Going into Guodengqiao and going out of Guozhou boat, the Red Mansion rises every year. The emperor forbore to lay down Chen's business and only changed Leitang to several mu of land. Emperor Yangdi of Sui Dynasty left us endless regrets all his life. The Sui Dynasty Mausoleum is a bit heavy. It's quite far from the city of Yangzhou. On the other side of Haojiang Huaisi, I took No. 25 bus and turned No. 303. After getting off, I had to run two miles. Looking back on the time when such an emperor, it can be said that he created Yangzhou, but later generations buried him alone so far, I feel really sorry.
