The idiom story of "a levee of a thousand miles, collapsed in an ant's nest"
There is a village on the bank of the Yellow River. In order to prevent the Yellow River from flooding, farmers built towering long dikes. One day, an old farmer happened to find that the nest suddenly increased a lot. The old farmer doubted whether these nests would affect the safety of Long Beach. He was about to report back to the village when he met his son on the way.
The old farmer's son said disapprovingly, are you still afraid of a few small ants on a strong long embankment? Pull the old farmer to the fields together. It was stormy that night, and the water of the Yellow River soared. The roaring river oozed from the ant nest, then sprayed and finally flooded the dam.
