"To practice" has two meanings:
First, in the process of learning, we should "practice" and strive to achieve "mouth to mouth, hands to heart";
The second is to "practice" after acquiring knowledge, and turn it into your own and your own use through personal practice. The poet's intention is very obvious, aiming at encouraging his son not to be unilaterally satisfied with book knowledge, but to consolidate and further sublimate in practice.
Original text:
Reading in winter night, Xianzi said
Song dynasty:? Lu you
The ancients learned nothing, and it takes time to grow old.
What you get on paper is so shallow that you never know what you have to do.
The ancients spared no effort in learning, worked hard when they were young, and achieved nothing when they were old. After all, the knowledge gained from books is not perfect. If you want to know things thoroughly, you must practice it yourself.

Full text appreciation:
This is a godson poem, and the poet emphasizes the importance of practice in the relationship between books and practice. Indirect experience is a way for people to draw nutrition from books and learn the knowledge and skills of their predecessors.
Direct experience is an understanding that comes directly from practice, and it is a more important way to acquire knowledge. Only by "practice" can we turn book knowledge into practical knowledge and play the guiding role of what we have learned in practice. By describing Lu You's education to his son Yu Zi, this poem tells readers to have a tireless and persistent learning spirit. A person who has both book knowledge and practical spirit is a truly learned person.
