Du Mu's Shang Shan Ma Jian in Tang Dynasty. The whole poem is: the clouds are pale blue all around, and there are more than ten weeping willows. Pheasants flying deer are far away from the grass, and Niuxiang is full of chickens in spring. Xiumei's father is drinking and Xixiu's daughter is drinking wild flowers. I looked at the dust meter myself and was disappointed with the fine sand by the stream.
Creative background: In the fourth year of Tang Kaicheng (839), Du Mu was awarded the left vacancy, and the history museum was revised, and he will go to Beijing to work. Before the early spring, he sent his brother Du _ from Xuanzhou to Xunyang (now Jiujiang, Jiangxi), and in February he went back to Hanshui of the Yangtze River, passing through Nanyang, Wuguan and Shangshan to Chang 'an.
