In the Eastern Han Dynasty, there was a young man named Chen Fan, who was pretentious and only wanted to do great things. One day, his friend Qin Xue visited and saw that the yard where he lived alone was dirty. He said to him, "Why don't you clean it for the guests?" He replied, "A gentleman wants to sweep the world and live in one room?" Qin Xue immediately asked, "If you don't sweep a house, how can you sweep the world?" Chen Fan was speechless.

Fan Chen's desire to "sweep the world" is certainly good, but what is wrong is that he doesn't realize that "sweeping the world" begins with "sweeping the house", including "sweeping the house", without which it is absolutely impossible to realize the ideal of "sweeping the world".

-Lao Tzu said: "Hemu is a lifetime; Nine-story platform, starting with tired soil; A journey of a thousand miles begins with a single step. "

-Xun Kuang's "Encourage Learning" said, "So if you don't accumulate steps, you can't go to Wan Li Road. If you don't accumulate small streams, you won't be a river. "

-Lenin, the revolutionary mentor of the former Soviet Union, also said, "If you want to achieve great things, you have to start from small things."

These wise sayings fully embody the philosophical relationship between "sweeping the world" and "sweeping a house", and explain that any major event is accumulated by small things. "Don't be small, but don't do it." No matter how small the "goodness" is, only by accumulating goodness can it become a virtue. Comrade Lei Feng's "sweeping the house" is the best example. He silently dedicated himself in his ordinary post, doing every little thing within his power.

On the surface, it means that if you don't clean a room, why should you calm the world?

In fact, it warns us that people who achieve great things need to start from small things, hold their heads high and do everything in life in a down-to-earth manner. If you do too many small things, you will achieve great things.
