What do the green trees on the south side of the street mean?

This is a masterpiece of travel. With exquisite brushwork, the whole poem starts from the immediate scene, gradually evokes memories and expresses nostalgia in revisiting the old place. Write a scene in the last movie. The first four sentences are the scenery and intention in the view of the north building facing south. It is because of the bird's eye view that you can see so far, you can see rows of willow trees, you can see the brilliant "charming clouds" woven by red and white tidbits, and you can see the sheep flying all over the sky. The "snowy spring road" here is the whimsy of willow "loosening" and points out the word "late spring" at the same time. As for the "Zhu Hu at the bottom of the tree", it is faintly visible from the gap of the "tree head". It is hidden in beautiful clouds, which vividly shows an urgent search situation. Through the film from the scene to the emotion, I wrote the modality and psychology that people could not bear to leave in the text. "Late spring" is the reason why I am reluctant to leave. Obviously, it's not today, and "late spring" is not now, but the place where "shade" and "moss" are located must be "people" under "green trees in the south of the street" Most importantly, this is the place where people used to travel in the world. Touching the scene like this, there must be special events worthy of permanent commemoration. Therefore, the knot is "the fallen flowers are still there, the fragrance screen is empty, and people know where to go!" Point out the meaning of the word. I feel the pain of falling flowers more than the sentence "Peach blossoms still laugh at the east wind". The people in the poem only look around the north building. It turned out that he visited the Iraqi who had never appeared. There is no news from her, but "the screen is empty." This word is in line with the artistic conception of Cui Hu's poem "South Village of Capital" in the Tang Dynasty-"Today last year, peach blossoms set each other off in this door. People don't know where to go, but the peach blossom still smiles at the east wind, which has the same effect. Readers will feel the difference in artistic expression between the two works. "I hope what I borrowed from other places will help you.
