The Development Of Yangzhou In Tang Dynasty And The Formation Of The Term "Yang Yi Yi Er"

"Yang Yi Yi Er" is a statement that reflects the prosperous scene of Yangzhou and Chengdu in the Tang Dynasty.The formation of this statement is not only closely related to the development of its own economy,but also closely related to the improvement of the overall status of Yangzhou after the An-Shi Rebellion.Under the combined influence of these two factors,not only did the Tang people's evaluation of Yangzhou have changed significantly,but Yangzhou' s position in the minds of the Tang people has also gradually improved.It is also in this process that the "Yangyi"argument is gradually formed.After the generalization and refinement of Song Dynasty people,the theory of "Yang Yi" has evolved into the theory of "Yang Yi Yi Er" which was generally accepted by people in the Southern Song Dynasty.In other words,“Yang Yi Yi Er" was created on the basis of the development and status of Yangzhou in the Tang Dynasty.
