2. After more than 200 years of division, China has once again moved towards reunification and ushered in a prosperous and open era.
3. Since ancient times, the traffic between north and south is inconvenient; After the reunification of the Sui Dynasty, the political, economic and cultural contacts and exchanges between the North and the South need to be strengthened. In order to consolidate the achievements of reunification, it is necessary to strengthen control over the northeast and southeast regions; The affluence of the Sui Dynasty provided a solid material foundation for digging the Grand Canal. Of course, I think Emperor Yang Di can enjoy the scenery of the north and south more freely by digging canals.
4. The need of political and economic development
There is a saying that the sin of Emperor Yang Di lies in the present and his contribution lies in the future. It shows that there are good and bad things about Yang Di's grand canal, but 1 connects the five major river basins of Haihe River, Yellow River, Huaihe River, Yangtze River and Qiantang River, which strengthens the communication between North and South, promotes economic and cultural development and strengthens national unity.
6. During the reign of Emperor Yangdi (Emperor Wendi of Sui Dynasty), he was diligent in governing the country, determined to innovate, reformed political institutions, attached importance to selecting talents, vigorously developed agriculture, reduced taxes and corvees, and advocated frugality, which made the Sui Dynasty become a prosperous country and a prosperous society in a short time. During the reign of Emperor Yang Di (in fact, he was quite good when he first succeeded to the throne), he dug canals.
7. This question should be the same as the first one.
8. The excavation of the Grand Canal is not only navigable, but also connected with the water system, combined with water conservancy reform and development, so as to promote the benefits and eliminate the disadvantages, protect the ecology and not cause adverse effects. Moreover, in some areas, especially in southern Jiangsu, relying on the canal, a splendid Jiangnan has been formed.
For more than a thousand years, the benefits of the Grand Canal have been enduring, which is enough to prove its success.
In water conservancy projects, the ancients advocated the unity of heaven and man, which did not violate the laws of nature and was worth learning today.
9. Zhuo Jun refers to Beijing and Jiangdu refers to Yang (this is definitely an accurate answer, believe me).
