Perhaps you should try some spelling variations:
rates around » wages around, battles around, rating around
rail costs » real costs, travel costs
zhang yan » zhang fan, zhang jian, wang yan
yan among » yan cong
rail cost » real cost, oil cost, travail cost
rate band » rate bonds
arms » farms, aims, arts

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: zhang yan among ((rail cost) OR (rail costs)) savings ((rates around) OR (rate band)) arms ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan among ((rail cost) OR (rail costs)) savings ((rates around) or (rate band)) arms ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan among ((rail cost) OR (rail costs)) savings ((rates around) or (rate band)) arms ;*.
