He Yu and the others took a car to the Dujiangyan parking lot, and the three of them followed a tourist group..

When they saw that Dujiangyan was very spectacular, they listened to the tour guide’s introduction while walking;

"Dujiangyan is located on the Minjiang River in the west of the Chengdu Plain.

It is composed of the head hub of the canal, including Yuzui, Feishayan, and Baopingkou."

Speaking of this, the tour guide pointed to Yuzui, Feishayan, and Baopingkou one by one. The bottle mouth introduced it, and everyone said after reading it:"It's so vivid."

The tour guide went on to say,"The water diversion channels at all levels in the irrigation area, various engineering buildings, large, medium and small reservoirs and weirs constitute a huge engineering system. The head of the canal covers an area of ​​more than 200 acres. It is responsible for the irrigation of more than 10 million acres of farmland in 7 cities and 40 counties in the central and western Sichuan Basin, as well as the water supply for many key enterprises in Chengdu and urban domestic water supply.

As well as comprehensive services such as flood control, power generation, water rafting, aquaculture, breeding, forestry and fruit trees, tourism, and environmental protection, it is an irreplaceable water conservancy infrastructure for the development of the national economy in Sichuan Province.

In the later period of King Zhao of Qin, from 276 to 251 BC,

Li Bing, the governor of Shu County, summarized the experience of previous people in water control and organized the people on both sides of the Minjiang River to build Dujiangyan. In the Tang Dynasty, Feishayan was built."

The tour guide pointed to Feishayan and said,"It's just an important project to discharge river sand."

The tour guide continued,"After the founding of the People's Republic of China, industrial water supply canals, Waijiang Gates, and Feishayan industrial water diversion temporary sluices were built.

To be effective , To manage and maintain the operation of Dujiangyan, a weir official and annual maintenance system has been established.

Dujiangyan is the oldest and only remaining grand water conservancy project in the world characterized by diversion without dams.

It makes full use of the local geographical conditions of high in the northwest and low in the southeast.

According to the river The special topography, water veins, and water potential at the exit of the mountain pass take advantage of the situation to divert water without dams and provide gravity irrigation, making embankments, water diversion, flood discharge, sand discharge, and flow control interdependent and forming a system.

This ensures flood control, irrigation, water transportation, and Give full play to the comprehensive benefits of social water use.

The greatest thing about it is that it has been built for more than 2,250 years and is playing an increasingly important role.

Dujiangyan is an important part of the world cultural heritage and the world natural heritage.

World Irrigation Project Heritage, a national key cultural relic protection unit, a national scenic spot, and a national AAAAA tourist attraction."

After listening to the tour guide's introduction, He Yu said;"Fortunately, we encountered the detailed introduction of the tour guide on the tour today, which opened our eyes. It has added a lot of knowledge.

It shows that the intelligence and wisdom of the ancients were extraordinary.

Otherwise, let us look at just a few rivers"

"You are right. Without listening to the tour guide’s introduction, I only know that Dujiangyan is famous.

Now after listening to it, I really understand why Dujiangyan is famous.

Li Bing is really not simple.

But I heard you say that Dujiangyan was built by Li Bing and his sons.

But the tour guide didn’t introduce it!"Teacher Zhang asked

"The tour guide will not introduce you, maybe he wants to keep something secret.

When we go to the Erwang Temple, there are statues of Li Bing and his son.

After Li Bing ascended to heaven, there were still some projects. It was his son who continued to consolidate and complete it.

Look, the cable bridge on the Minjiang River was originally made of rattan. It was built by Li Bing's son.

Later it was changed into an iron rope."He Yu said

"How do you know it was built by Li Bing's son?"Teacher Yang asked、

"Of course I know, otherwise you wouldn’t call me an all-rounder!"He Yu said with a smile

"You know everything. Let me ask you, I heard that there is no Erwang Temple, only the City God Temple."Teacher Yang asked

"The plaque above the temple door says City God's Temple and does not say Erwang Temple. But in the temple, there are statues of Li Bing and his son.

I call him Erwang Temple and it is worthy of its name.

This is called touching the scene and triggering feelings!

If you don’t believe it, I’ll take you to see it later."

It's true:

It's so rare to join a tour group without paying any money, and the tour guide's introduction is so wonderful.

It's worth visiting Dujiangyan to increase your knowledge and open your eyes.
