As early as many years ago, I heard a saying that long dams will collapse because ants make holes in them. I was just young at that time, and I didn't understand it very well at the moment. Just last year, I had some feelings about this sentence.

Last Spring Festival, it was cold and windy. All the leaves of the tree have fallen off, and there are no birds on the branches, nor their ethereal songs. On New Year's Eve, I walked around my yard. When I came to the corner, I saw a stone step made of cement. I vaguely saw ants coming in and out on the stone steps. I bent down in doubt and found all the ants coming in and out of a small hole. They are neatly arranged in two columns, one in and one out, in good order. I stepped on the stone steps with my feet in some bad ways, and the seemingly solid stone steps collapsed and cracked. I didn't react at the moment and twisted my foot. "Why did such a solid stone step collapse?" I held back the pain and opened the gravel. There are many holes in the gravel, showing an irregular shape. It can be seen that it is the trace left by ants when they make holes. The seemingly solid stone steps left only a thin layer on the surface. I was a little surprised to see those ants. Small ants can actually destroy the internal structure of such a solid stone step. No wonder the stone steps are so fragile The phrase "A levee of a thousand miles collapses in an ant's nest" suddenly appeared in my mind.

My heart seems to be lit by fireworks at midnight on New Year's Eve, and I have a new understanding of the short eight words "A thousand miles of embankment collapsed in an ant nest". Tiny creatures like ants can destroy a long embankment thousands of miles away, so tiny leaks can sometimes cause fatal blows.

The same is true in learning. There are knowledge blind spots in learning, which may be small, but if we don't pay attention to them and solve them, we will only think a little and continue to let them go, which will lead to the collapse of the knowledge castle. If we think backwards, we can accumulate and make progress bit by bit, which can also decompose the biggest difficulty before us and lead us to the other side of success. Therefore, there is a saying that "don't use small goodness, don't use small evils". This kind of success or failure stems from the subtleties of "the levee of a thousand miles collapses in the ant nest". Isn't it a true portrayal?

"Details determine success or failure", work hard! Let's start with the smallest details, accumulate and succeed!
