Each counterclockwise loop actually earns you one silver.

每个逆时针循环实际上为您赢得一枚银牌。

You start off owing four silver, so four counterclockwise loops would get you down to zero.

你开始欠四银，所以逆时针循环四次会让你降到零。

But there’s another way to reduce your bill: walking one large counterclockwise loop through the city.

但还有另一种减少费用的方法：逆时针走一个大环路穿过城市。
