Which project that benefited the country and the people affected China for more than two thousand years, so that he finally became a fairy?

This great project is Dujiangyan Water Conservancy Project, and it was built by Li Bing and his son. Li Bing spent his whole life building water conservancy projects, and spent more than eight years on this project. After Dujiangyan was completed, he went to build other water conservancy projects, and finally he died from overwork in his job. His great spirit of benefiting one side of the people was honored by later generations and built a temple by local people.

Dujiangyan is located in the west of Dujiangyan City, Chengdu, Sichuan Province. Dujiangyan, a water conservancy project, was started at the end of Qin Zhaowang. It has been more than 2, years since then. Although time has passed for a long time, people and things have changed in those years, Dujiangyan is still playing the role of flood control and irrigation, making this basin in Sichuan a land of abundance. Now its irrigation area has reached more than 3 counties and cities, with an area of nearly 1 million mu.

In more than 2 years BC, Li Bing was appointed as the prefect of Shu County by Qin Zhaowang, but the natural environment in this area was very bad at that time, especially the geographical environment at that time led to an extreme natural environment in Shu County, that is, it was either very dry or waterlogging, which made the local people miserable. Every rainy season, a lot of water would surge from Minjiang River, and there was no water conservancy project to stop it in Chengdu Plain.

Faced with this harsh natural environment, Li Bing and his son decided to build a large-scale water conservancy project after some investigation. The main works of this project include a water diversion dike, an spillway and a water intake. The overall planning of Dujiangyan is to divide the water in the Minjiang River into two parts, one of which is introduced into the Chengdu Plain. It took more than eight years for this project to be completed. Li Bing and his son led the local people to work tirelessly to build this project day and night. After eight years, the Dujiangyan water conservancy project was finally repaired. After the repair, the project can drain the flood in time in rainy days and irrigate the farmland in dry days. Since then, the fields of ordinary people have finally achieved drought and flood protection. People are very grateful for the contributions of Li Bing's father and son. After his death, later generations built temples for him to commemorate his great achievements, including the Great King Temple and the Second King Temple. Since then, Li Bing has been called the Lord of Sichuan by later generations, and the people are all grateful for his contributions. It is also a local custom to worship Li Bing every year.
