Yangzhou in Tang dynasty

? In the Tang Dynasty, salt and iron transportation made people live in Yangzhou and took full charge of financial power. There are dozens of judges and businessmen coming and going. Therefore, the folk proverb says that "Yang Yi Er" is about the most prosperous in the world, with Yangzhou being the first and Yizhou, Sichuan being the second. Du Mu has a poem "Yangzhou Road is ten miles spring breeze, not as good as rolling beads curtain". In Hu Zhang's poem, he said: "Ten miles of long streets are connected, and the moonlight bridge meets the gods. Life only coincides with Yangzhou's death, and Zen Mountain cures the tomb. " Wang Jianshi said: "There are thousands of lights in the night market, and there are many people drinking tea in high-rise buildings. Now, unlike usual, the wanderer is singing and listening. " Xu Ning's poem said, "There is a moonlit night on earth, and there are hooligans in Yangzhou." The grand occasion at that time can be imagined. Since the battle between Bi Shiduo and Sun Ru, Yangzhou has been in ruins. Yang Xingmi rebuilt Yangzhou and gradually became a magnificent buffer region, but it was burned down in the later period of Zhou Xiande. In the Song Dynasty, it was peaceful 170 years, but it couldn't catch up with one tenth of the Tang Dynasty!
