After the completion of Zheng Guoqu, what is the end of Zheng Guo

Zheng Guo was sent by Koreans to Qin to repair the water canal, the purpose was to consume the national strength of the Qin State, so that it could not annex the Seven Kingdoms, and when the water canal was about to be completed, the Qin State discovered Zheng Guo's identity and wanted to put him to death.

Zheng Guo defended that if he was executed, no one would repair this canal, and this canal was indeed useful to the Qin State, making Guanzhong fertile for thousands of miles, and it was not conducive to absorbing talents, so the King of Qin did not kill him and was able to die well in the Qin State.

Zheng Guo was sent by Koreans to Qin to repair water canals. to consume the national strength of the Qin State. so that it is powerless to annex the Seven Kingdoms ...

When the canal was about to be completed, Qin Guo discovered Zheng Guo's identity. I want to put him to death. Zheng Guo said that if he was put to death, no one would repair this canal.

Moreover, this canal is indeed useful to the Qin State, making Guanzhong fertile for thousands of miles. It is also not conducive to attracting talents. So King Qin didn't kill him.

To be able to die well in the Qin State...

It's purely hand-hitting.

His uncle!! Zheng Guoqu is supervised by a person named Zheng Guo, it is a trick used by South Korea in order to consume the Qin State, and he thinks he is very smart, but it only makes South Korea prolong the life of a few years, but it makes Guanzhong fertile for thousands of miles, and Qin Guo has become a merit for all generations, in fact, Ying Zheng has discovered this small conspiracy in the later stage, but after weighing it, he feels that he is more advantageous, and that's it.

Of course it's good, or it wouldn't be called "Zheng Guoqu".

Zhengguo Canal is a large-scale fortification built in the Qin State, and the construction process is laborious and costly, but after the successful construction, it has played an important role in the livelihood and development of the Qin State. It greatly increased the national strength of Qin.

The state of Qin did not kill him. Raised him.

Because the excavation of the Zhengguo Canal cost a lot of money, it led to the poor life of many people.

Zheng Guoqu. In the last years of the Warring States period by the Qin State.

Piercing. In 246 BC (the first year of the reign of King Qin), it was built under the auspices of Zheng Guo, a Korean hydraulic engineer, and was completed about ten years later.

At the end of the Warring States Period, Qin's national strength was thriving, and it wanted to have something to do in the East, and South Korea bore the brunt. In order to avoid being destroyed by Qin, South Korea sent Zheng Guo, a famous water conservancy engineering expert, as a spy into Qin and persuaded Qin to be in Jingshui.

and Luoshui to build a large irrigation channel. It is really a "tired Qin" policy. After seeing through it, Zheng Guochen took the pros and cons, and the king of Qin ordered Zheng Guo to repair a canal for irrigation. Qucheng Qin King ordered this canal to be Zheng Guoqu.

The historical role of Zheng Guoqu:

The role of Zhengguo Canal is not only that it has exerted irrigation benefits for more than 100 years, but also that it is the first to open up the irrigation of Jing and have a far-reaching impact on the irrigation of later generations. After the Qin Dynasty, successive dynasties continued to improve its water conservancy facilities here: successively through the Baigong Canal in the Han Dynasty, the Sanbai Canal in the Tang Dynasty, the Fengli Canal in the Song Dynasty, the Wangyushi Canal in the Yuan Dynasty, the Guanghui Canal and the Tongji Canal in the Ming Dynasty.

Qing Dynasty Longdong Canal and other channels of the past dynasties.

There was a folk song in the Han Dynasty: "Where is the field?" Ikeyo, Taniguchi.

Zheng Guo is in front, and Baiqu is behind. Lifting a gong is a cloud, and breaking a ditch is rain. Jingshui is a stone, its mud is several buckets, and irrigation and dung, and I grow a millet.

Food and clothing, the mouth of billions. "What is praised is the diversion project. Guanzhong, Shaanxi Province in 1929.

There was a major drought, and there was no harvest for three years, and hunger was everywhere. Irrigation is urgent.

Mr. Li Yizhi, a well-known water conservancy expert in modern China, was ordered to resolutely take up the heavy task of repairing the Jinghui Canal on the site of Zhengguo Canal. Under his personal auspices, the canal broke ground in December 1930, and thousands of migrant workers worked hard for nearly two years to finally build the Jinghui canal today. In June 1932, water was released to irrigate the fields, and the water diversion was 16 cubic meters per second, which could irrigate 600,000 mu of land.

Since then, it has continued to benefit the people.

Zheng Guo presided over the construction.

The Zhengguo Canal was dug by the Qin State in the last years of the Warring States Period. In 246 BC (the first year of the reign of King Qin), it was built under the auspices of Zheng Guo, a Korean hydraulic engineer, and was completed about ten years later. Zhengguo Canal, a great project built by the ancient working people, belongs to the earliest large-scale water conservancy project built in Guanzhong, located on the north bank of the Jing River, 25 kilometers northwest of Jingyang County, Shaanxi Province today.

It diverts Jing water in the west and injects Luo water in the east, which is more than 300 miles long.

Historical significanceZheng Guo Canal Project, west from the west foot of Zhongshan Gukou (now northwest of Chuantou Village, Wangqiao Township, northwest of Jingyang, Shaanxi), Zheng Guo made a stone weir dam in the valley to raise the water level and intercept Jing water into the canal. Taking advantage of the topography of slightly high in the northwest and slightly lower in the southeast, the main trunk line of the canal stretches from west to east along the southern foot of Beishan, flows through Jingyang, Sanyuan, Fuping, Pucheng and other counties, and finally flows into the Luohe River in the south of Jincheng Village, Pucheng County. The total length of the trunk canal is nearly 300 miles.

Along the way, the mountains and rivers are cut off, and the smelted water, clear water, turbid water, and Ishikawa water are collected into the canal to increase the amount of water. In the northern part of the Guanzhong Plain, an irrigation system like a spider's web is formed between Jing, Luo, and Wei, so that the Guanzhong Plain, which is high in drought and lacks rainfall, can be irrigated.

Zheng Guoqu did not disappear, but was forgotten by the dynasty.

After the completion of the Zheng State Canal, the Qin state became rich and strong, and finally annexed the vassal states. Although there is no evidence to directly prove that it was caused by the construction of Hangou, it is an indisputable fact that there were only four years from prosperity to decline.

The Zhengguo Canal in the Qin State was used directly to irrigate farmland and increase grain production, while the Han ditch was used directly for warfare, whether abolished. At present, there are three dark holes in the north and south of the Zhengguo Canal site, that is, the introduction of the Zhengguo Canal. Each dark cave is 3 meters wide and 2 meters deep, and there are obvious traces of white ash masonry outside the south cave.

Seven large earth pits began to appear on the ground from northwest to southeast in an oblique row, and the original underground trunk canal was communicated between the soil pits, so it was called "well canal".

The Zhengguo Canal Project, which is rare in the history of water conservancy in ancient China, has reasonable design, advanced technology and remarkable practical results, and is also rare in the history of water conservancy in the world.

01 Zheng Guoqu has been obliterated, but it has always attracted people's searching eyes. In the winter of 1985, Qin Jianming of the Shaanxi Provincial Cultural Relics Protection Center came to the Jing River, and finally found the missing Zhengguo Canal, which is located between Liquan Wanli Village and Shangran Village in the area of the Gukou of the Jing River, and was called "Tiger Ridge" by the locals, which is the site of the head of the Zheng Guoqu more than 2,000 years ago. At this point, Zheng Guoqu, who had been lost for thousands of years, finally surfaced.

At the end of the Warring States Period, the history of our country developed in the direction of establishing a single country, and some powerful vassal states wanted to unify the whole country with themselves as the center. If Qin wants to have something to do with the East, South Korea will bear the brunt of the attack, and South Korea is so weak that it is vulnerable. In desperation, King Han Huan adopted a very clumsy so-called "tired Qin" strategy, using the famous water conservancy engineer Zheng Guo as a spy, and traveled west into Qin, lobbying Qin to dig a large irrigation canal between Jingshui and Luoshui.

At that time, the war of annexation between countries was very fierce, and it was the military that fought the war, but the economic power supported the war. During the Warring States period, the agricultural economy was in a dominant position, and in order to be invincible in the war, it was necessary to vigorously develop agriculture and increase grain production to meet the needs of the long-term war. The Qin State originally wanted to develop water conservancy, and Guanzhong was the agricultural base of the Qin State, so it quickly made this suggestion, and immediately collected a large amount of manpower and material resources, and appointed Zheng Guo to preside over the construction of this project.

The project began in the first year of Qin Wangzheng (246 years ago), and was completed after more than ten years of hard work, and was called Zheng Guoqu.

After the completion of the Zheng State Canal, the Qin State became rich and strong, and finally annexed the vassal countries. Although there is no direct evidence to prove that the state was exhausted because of the construction of the ditch, it is an indisputable fact that it only took four years from strength to decline. The Zhengguo Canal of the Qin State was indirectly for war, and its direct use was to irrigate farmland and increase grain production, while the Hangou was directly for war both in terms of conceived and practical use.

At the site of Zhengguo Canal, there are currently three dark holes arranged in the north and south, namely the water inlet of Zhengguo Canal. Each dark hole is 3 meters wide and 2 meters deep, and there are obvious traces of destruction of white ash masonry outside the south entrance. On the ground, there began to appear seven large earth pits arranged diagonally from northwest to southeast, and the original underground trunk canal was communicated between the rest of the earth pits, so it was called "well ditch".

The enormity, rational design, advanced technology, and remarkable effectiveness of the Zhengguo Canal Project are rare in the history of water conservancy in ancient China and rare in the history of water conservancy in the world.

OriginalZheng Guoqu. It has been abandoned, and later, the Jinghui Canal was built on the site of Zhengguo Canal, which can divert water for irrigation and benefit one party.

Zhengguo Canal, a great project built by the ancient working people, belongs to the earliest large-scale water conservancy project, located in today's Jingyang County.

25 kilometers northwest of the Jing River.

On the north bank, the Zhengguo Canal was built in the reign of King Qin. Now Zheng Guoqu has become a national cultural relics protection unit.

November 8, 2016 in Chiang Mai, Thailand.

The 2nd World Irrigation Forum and the 67th International Executive Council brought good news that Zhengguo Canal was successfully inscribed on the World Heritage List and became the first World Irrigation Engineering Heritage Site in Shaanxi Province.

Historical Site Details:

Flows through Bupyeong. The Zhengguo Canal, with a total length of about 150 kilometers, can irrigate more than 180,000 hectares. From the diversion to the main canal, there is an aqueduct embankment with a width of 15 20 meters, a height of 3 5 meters and a length of 6 kilometers.

The existing Zhengguo Canal Mouth, Zhengguo Canal Ancient Road and Zhengguo Canal Barrage, there are the canal heads and trunk road ruins that have been rebuilt and repaired in the past dynasties after the Qin Dynasty, and there are a large number of stele remains.

After the completion of the Zhengguo Canal, the irrigation area reached 2.8 million mu, which was the largest irrigation canal in ancient China, making the Qin State.

Economically, we have completed preparations for the war to unify China. At the site of Zhengguo Canal, it was found that there are three dark holes arranged in the north and south, namely the water inlet of Zheng Guoqu Diversion Jing.

Each dark hole is 3 meters wide and 2 meters deep, and there are obvious traces of white ash masonry outside the south entrance. On the ground, there began to appear seven large soil pits arranged diagonally from northwest to east, and the original underground trunk canal between the soil pits communicated, so it was called "well ditch". The enormity of the Zhengguo Canal Project, the rationality of the Xiangbian travel plan, the advanced technology, and the remarkable effectiveness are rare in the history of water conservancy in ancient China and rare in the history of water conservancy in the world.

246 BC

According to historical records, during the Warring States period, Korea was the eastern neighbor of Qin. At the end of the Warring States Period, among the seven kingdoms of Qin, Qi, Chu, Yan, Zhao, Wei, and Han, Qin's national strength was thriving, and it was South Korea that bore the brunt of something in the East. In 246 BC, King Han Huan, in a desperate situation, adopted a so-called "tired Qin" strategy.

He used the hydraulic engineer Zheng Guo as a spy and sent him to Qin, lobbying Qin to dig a large irrigation channel between Jingshui and Luoshui, ostensibly to develop Qin's agriculture, but the real purpose was to exhaust Qin's strength.

However, after the completion of the Zhengguo Canal, the irrigation farmland could reach more than 40,000 hectares, making the Guanzhong Plain, the base camp of the Qin State, a fertile field, and the strength of the Qin State increased greatly, laying a solid foundation for the later unification of the Six Kingdoms.

The Zhengguo Canal was built by the Qin State during the Warring States Period. It was built under the auspices of the hydraulic engineer Zheng Guo, so "Zheng Guo" is a person here, not a country.

Zhengguo Canal was the first large-scale water conservancy project to be built in Guanzhong, which was dug by the Qin State at the end of the Warring States Period, and was built by Zheng Guo, a Korean hydraulic engineer, in 246 BC (the first year of Qin Shi Huang), and was completed about ten years later. It is located on the north bank of the Jing River, 25 kilometers northwest of today's Jingyang County. It diverts Jing water in the west and injects Luo water in the east, which is more than 300 miles long (the irrigation area is claimed to be 40,000 hectares).

Qin State Lü Buwei wanted to get the financial power in his hands, and South Korea wanted to delay the invasion of the Qin army, so he hit it off!

In the Qin Dynasty, it was built during the reign of Qin Shi Huang and was built under the auspices of Zheng Guo.

Built by the State of Qin. Zheng Guo is the name of the initiator of this canal.
