Perhaps you should try some spelling variations:
iran cost » urban cost, iran case, can cost
sharing a » sharing _
run cost » can cost, run cash, run out
ying shu » ying zhu, cong shu, ying hua
yan yi » yang yi, tan yi, yin yi
yan zi » yan zhi, yuan zi, ban zi
a ying » ka ying, _ ying, fan ying

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

• Performing a fuzzy search may retrieve terms with similar spellings: wing ((yan yi) OR (yan zi)) ((((run cost) or (up costs))) or (iran cost)) sharing a ying shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yan yi) OR (yan zi)) ((((run cost) OR (up costs))) OR (iran cost)) sharing a ying shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan yi) OR (yan zi)) ((((run cost) or (up costs))) or (iran cost)) sharing a ying shu ;".
• Adding a wildcard symbol may retrieve word variants: wing ((yan yi) OR (yan zi)) ((((run cost) or (up costs))) or (iran cost)) sharing a ying shu ;*.
