In Jiangnan in October, the weather is so bad and the winter scenery is like spring flowers. Poor means that the weather in Jiangnan is fine in October, and the scenery in winter is still full of spring. In October, the south of the Yangtze River is very different, and the winter scenery is like spring flowers, which comes from the seven-character rhyme of Bai Juyi, a poet in the Tang Dynasty. Original: 10, the weather in the south of the Yangtze River is fine and cold as spring flowers. The frost was light and did not kill the grass. Yellow sand in the desert, dry at the beginning of the warm day, old leaves are yellow like tender trees, and cold cherry branches are wild flowers. At this time, I was envious of the idlers being drunk, and five horses entered the restaurant for no reason.
