What does "reading a book" mean?

Meaning: A pond half an acre square is displayed like a mirror, in which the brilliance of the sky and the shadow of floating clouds move together. Why is the water in that square pond so clear? It is because there is an inexhaustible source to continuously transport living water for it.

Original text:

Half an acre of square pond opened, and the sky was overcast.

Why is the water in the pond so clear? Because there is inexhaustible living water for it.

Two thoughts on reading is a set of poems by Zhu, a Neo-Confucianism scholar in Song Dynasty.

Appreciation of works:

The poet uses scenery as a metaphor, vividly and profoundly, and skillfully expresses a subtle and pleasant reading feeling. The aura, clarity, cheerfulness, liveliness and complacency of this poem are exactly the author's personal reading experience as a scholar.

Although the feelings expressed by the poet in his works are only about reading, they are profound in meaning and rich in connotation, which can be widely understood. In particular, the phrase "ask how to clear the canal so that it can follow the flowing water from the source" seems to be because of the continuous injection of flowing water from the source, so the water is "so clear". In fact, it indicates that if people want to be clear-headed, they must constantly study hard, constantly seek novelty and novelty, and constantly acquire new knowledge, so as to reach the highest level.
