Zheng Guo Canal, people's first reaction, is a "Zheng" State built a canal, but, thinking so, just wrong, just like the title is so awkward, it is a Korean named Zheng Guo (not Smecta) built a canal for Qin State, what is going on, among them, what interesting stories, everyone patiently look down.
Zhengguo Canal, known as "the first canal in the world", is the earliest large-scale water conservancy project in Chinese history, which was built in 246 BC and took ten years to complete. The construction of this canal was originally a "tired plan" adopted by South Korea to protect itself, but the final result was a water conservancy project for the benefit of the world.
After the reign of Qin Shi Huang, who often asked you to make money, with the continuous advancement of the reform of the Shang Dynasty, the national strength of the Qin State was thriving, and in order to compete for hegemony in the world, it was inevitable to encircle and suppress the surrounding countries, and South Korea, which was more unlucky, had a special geographical location, and it happened to be a barrier to go out of the customs and compete for hegemony in the world. Therefore, because the "position" is not right, South Korea is constantly invaded and attacked by Qin, but unfortunately, the weak country has no diplomacy, although South Korea knelt down to Qin to beg for mercy, and even ceded land to seek peace, but the territory was constantly encroached upon by Qin.
In the ninth year of King Han Huan, Qin invaded again, and Korea was forced to cede Shangdang County. Shangdang County Taishou Feng Ting made his own initiative and gave the entire Shangdang County to Zhao State, Qin and Zhao broke out conflicts, triggering the Battle of Changping, and Qin will "kill the god" Bai Qikeng to kill Zhao Army 400,000, and King Han Huan was terrified.
I can't beat it, and when I "lick the dog" I have nothing. King Han Huan thought about it and held back a bad move!
He found Zheng Guo, a river worker, and gave him a task, asking him to take advantage of Qin's opportunity to recruit talents from all over the world to infiltrate Qin, find an opportunity to persuade Qin to build a canal that could cover the whole country, and use huge projects to exhaust Qin's manpower, finance, and material resources, so that it could no longer launch an attack on Korea.
Zheng Guo met Ying Zheng as he wished, and claimed that if Qin Shi Huang could reuse him and build a canal that could cover the whole country, then Qin's grain production would definitely increase by three to four times, and the Qin army would have no worries in the future.
You must know that in ancient times, the survival and development of a country depended on food. Ying Zheng is ambitious, and if he wants to dominate the world, he must solve the problem of grain and grass. And Zheng Guo's words made Qin Shi Huang see hope, so after careful consideration, Qin Shi Huang agreed to Zheng Guo's proposal.
In fact, as the king of Han envisioned, the construction of the Zhengguo Canal, a huge water conservancy project, caused the Qin state to invest so much time and money that there was no way to attack Korea.
From 246 BC to 238 BC, the Zhengguo Canal was not completed. Just when they thought that their plot was about to succeed, the identity of Zheng Guo's spy was revealed, and during the construction process, someone exposed Zheng Guo's identity as a spy. Qin Shi Huang was furious and planned to execute Zheng Guo. However, Zheng Guo was not afraid of danger and explained his point to Qin Shi Huang: although he was a spy for Korea, he was also an engineer who thought about the people. He was well aware of the benefits of building the Zhengguo Canal to the Qin state, so he hoped that Qin Shi Huang would continue to complete the project. Qin Shi Huang was moved by Zheng Guo's words and continued to support him in completing the construction of Zheng Guo's canal.
Ten years later, the Zheng Guoqu was finally completed, and the fact is just as Zheng Guo promised, Zheng Guoqu irrigated a large area of land in Qin, transforming those barren fields into fertile land, at that time Qin had 40,000 hectares of fertile land, equivalent to 1.1 million mu, a minute per mu, equivalent to 100 kilograms, and a total of 110,000 tons of grain in 40,000 hectares. According to historical records, in the Kanto region, where agriculture was more developed during the same period, the yield per mu was only 25 kilograms, which was a quarter of that of Guanzhong. As a result, the grain production of the Qin State is increasing, and every household can fill their stomachs.
The increase in production made the Qin State have a large amount of grain and wealth, laying a solid economic foundation for the Qin State to dominate the world, and the name of Zheng Guoqu is also to commemorate the merits of Zheng Guo.
On the basis of the two canals, the descendants continued to build new irrigation canals: 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, and the Longdong Canal in the Qing Dynasty. The Jinghui Canal, which still plays an irrigation function today, was built on the site of the Zhengguo Canal.
Because of the historical merits of Zheng Guoqu, in 2016, it was successfully selected as the "World Irrigation Engineering Heritage".
An irrigation canal that has benefited the people of Guanzhong for more than 2,000 years was unexpectedly triggered by a vicious spy plan. King Han Huan's practice of drinking water to quench his thirst has become a joke through the ages. He took the initiative to dedicate an immortal talent to the Qin State, which lacked river engineering experts, and also added a strong color to Chinese civilization.
