Experience of playing Dujiangyan 1
This summer vacation, I went to many places in Sichuan, Wuhou Temple, quiet Qingcheng Mountain, Du Fu Caotang, Erwang Temple and Qingyang Palace, but Dujiangyan impressed me the most.
Early that morning, our group got on the bus of the travel agency and arrived at the gate of Dujiangyan. At this time, just before dawn, the guide took us in.
After walking for dozens of meters, I saw a fountain. Surrounded by slender bamboo baskets filled with pebbles, there are several tripod-like things made of wood and fixed with ropes. It is said that Li Bing and his son used these two things to stop the water. There are four or five thick and long stakes in the middle of the fountain. According to the tour guide, in ancient times, the sand and gravel at the bottom of the river were cleaned every year. Li Bing used this stake as a marker. After digging the stake, he stopped digging. Until now, there are such stakes under the river.
Moving on, the tour guide led us to the fish mouth and crossed the weir road. On both sides of the weir road were bronze statues of twelve heroes who built and protected Dujiangyan.
We walked forward from the back, and not far away, we first saw the "buckle mouth" that divided a mountain into two parts. The water between the two parts flows to Neijiang, and the excess water flows to Waijiang. Most of the water used in Chengdu comes from Neijiang. Further on is the "flying sand weir", whose main function is to discharge flood and sediment. Neijiang river is very clean after flying sand weir. Just when I was feeling the greatness of the ancients, I came to the "fish mouth" unconsciously. Because its front looks like a flat fish mouth, it is named fish mouth, and it is here that Minjiang River is divided into Neijiang River and Waijiang River.
On this trip to Dujiangyan, I saw the cleverness of children in China. They made bamboo baskets and tied small stones together to increase their weight so as not to be washed away by water. Tripods and things like that use the stability principle of triangles. As I said before, it takes a long time to dig a mountain in two, but the ancients knew that it would take a long time to dig a mountain slowly, so they burned the stone first and then watered it immediately, which made the stone burst when it contracted rapidly, not only
I really admire the perseverance, determination and wisdom of Li Bing and his son. We should learn from their perseverance.
Dujiangyan Play Experience II
Dujiangyan is located in the west of Dujiangyan City, Chengdu, Sichuan Province, by the Minjiang River. This great water conservancy project built by Li Bing 236 years ago still plays a great role today. I was lucky enough to visit it during the Spring Festival this year. Its majesty and the wisdom of the ancients really surprised me.
In fact, everything in Dujiangyan was explained by the tour guide there, which made me realize the greatness of the ancients more deeply. Dujiangyan is the only dam-free water diversion project still in use in the world, which makes us far ahead of other countries, which also makes me full of pride when I visit.
Dujiangyan's main project consists of three parts: Yu Zui Fenshui levee, Feishayan spillway and Baojiangkou water intake, which are mutually beneficial and benefit thousands of Chengdu people.
Among them, I think the construction process of the bottle mouth is the most difficult and vivid. To repair this bottle mouth, you must cross a mountain called Lei Yu. Before the invention of gunpowder at that time, ice thought of the method of "expanding with heat and contracting with cold". First, put Yamakaji in, and then pour the cold river water on it. The mountain is easy to cut, and the process takes a long time. However, the river has been reasonably distributed and people have used it reasonably.
Next, we visited the next main project-"Fish Mouth". After the completion of the water diversion project in Baokou Port, although it has played a role in water diversion and irrigation, there is a high terrain where it is difficult for the river to pass through Baokou Port. Li Bing and his son decided to build a diversion weir in the upper reaches of Minjiang River, which would divide the river into two parts, one part of which would flow downstream and the other part would be forced to flow into the bottle mouth. Because the front end of the diversion weir looks like a fish head, it is also called "fish mouth".
In order to further control the water quantity, Li Bing built a flat water tank and a "flying sand weir" next to the bottle mouth to ensure that there would be no disaster in Neijiang. There is a bend in front of the spillway, and the river forms a circulation. When the river exceeds the crest of the weir, the debris flow in the flood center will enter the outer river and will not block Neijiang and Baokou Port, hence the name. This is the last major project I visited.
Dujiangyan may be unnecessary and easy to build in the eyes of modern people, but it was built more than 2000 years ago, and every project was hard-won, not to mention how many generations it has benefited! Dujiangyan is really the crystallization of ancient wisdom!

On the National Day, my parents and I went to Chengdu to celebrate the National Day with my grandpa, grandma and uncle. On the 4th, my family came to visit Dujiangyan, a great water conservancy project in ancient China. Before Dujiangyan was built, Chengdu was often flooded because of the Minjiang River flood, but it was short of water in dry season. So in 256 BC, Li Bing and his son built Dujiangyan with the people, which solved this problem.
Dujiangyan includes three major projects: Baokou, Sha Fei Weir and Yuzui. First of all, we came to Baokou, which is named after the shape of a bottle mouth. Its function is to introduce excess water from Minjiang River into Sichuan Plain, which can not only reduce floods, but also provide people with life and irrigation. Then we came to Sha Fei Weir, which was built to prevent large and small stones from blocking the bottle mouth. Then we walked on and came to the fish mouth. Because it was built like a fish mouth, it was called the fish mouth. The function of the fish mouth is to divide the water in Minjiang River into two parts, one part flows into Waijiang River and the other part flows into Neijiang River, thus greatly increasing the amount of water flowing into the bottle mouth. Next to the fish mouth is an iron cable bridge across the Minjiang River. Walking on it, overlooking the surging river below, really makes people feel a little scary. After crossing the iron chain bridge, we came to the Erwang Temple, which was built by later generations to commemorate Li Bing and his son. The Erwang Temple was built on the mountainside of Lei Yu, which is very magnificent. Walking out of the Erwang Temple, we climbed the steps to the top of the mountain and could see the whole picture of Dujiangyan. What a beautiful view!
After visiting Dujiangyan, I think the ancients could build such a great water conservancy project with their own hands without machines, and it was not bad for more than two thousand years. How clever the ancients were!

My hometown is Dujiangyan. With beautiful scenery and pleasant seasons, it is a famous tourist attraction.
In Dujiangyan, there is Qingcheng Mountain, a Taoist holy land that is "quiet in the world"; There is a famous water conservancy project-Dujiangyan, which "irrigates and divides fertile fields". 2500 years ago, Li Bing led people to build Dujiangyan project, which consists of three parts: fish mouth, flying sand weir and bottle mouth. The fish mouth is named after it looks like a fish mouth, which mainly plays a role in dividing water; Flying sand weir is to throw the river sand stones washed down from the mountain out of the river in flood season to avoid siltation of the river. The bottle mouth of the treasure is the entrance of the river into thousands of miles of fields, so it is named after its shape.
Summer is the busiest season in Dujiangyan. The city's unique water conservancy project, the Minjiang River water flowing through the bottle mouth is divided into five parts in the city. It's really cool under the cool river wind. Every evening, especially on Friday afternoon, crowds of cars flock to Dujiangyan, and the river suddenly becomes lively. It's really pleasant for people to punch in and drink, or to have tea and chat in groups of three or five.
Dujiangyan at night is more beautiful. The streets are brightly lit; On the river bank, neon lights are flashing. Walking into the bustling crowd is like walking into a fairyland on earth.
This is my hometown-Dujiangyan.
Dujiangyan play experience 5
Passing through Chengdu during the summer vacation. I was very tired after the long journey, so I left in a hurry to get some fresh air. I didn't have the idea of going to Dujiangyan, but when I heard that the car wouldn't start in the afternoon, I made up my mind. Forget it. Let's stop by and have a look!
Walking all the way, suddenly there was a rumbling noise in the distance, as if the world was shaking because of it. There was a fresh water vapor on my face, and my fatigue was swept away at this time, as if there was a magical force driving me to speed up my steps.
Finally arrived in Dujiangyan. Standing in Fulongguan and looking ahead, I was suddenly surprised. I saw the waves rolling and the turbid waves were sky-high. The river in the distance roared to the shore like a runaway wild horse. After colliding with the shore, it made an earth-shattering and thunderous noise. The river changed direction and then hit the other side, but it was forced to turn around obediently ... I finally saw that the river was not a runaway wild horse, but a good tamed horse. It operates according to the wishes of the dam designer. During the whole process, not a drop of water splashed in the wrong direction. Here I can feel the vitality of life and see the spectacular tame. You can see the mountains, the fog and the pine, and you can't forget Dujiangyan.
I wonder who tamed it. This has to mention Li Bing, the prefect of Shu County thousands of years ago.
Qin's original purpose may only be to prepare for the unification of the world. But Li Bing regards the construction of Dujiangyan as a flood control irrigation project. He is stupid and clever, clever and clumsy. He used the thinking of the old farmer in the field to enter the simplest thinking in the world. The completion of Dujiangyan made the originally arid Chengdu Plain the richest land at that time. After him, many books on water control have long been too simple to understand, and the eight-character mantra he summed up is still dripping.
I think that for thousands of years, many officialdom in China have risen rapidly, but few people really care about the whole world like Bing.
It is recorded in the Han Dynasty that the statue standing in the middle of the river is Li Bing himself. Whether it is true or not, I think historians know best what Li Bing wants, and that is the best position for Li Bing. Li Bing's deeds undoubtedly enlighten us on how and where people should stand.
