The world is looking up to this channel, reflecting what importance and why

The opening of the Grand Canal played an important role in the development of China's feudal economy. The canal was dug to dredge the river and promote the economic exchanges between the north and the south, which is not only conducive to the transportation of military supplies and civilian materials between the north and the south, but also conducive to drainage and irrigation.

The importance of the Grand Canal, because the opening of the Grand Canal, greatly promoted the economic exchanges between the North and the South.

It is the world's waterway transportation, all relying on this one canal. This sentence may say that the Beijing-Hangzhou Grand Canal At that time, the political and military center of the Sui Dynasty was in the north, while the economy of the Jianghuai region in the south had developed greatly. A large part of the materials needed by the northern cities, especially the grain, depend on the Jianghuai region**.

How to transport this grain to the north in a continuous stream is a major problem that must be solved before the ruling class. A large number of materials have to be transported from Jianghuai to Chang'an, and even to the military towns in the northern frontier. At that time, overland transportation consisted of mule, horse, cart and shoulder-carrying people, and the transportation speed was slow, the volume of transportation was small, and the cost and consumption were too large to meet the needs of the ruling class.

This task can only be accomplished by means of waterway transport.

This canal describes the Grand Canal of the Sui Dynasty, referring to the transportation function of the Grand Canal of the Sui Dynasty, which promoted the economic development of the north and south of the Sui Dynasty.

The Sui-Tang Grand Canal spans more than 10 latitudes of the earth, runs through the North China Plain and the southeast coastal area of the richest area in China, and spans Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, Jiangsu, Zhejiang 8 provinces and municipalities directly under the central government.

Key features:The main function of the Grand Canal in the Sui and Tang Dynasties was to transport water. During the Sui and Tang dynasties, the national granary was set up in Luoyang, and a large amount of grain from Jiangnan and other places was transported, and "boats came and went all day long, thousands of miles endlessly" on the canal.

By the time Wu Zetian was proclaimed emperor, the area around Beishi in Luoyang City was already "the world's boats and boats, often more than 10,000 ships", and the river congestion was too serious that even the empress could not sit still. In 701 AD, Wu Zetian ordered "to divert the canal and open a new pond to rent ships from the states".

The meaning of this sentence is that the country relies on the Grand Canal to transport grain by water.

That is to say, this canal is very important to the world's transportation! It should be talking about the Beijing-Hangzhou Grand Canal!

The meaning of this sentence is that the country relies on the Grand Canal to transport grain by water.

Explanation: In ancient China, under the condition that there were no railways, automobiles and other means of transportation, land transportation of grain could only be carried out by cars and horses, relying on manpower and animal power, and the transportation volume was small, the speed was slow, and the cost was large. Compared with land transportation, water transportation of grain has a large volume, fast speed and low cost.

It is the world's waterway transportation, all relying on this one canal.

Meaning: water transportation depends entirely on the Grand Canal. "Zhuan Cao" is Cao Yun, that is, using ships to transport grain and wages. "One Canal" is the Grand Canal.

The Grand Canal and the Great Wall are two ancient Chinese man-made structures, which are unique in the world. Generally speaking, the "Grand Canal" refers to the canal that runs from Beijing to Hangzhou from north to south, and is sometimes referred to as the "Beijing-Hangzhou Canal". But in fact, it also crosses the Qiantang River, passes through Shaoxing and Yuyao and goes directly to Ningbo.

Because the section south of the Qiantang River was dug very early, it is known as the "Zhedong Canal" and is often excluded from the Grand Canal.

The length of the Grand Canal varies greatly in statistics, with the more common being 1,780 kilometers. But this is only the length of the Grand Canal from Beijing to Hangzhou, not counting the more than 200 kilometers from the south bank of the Qiantang River to Ningbo, which are still navigable. So the actual length of the Grand Canal should be about 2,000 kilometers.

The Grand Canal is not only the pride of China, but also a precious heritage of mankind. It was excavated in sections from the Warring States period until the 14th century, and most of it is still playing a shipping role, and the effort spent by the ancient Chinese on design and construction is really unimaginably great.

After the completion of the Grand Canal, the capitals of the Yuan, Ming and Qing dynasties were all set in Beijing, and the south came and went, and the trees and oars were connected, which became the only shortcut for material transportation. This is of great value for the economic development of the provinces along the canal and a large area in the vicinity. For these three generations of imperial courts, the transportation of grain from the south to the north, that is, "Cao Yun", is particularly important, and is a necessary condition for the construction of the capital Beijing, so the imperial court attaches great importance to the protection and maintenance of the Grand Canal.

Therefore, the Ming Dynasty promulgated the "Eight Reasons for Traveling the River" for the "Grand Canal": "Because the river is not flooded and transported to the north, because the river is not frozen and returned to the south, because the wind is north and south for the transportation period, because the wind is downstream, because the river is safe, the embankment is repaired because of the river, because the river is dangerous, it is repaired along the embankment in winter and spring, and it is defended according to the embankment in summer and autumn." "This also illustrates the importance of the Grand Canal from another aspect.
