This article begins with a metaphor, "What do you think of the rich?" A question not only naturally leads to the following, but also attracts special attention. Then it tells the story of two different effects brought by rich and poor farming methods vividly and concretely. The stronger the fertility of the rich, the richer the harvest; The fertility of the poor is getting worse and worse, and the harvest is meager.
The reason is that the rich have more land than food, so they can practice crop rotation, conserve soil fertility and form a virtuous circle, so they can continue to develop reproduction; If the poor can't do it, it will inevitably lead to a vicious circle, and finally even simple reproduction will be difficult to maintain. This is an irresistible production law! "In ancient times, only people were older than today."
The transformation of the article is logical, and the law of material production naturally extends to spiritual production. Comparing the ancients with the present, we think that the talents and knowledge of the ancients greatly exceeded those of ordinary people. The reason is the same as this kind of crops. Don't rush for success. You must accumulate time and practice diligently in order to achieve "overflowing, but starting from perfection".
Then, the author further expounds this problem with his own learning practice and personal experience. Don't be complacent in your study, pursue a false reputation, and concentrate on your study. Only by "reading widely and learning from others" can we have a rich and refined knowledge base, and we will be willing to use it. This is the truth of "thick accumulation and thin hair".
