Original poem:
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.

Poetry appreciation
This poem is a metaphor for things as well as books. It shows that only by constantly learning and updating knowledge can we maintain vigorous vitality and have a higher education. The beauty of this poem lies in its inseparable from "reading" and "Guantang". Writing Tang Fang is like a book. "Sword" is like the level of a pond, which also means the fluency of books.
Because of this, I jumped into writing "sky and cloud", which has nothing to do with "book", and cut "sword" and "water" closely, thus leading to "flowing water at the source", which is natural and convenient. But on second thought, readers' thoughts are all included in this topic for reasons of reading and writing books. Because of the author's careful observation and firm expression, it is interesting to read.
Similarly, the "source of living water" includes not only book knowledge but also life practice. This is also the effect of the author's metaphorical reasoning, leaving room for imagination to supplement it.
