In ancient China, the birthplace of Chinese civilization was mainly in the present north; but from the Tang and Song dynasties, the South became more and more attractive. Although most of the south was not developed in the early days, with the progress of civilization, the south gradually became a beautiful south.
This is still the case until today.
During the late Tang Dynasty, the economic development and resource development of the South had reached a certain level. At the same time, the North was caught in war, and many people went to the South to avoid disaster. And this goes, many poets do not want to go back.
Because, the beauty of Jiangnan captured the hearts of the poets. And see:
Everyone said that Jiangnan is very good, so tourists only want to stay in Jiangnan. The spring water is clearer and greener than the blue of the sky, and you can sleep on a painted boat that is raining outside. The woman who sells wine in the Jiangnan cellar is very beautiful. When selling wine, when the sleeves are filled with wine, the exposed wrists are as white as frost and snow. Don't go back to your hometown until you are old, otherwise you will regret it because of the war in your hometown.
