The so-called moon tears, see flowers sad. Du Fu's "Remission": "Worry about the frost and dew, cold city from chrysanthemum." I worry about the beauty, it's irrelevant. Song Ge Lifu quoted Zhao Zichang as saying in his rhyme in the Yangqiu period: "When people are comfortable, they will love the scenery, and if the beauty of things is set for me, the scenery has nothing to do with my indifference." Liu Yuxi of the Tang Dynasty in his Autumn Poems: "Since ancient times, when autumn is sad and lonely, I said that autumn is better than spring. When a crane rows clouds in the clear sky, it will lead poetry to the blue sky." This is a masterpiece of lamenting scenery and writing music. The first sentence describes the loneliness of our predecessors in autumn, and the second sentence describes our unique feeling that autumn is better than spring. The last two sentences describe the specific expression of the unique feeling: the sky is high and the air is cool, and the mind is open, and there is a crane flying thousands of miles in the clear sky, which is also consistent with his broad poetry. So as to set off the poet's happy mood. As Wang Fuzhi of the Qing Dynasty said in Jiang Zhai's Poems: "Write sorrow with music scenes, write music with sorrow scenes, and double their sorrow and joy." [1]
