Note:

Lu You's Reading on a Winter Night.

the ancients had no power in learning, and it was only when they were young that they became old.

I've learned from the paper, but I don't know how to do it.

The ancients spared no effort in learning. When they were young, they studied hard until Laos achieved something. What you learn from books always feels shallow. If you really want to understand it, you have to practice it yourself.

This is the third of eight poems written to his youngest son to remind Lu You of his feelings about reading in winter nights. On the one hand, this poem emphasizes the importance of perseverance in learning, on the other hand, it emphasizes the importance of social practice. Because the knowledge learned from books, even if it is true and correct, has a barrier to oneself. Without personal practice, you can't understand the knowledge in books well. Therefore, in the process of learning, personal practice is extremely important.

I hope I can help you!
