It means a small ant nest, which can make the bank burst, and a hole the size of a needle can also let the air escape. This sentence reminds people that as soon as disasters sprout, people should start to deal with them and prevent them before they happen; If you don't pay attention to small things, you may lose all your efforts and subvert all the accumulated "achievements" in an instant.
What we usually pay attention to is that "the nine-story platform starts from tired soil; "A journey of a thousand miles begins with a single step", achievements in career and moral character are the accumulation of long-term quantitative changes, which often go through a difficult process.
What should attract more attention is that the "dam" of personality cultivation has been built, and the "water" inside is also abundant, and the cause is as big as a "balloon", colorful, dazzling and eye-catching. But why do you sometimes "turn over" overnight?
Due to sudden and irresistible external factors, "dam break" and "rolling" sometimes occur in nature, but it seems impossible for human beings themselves. "No one is perfect" has happened, and some minor faults and mistakes that have nothing to do with "big festivals" are occasionally committed once or twice, which may not lead to ultimate failure.
However, if we don't pay attention to these "small things", we don't think so. Some people even label them as "positive" personal charm and characteristics, thinking that they are too big, so their pride is getting stronger and stronger, and small things become big festivals, small things become big events, and eventually they will get out of hand.
In this case, it can also be inferred that such people's inner psychological pursuit of "fame" and "political achievements" is inherently problematic, not for the long-term and ultimate interests of the people, but mostly for self-interest. As the thinker Wang Yangming pointed out in History, "an armchair strategist", of course, its "soap bubble" is easy to puncture and short-lived.
