What does the last straw on the camel's back mean? Born?

It means the last straw that broke the camel's back. It is often used to describe that a thing has reached a critical point, and any slight quantitative change will cause qualitative change.

From an Arabic fable, it goes like this: A man has an obedient camel, and he wants to know how much straw that camel can carry. Then, he began to put straw on the camel. He put all the straw on it, leaving the last straw. The camel still stood there motionless. The master carelessly threw the last straw on the camel. As a result, the camel was crushed to death by this last straw

Extended data:

This fable tells the truth that quantitative change leads to qualitative change. It doesn't matter whether the straw pile collapses or not, and there is no need to discuss it. Well, first of all, let's not consider how much straw can be put on the camel's back. We assume that no matter how much straw is put, it will not collapse. Even so, it is not easy to crush a camel with straw.

The weight of a straw is almost zero, while a camel can carry at least 500 Jin. Without accurate calculation, we can imagine that the straw that can crush a camel must be astronomical. If we release them one by one, I'm afraid the camels are more likely to die of old age first.
