Appreciation

This poem describes the poet's meticulous feelings at the turn of summer and autumn. It seems that as soon as the beginning of autumn arrives, nature changes its appearance, and people's lives also undergo significant changes. The sense of season is very strong, the situation of the whole poem closely follows the title of the poem, and the conception is very clever. The whole spirit of this poem lies in the word "find". Write a hazy, melancholy and helpless mood.

The first sentence describes the changes in the scenery in the evening. At first, the little crows were still crows on the branches or on the eaves. When it gets dark, the crows return to their nests, and the crows can no longer be heard. Crows have the characteristic of nesting in groups, so in the evening, crows crow more frequently. Old crows don't like to crow very much, and their crows are rough and unpleasant to hear. The Milk Crow prefers to call, and its voice is softer. It's not that hard to listen to.

In the evening, the calligraphy and painting on the jade screen can still be seen more clearly. When it gets dark, the calligraphy and painting on the jade screen are invisible and appear empty. Of course, the crows could not be heard and the calligraphy and paintings on the jade screen could not be seen, so the room seemed quiet and empty. The second sentence describes the poet's feelings when he was lying on the bed and fanning himself. Fanning in summer did not feel very cool because the temperature of the air was relatively high.

The fan blows at the beginning of autumn, and it feels particularly cool, because autumn has arrived and the air temperature is also lower. The word "Xin" in "Xinliang" expresses this change. Of course, there are also psychological factors at play in this qualitative change in feeling. Three sentences describe the process of the autumn wind blowing vigorously at night until it stops. At first I heard the autumn wind blowing the grass and trees making a whining sound, but after I got up I couldn't hear any sound at all.

Getting up to look for the sound of autumn shows that the poet is very concerned about the arrival of autumn. The last sentence was written in the bright moonlight. Seeing the steps covered with sycamore leaves, the poet finally clearly saw the footsteps of autumn. Because the air is crisp and clear in autumn, the autumn moon is particularly bright. Because the sycamore is a deciduous tree with wider leaves, it makes people think that the sycamore loses its leaves earlier and more conspicuously.
