Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
risk ying » risk laying, risk using, risk young
hua cost » a cost, eu cost, run cost
can cost » can costa, can lost, can post
ying shu » ying zhu, cong shu, ying hua
up cost » up costs
yan yi » yang yi, tan yi, yan zi
tan li » tang li, tian li, gan li

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 ((yan yi) OR (tan li)) ((((hua cost) OR (can cost))) OR (up cost)) sharing risk ying shu ;~.
• Adding a wildcard symbol may retrieve word variants: wing ((yan yi) or (tan li)) ((((hua cost) or (can cost))) or (up cost)) sharing risk ying shu ;*.
