Pi Rixiu, a poet in the Tang Dynasty, once commented on the Grand Canal: "This river is formed when the Tao is exhausted, and it has been a thousand miles since then. If there is no water temple dragon boat, wouldn't there be more theories about * * *? " Although people say that the Sui Dynasty perished because of the opening of the Grand Canal, it still played a great role. If Emperor Yang Di had not taken a dragon boat in the Grand Canal, his achievements in building the Grand Canal could be comparable to that of Dayu. "
Hu Ceng, a poet in the Tang Dynasty, said, "When a long river opens, it will be sui in nine days. The brocade sail has not fallen, and the dragon boat has not returned. "
Li, a poet in the Tang Dynasty, once wrote a poem for the Grand Canal, saying: "Bianshui is most beneficial to the Huaihe River, and the harm of a foreign land is also harmonious. In the forty-three States in the southeast, it is this river that absorbs all the oil. "
