-Su Shi's "Dream on the 20th day of the first month in Jiangcheng Ziyin" means that two people have been dead for ten years, but they are at a loss to meet each other. I don't want to miss myself but I can't forget it.
At the mouth of the lake, looking at Lushan Waterfall, Zhang Jiuling is full of red springs and the atmosphere is half purple. Run down the miscellaneous trees and return to the clouds. The sun is like a rainbow, the sky is clear, and the wind and rain are hard. Hukou is Poyang Hukou, and Jiangzhou Town in Tang Dynasty is under the jurisdiction of Hongzhou Governor. This poem was written in the secretariat of Ren Hongzhou, Zhang Jiuling, and was transferred to the secretariat of Guizhou. Zhang Jiuling had a tortuous experience before. In the 11th year of Kaiyuan (723), Zhang said that he was the prime minister, and Zhang Jiuling was highly valued. He was introduced to his family and gave birth. In the 14th year of Kaiyuan, Zhang was dismissed because Taigong was young. Soon, it was Jizhou secretariat again. He went to a state in the south of the Yangtze River to take care of his elderly mother in his hometown. Emperor Xuanzong of the Tang Dynasty "made him superior, changed Hongzhou to Guizhou, and still served as the provincial judge of Lingnan Road" (Biography of Zhang Jiuling in Old Tang Dynasty). It was a tortuous experience, which made him have an indissoluble bond with the imperial court. Suddenly losing the dependence of the prime minister, but getting the favor of the emperor shows that his talent and morality have stood the test.
To this end, he is full of ambition and skillfully expresses this feeling in his poems. This poem describes the scene of Lushan Waterfall. It takes a rough outline from different angles, uses different techniques, writes the appearance and appearance, emphasizes the color and pen and ink, renders the contrast, compares the mountains with the sky, and writes the magnificent prospect of Lushan Waterfall. But joy is greater than joy, there are people in the scene, there is sound outside the image, the rhythm is stretched, and the artistic conception is melodious. People admire the scenery and feel sorry for themselves, writing landscapes and expressing their feelings, which shows the poet's portrayal of himself everywhere. Poets appreciate waterfalls and highlight their momentum, charm, spirit and realm. The first couplet is about the waterfall falling from the high Lushan Mountain. From a distance, it seems that it took half a day to come. "Towering" is the height of the mountain, "far" is the distance of the sky, and the momentum falls from the sky in an extraordinary way, while "red spring" and "purple atmosphere" set each other off and are dazzling.
