Advantages of the word "chaos" in "Mountain in Spring"

Hello, landlord. The advantage of scribbling is that the author writes two sentences from one sentence, which is natural and skillful. People's attention to things is often caused by hearing. The noise caused the poet to look up, so he wrote first that there were many crows in the sky at dusk, and it was conceivable that there were few people on the ground, which naturally led to the depression in the second sentence.
