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 » iran cost, can cost, run cash
ying shu » ying zhu, cong shu, ying hua
wan yan » wang yan, nan yan, wai yan
up cost » up costs
yan yi » yang yi, tan yi, yan zi

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