Can someone help me appreciate the poem "Osmanthus fragrans" by Jiang Kui?

This is a poem that thinks of people by borrowing things. From the first sentence, we can see that "the empty mountain is looking for osmanthus trees, folding incense and thinking of old friends", and "empty mountain" refers to the empty valley, which also writes about the poet's inner emptiness, paving the way for writing that he is looking for osmanthus trees and thinking of old friends. Although the poet found osmanthus, he had no friends and could only be disappointed. The poet is looking for his friends all over the mountain. "An old friend and an old friend are separated by autumn waters, and always look back", this sentence describes the scene when he was separated from his old friend. Every step he took across the autumn water was so reluctant to go. At that time, the roads in the south and north of the mountain were full of flower trees, which were as bright as clouds when they opened, but it was in this beautiful scenery that the poet bid farewell to his friends and set off his sadness with music.

"Look at the oars when you are dry, and the agricultural branches will leave you." The poet leaned against the railing, looked at the boat in the distance, missed his friend, picked a few osmanthus flowers and looked forward to his friend's return. "Singing and dancing in the shadow of Xiling, the moonlight is angry", and the cool west wind blows away the singing and dancing, and the moonlight is so bright. The poet looked at the moon and thought of his friend alone in the moonlight. This sentence is the poet's deep feelings for his old friend in his daily life after he left. The next sentence is "Donate Yu Pei, and the fragrance will be autumn dust." In this case, it refers to the red Yu Pei, where all the flowers fall in autumn and become dirt. This sentence expresses the poet's feeling that good things are always so easy to disappear, and also expresses his sadness about the passing of good times in the past. Chu's singing sounds even sadder in this cool autumn, but the news about friends is never heard again, which adds to the poet's sadness and yearning. The poet can only stand alone in the cold wind and recite poems, letting the cool wind blow his clothes, but what he can't blow is the poet's endless yearning for his friends and the sadness caused by it. So this poem is about the poet expressing his deep thoughts for his friends by writing osmanthus flowers.
