia yi, ming yi
can cost » can costa, can lost, can post
yang shu » cong shu, tan shu, yang hui
yang yi » yang di, yang xi, yang jui
up cost » up costs
yang du » yang di, yang d, yang mu

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: wang ((jiang yi) OR (yang yi)) ((up cost) OR (can cost)) sharing a ((yang shu) OR (yang du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((jiang yi) OR (yang yi)) ((up cost) or (can cost)) sharing a ((yang shu) or (yang du)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((jiang yi) OR (yang yi)) ((up cost) or (can cost)) sharing a ((yang shu) or (yang du)) ;*.
