The Wild Bora and the Fox

A wild boar stood under a tree and rubbed his tusks against the trunk.A fox passing by asked him why he thus sharpened his teeth when there was no danger threatening from either huntsman or hound.He replied,"I do it advisedly;for it would never do to have to sharpen my weapons just at the time I ought to be using them."

It is too late to whet the sword when the trumpet sounds to draw it.

野猪与狐狸

一只野猪站在大树下，将它的长牙齿在树干上磨得更加锋利。这时一只狐狸正好路过看见了，狐狸就问野猪说：现在没有猎人追赶，又没有猎狗围攻，危险根本就不存在，干嘛要这样做呢？野猪回答说：“我这样做是有道理的，因为一旦我需要使用牙齿的时候，我就不会有时间再把它磨锋利了。”

临阵磨枪是兵家的大忌。
