Elaboration: In Yang Di Yan's Family and Talking about the Tang Dynasty, there is a story about Yang Di going to Yangzhou to see Qionghua, but it was a great disappointment that Qionghua was blown down by the strong wind. In fact, it is to highlight the virtuous character of Qionghua. At that time, Emperor Yang Di took a dragon boat from the capital to Yangzhou, which was very important. Jiangnan has been divided for hundreds of years. Shortly after Yang Di incorporated Jiangnan into his own rule, it was a wise move to unite China to show his rule and attention to Jiangnan. Yang Di's move is not only a personal pleasure, but also an important measure to consolidate his rule.
