From scratch After the peak of Caoyun, why did it decline in the end?

Because Caoyun developed and grew more and more powerful, harming the interests of the imperial court, the imperial court naturally had to rise up to suppress it, so it declined.

It is caused by various political and social reasons, the emergence of shipping has changed the status of Cao Yun, so that people have more choices, relatively speaking, sea transport is more convenient, and gradually replaced Cao Yun.

Because Caoyun relied on a large amount of manpower, the emergence of mechanization later, did not require too much manpower, and Caoyun declined.

What factors led to the eventual decline of Caoyun, and what is the best strategy now.

Cao Yun was once a very important mode of transportation in Chinese history, but there were many reasons for its eventual decline:1The development of rail and road transport will make transport more convenient, faster and more economical.

2.The development of the port has enabled the better development of Haitan Zhengyun and inland waterway transportation. 3.

The construction, maintenance and management of the Cao Canal and water conservancy projects are ineffective. 4.Internal corruption and institutional deficiencies.

5.In modern times, foreign powers have forcibly occupied sea power, so that the foreign world no longer depends on the internal transportation of the Shisong River. Nowadays, in order to solve the problem of water transportation, the following measures can be taken:

1.Improve the Cao Canal channel, improve water conservancy facilities, and improve the efficiency and safety of Cao Canal. 2.

We should strengthen the building of the management system, improve the level of management, and crack down on corruption. 3.Use modern scientific and technological means to improve the level of informatization and intelligent management of Caoyun logistics.

4.Promote the coordinated development of water transport and other modes of transportation, form complementary advantages, and improve the multi-return macro intermodal transport mode. 5.

Relying on the cultural tourism resources along the line, the development of Caoyun cultural tourism products and increase the added value of Caoyun.

The origins of Caoyun are very early.

After the Western Han Dynasty established Chang'an as the capital, it was necessary to transport a large amount of grain from the Guandong region every year to meet the needs of the nobles, officials and troops in the Guanzhong region.

In the passage of Cao, the cost is huge, it takes a long time, and there is a lot of manpower to mobilize, especially the danger that the Cao boat has to pass through the Sanmenxia Pillar of the Yellow River.

In addition to transporting from east to west, the Sui Dynasty also transferred from the Yangtze River basin to the north. Emperor Yang of the Sui Dynasty mobilized a large number of manpower to dig the Tongji Canal, connecting the three major water systems of the River, Huai and Jiang, forming a new transportation channel connecting the north and the south, and laying the foundation of the Grand Canal in later generations.

The Tang, Song, Yuan, Ming and Qing dynasties all attached great importance to Cao Yun, and for this reason, they dredged the network needed for the south-to-north grain transfer and established a Cao Yun storage system. Xianfeng five years (1855) the Yellow River diversion, the canal shallow stalks, river transportation increasingly difficult, with the development of commodity economy, Cao Yun is no longer necessary, Guangxu twenty-seven years (1901) Qing ** then ordered to stop Cao Yun. In the past dynasties, Caoyun ensured the grain needed by the military and civilians in Beijing and the north, which was conducive to the unification of the country, and because of the transportation of grain and commercial goods, it was conducive to the communication between the economy and commodity circulation between the north and the south; However, it is also a heavy burden on the people, and the cost of freight is too high, especially in the case of conscription, which is both requisitioned and distributed, and the service is long, so that the agricultural time is wrong, so there are also many drawbacks.

In 486 B.C., Wu Wangfu ordered to dig a deep ditch in Hancheng to divert the water of the Yangtze River to the north into the Huai River, communicate with the Jianghuai, and transport grain and troops by water. The excavation of the ditch was entirely for military purposes, and this was the beginning of the Cao Yun. Because the original purpose of Cao Yun was to transport military rations.

Later generations also called Hangou "Shanyang Blasphemy".
