A blind man is good at touching all the things.

No matter whatever the thing is he can distinguish it as soon as he touches it

A man brings a young wolf and lets him touch it.

Having touched the animal, he says, "This is a fox or a wolf, I am not sure. But I know that putting this kind of animal into the sheep pen is not safe"

The story means: we can know someone's bad habits from when he is young.

一个瞎子精于用手触摸各种动物。

什么动物只要他一摸，就能分辨出来。

有人带来一只小狼，请他摸一摸，说出是什么东西。

他摸了摸这个小野兽后说：“这是一只狐狸或者一匹狼，啊，我不太清楚。不过有一点我却十分地明白，让这种动物进羊栏是不安全的。”

这个故事是说一个人的恶习在年幼时便可得知。
