What straw will crush a camel?

A master has an old camel. It works hard all day. Once, the owner wanted to see how much the old camel could hold, so he kept adding and adding, and the old camel didn't collapse. Finally, the owner doubted whether it had reached the limit, so he gently threw a straw on its back. Unexpectedly, it was this straw that made the old camel collapse.

This means that things have reached the threshold of the limit, and any additional factors will lead to its collapse. A straw, almost weightless. No one put straw in their eyes. But if you pile a straw on the camel's back, there will always be a straw over the camel.

Extended data:

This last grass played a role in igniting the fire, and it just exceeded the camel's load. So in order to emphasize the importance of this grass. It seems that things have changed because of this grass. In fact, there is a lot of grass ahead. That is, the principle that quantitative change causes qualitative change.

No matter how small the weight is, it can add up to a mountain. This is similar to "dripping water wears away the stone" and "the ant nest bursts its banks". The difference of this proverb is that it emphasizes: Never add the last straw.
