We all know that as the mother rivers, the Yangtze River and the Yellow River, stretch for a long time and give birth to Chinese children. However, we all know that because of the backwardness of science and technology in ancient times, flooding in the Yangtze River Basin and the Yellow River Basin was also frequent, resulting in no harvest of crops and displacement of people. Of course, in order to ensure the people's peace of mind, many water conservancy projects have also been built in various dynasties and generations. Among them, we are most familiar with the contemporary water conservancy project "Three Gorges Dam", as the world's largest water conservancy and power generation project "Three Gorges Dam" has long been famous in the world, has become a symbol of national strength. However, in today's rapidly changing science and technology, the development of science and technology is beyond our imagination, but thousands of years ago, the backwardness of scientific productivity, coupled with the lack of labor, large water conservancy projects can be said to be unimaginable projects. However, the wisdom of the ancients is also beyond our imagination, and in the history of the Yangtze River Basin and the Yellow River Basin, world-famous water conservancy projects have also been built.
Among the ancient water conservancy projects on the mainland, the one we are most familiar with and also the world-renowned is that after more than 2,200 years, the Chengdu Plain has become a "country of heavenly capital" with water and drought from people and fertile fields, and it is a rare treasure of the ancient water conservancy projects on the mainland, with flood control, irrigation and shipping - Dujiangyan. Of course, in 246 BC, the Zhengguo Canal, which was built by the Korean hydraulic worker Zheng Guo in the Qin State under the auspices of the Qin State, is located in today's Jingyang County, Shaanxi Province, as a great project built by the ancient working people, it belongs to the earliest large-scale water conservancy project built in Guanzhong, and in 2016, it successfully applied for the World Irrigation Engineering Heritage and is famous all over the world. There is also China's earliest multi-head irrigation project, the Zhanghe Canal built by Ximen Leopard in the early Warring States period.
For these historical water conservancy projects, we are all familiar with it, but there is a Dujiangyan, Zhanghe Canal, Zhengguo Canal and called the four major water conservancy projects in ancient China can be described as quite embarrassing, since it can become one of the four major water conservancy projects in ancient China, its role will naturally not be lost to others, but it is rarely known, the reason is very simple, that is, its name is often called wrong, resulting in its popularity is also greatly reduced, it is located in the territory of Shou County, one of the first batch of national historical and cultural cities in Anhui Province - Peony.
If there is no first time to explain, but directly see "Qianpi", I believe that the vast majority of people will read "sháo pō" at the first time, because we are most familiar with these two pronunciations, but after looking up the dictionary, we found that it was originally a polysyllabic word, here is the pronunciation of "què bēi". It is precisely because many people often call it by the wrong name, resulting in little knowledge even as the four major water conservancy projects in ancient mainland China. Although the name of Qianpi is often wrong and its popularity is relatively low, its historical value is not lost to other water conservancy projects.
First of all, let's understand Qianpi, the ancient name of Qianpi, today's name is "Anfeng Tang", which was built by Chu Xiangsun Shu'ao in the Spring and Autumn Period, which has a history of more than 2500 years, more than 300 years earlier than Dujiangyan and Zhengguoqu, and is a veritable "oldest water conservancy project in Chinese history". Anfengtang, as the earliest large-scale irrigation project in the history of China's water conservancy, did not be hastily trouble because of the backwardness of scientific productivity in ancient times, but under the auspices of Chu Xiangsun Shu'ao, through scientific site selection, reasonable engineering layout, make full use of abundant water sources, build embankments to block the mountain source river water originating from the north side of the Jianghuai watershed, and control more than 1,300 square kilometers of the Weidong Plain, and its engineering and water control concept and water control level are ahead of schedule.
In ancient times, when scientific productivity was backward, the completion of Anfengtang provided valuable experience for the large-scale Pitang water conservancy projects in later generations. After more than 2,500 years, In irrigation, shipping, Tuntian Jijun and other aspects, AnfengTang has played a major role, and to this day, as a famous large-scale irrigation project in the history of the mainland, it still plays a significant irrigation benefit, with an irrigation area of more than 70,000 hectares, still benefiting the surrounding people.
For the name "Qianpi", we are not very familiar with it, and it is likely that it will be called wrong. But as Anfeng Tang, I believe that everyone will not be unfamiliar, although it is a new name, but it is Qianpi, and it was successfully selected into the list of World Irrigation Engineering Heritage in 2015 with this new name. Whether it is Qianpi or Anfengtang, its name is an indelible name in the history of the mainland!
