Write a brief sentence about the feeling of visiting Dujiangyan

1. A brief comment on the one-day tour of Dujiangyan. On the way, my mother and I talked and laughed. I looked at the beautiful scenery outside the car and felt very happy. When I arrived in Dujiangyan, I felt more people. I went to Qingcheng Mountain at first sight.

We came to the mountain outside Qingcheng. The mountain outside Qingcheng is the same as that in front of Qingcheng. The environment inside is beautiful and quiet. The trees in the sky form a "primeval forest", which is memorable. There is only one scenic spot on the mountain outside Qingcheng-Zhao Pu Temple. There is a relatively large scale, and the temples are full of incense. Many people burn incense, worship Buddha and make wishes there. There is a thousand-year-old tree in the temple, 1500 years old. Its trunk is so thick that it takes three or four people to pick it up. Its crown is like a huge umbrella, blocking the sun and bringing us cool. We walked around the west of Shandong and were completely confused by the seclusion here. At noon, we slowly walked out of the mountain gate.

Out of Zhao Pu Temple, we came to Jiezi Town again. Jiezi Town is an ancient town in chongzhou city, which silenced our ancient culture in Sichuan. This town is full of antiques. There are many small shops on both sides of the street, some selling snacks, some selling wood products, some selling clothes and restaurants. Most of them sell soup and sesame seed cake, because the specialty here is the most famous soup and sesame seed cake. The store also said: "I am an authentic sesame seed cake, you can rest assured to buy it." Look, it says here ... "Anyway, it's very, very lively here. Let's go to a restaurant for dinner first. The food here is very delicious. There are many wild vegetables and many "green foods" on the mountain, which make people feel very comfortable.

With the winding mountain road, we came to Lingyan Mountain again. Lingyan Mountain is 5 kilometers away from Dujiangyan City, with an altitude of 1432 meters, which is higher than Qingcheng Mountain. We bought tickets and started climbing the mountain. Entering Lingyan Mountain, I saw many Woods composed of nanmu, ginkgo and pine trees, which covered the sky and made people intoxicated. Along the way, we talked and laughed and saw some rock climbing statues. When I came to the black wind tunnel, I thought there was an old demon from Montenegro. As a result, it is known from the introduction that there are black winds coming out of the cave in summer and autumn. I'm curious, just wait there for the black wind. After waiting for a long time, there was no black wind, and we left disappointed. At the top, there is a Lingyan Guanyin. Guanyin is golden, which is more noticeable under the sunlight. At this time, a cool breeze blew, and I felt particularly cool, so we went down the mountain happily. On the way down the mountain, we also caught three tadpoles in a small pond. That's the spring water on the mountain. It's cold. When we bend over, we feel as cold as ice. That tadpole is also very cunning. As soon as our hands reached the bottom of the pool, it was difficult to catch them. Uncle Wang carefully put his hand in, fished it out, and finally caught one and put it in my bottle. My mother also carefully put her hand into the water and caught a small one, so we caught three tadpoles. We went down the mountain happily with tadpoles.

At the end of the day, my mother went home happily with our "harvest"

The one-day tour in Dujiangyan is very short. On the way, my mother and I talked and laughed. I looked at the beautiful scenery outside the car and my heart was full of joy.

After reading Dujiangyan, I have a feeling that there is a Dujiangyan in the rest of my cultural journey. The article is not long, but Mr. Yu pursues the past and seeks the present, and draws lessons from it. He wrote a lifeless water conservancy project, full of flesh and blood, very vivid. After reading this article, I was deeply moved by Mr. Wang's flexible thinking and unique understanding.

The author first compares the Great Wall, which is regarded by many people in China as a national symbol, with Dujiangyan. He said, "I think the most exciting project in the history of China is not the Great Wall, but Dujiangyan." You can't help reading the article, because in most people's minds, the Great Wall is the symbol of our nation and the essence of our culture. Do you think that a suffering nation has built a Wan Li barrier between barren hills and deserts with manpower? What a nation this is, what a heavy history. But Yu Xiansheng pointed out, "Dujiangyan is not as magnificent as the Great Wall on the surface, but it is destined to benefit the Millennium steadily." "Its water flow is not as abrupt as the Great Wall of Wan Li, but penetrates and extends in turn, and the extension distance is not shorter than the Great Wall. The civilization of the Great Wall is a rigid sculpture, and its civilization is a life of wisdom. The Great Wall puts on a pair of old qualifications waiting for people to repair it, but it is very humble, like a country mother who never shows off and asks for nothing but dedication. " Here, Yu Xiansheng pointed out in vivid language that the Great Wall was dead and just stood there for a while, blown down by the wind and sand, waiting for people to rebuild it. Dujiangyan is not. It has stood proudly in the storm for more than 2,000 years, as solid as the history of China, and Dujiangyan's spiritual image is vividly on the paper. Through this lively Dujiangyan, we have to be moved by Li Bing and his son.

Yu Xiansheng believes that "since then, the practice of China's Millennium officialdom is to select a group of scholars. Their positions are bureaucratic and have no specialization, but Bing has become a practical scientist because of his official position. There are obviously two completely different political trends here. In Li Bing's view, the meaning of politics is seeking truth from facts, eliminating disasters, nourishing and nurturing. What it wants to achieve is both concrete and simple. He accepted a simple truth that even children can understand: since the biggest problem in Sichuan is drought and flood, the ruler of Sichuan must become a water conservancy scientist. " Obviously, the political ideal advocated by the writer "is to be rational, to eliminate disasters, to nourish and nurture", and like Li Bing "entered the clearest anthropological thinking with the thinking of the old farmer in the field". Therefore, he praised "he is stupid and smart." He is clumsy and clever. "In the writer's view, although" he didn't leave any life information, only left a hard dam for people to guess. "Compared with the famous Qin Huang Hanwu, he is not a hero, but he obviously stayed in people's hearts longer than Qin Huang Hanwu. In this regard, the writer wrote, "People come here and wonder again and again: Who is this? Died two thousand years ago, but he is still directing the current. Standing in front of Jiang Xin's sentry box, the shouts, exhortations and comforts of "you go this way and he goes that way" are endless. No one can live this long. "

Yes, while we admire the ancient people's idea of "harmony between man and nature" and their ingenuity in engineering design, how can we not be moved by their spirit of "smiling without mud and holding a long neck"? Isn't it with this spirit that the Chinese nation can stand up in the face of disasters again and again? As Mr. Yu said: "As long as Dujiangyan does not collapse, Li Bing's spirit will not dissipate, and Li Bing's son will be reproduced from generation to generation."

4. Describe Dujiangyan Sentence Huangyu's poem Dujiangyan: "The Minjiang River is far away, and the ancient pile is broken. Bourne is vast and connected with three Chu, and Huize frost moistens nine places. Rain falls in front of the axe rock, and light thunder thunders at the bottom of Longtan. Embankment construction does not dare to quit hard work, and bamboo and stone management is second-rate. "

Mr. Zhao Puchu wrote a poem praising the ancient weir, saying, "Suit the Great Wall and sing Qin. The Great Wall has been useless for a long time, leaving only historical sites. It is not as good as Dujiangyan, and the cross irrigation. "

He Qing Shengxin's poem "Fulongguan": "Ying Ying is separated by a river and two mountains. Red leaves flow in the broken stream and white clouds rise in the empty pool. The bridge cable is out of thin air, and the tree floats at dusk. Where is the dragon lady now? The cliff asked Liu Jun. "

Dong Qing Qin Xiang's "Ode to Guan Yu of Youlong": "Thunder and thunder in the gorge shook the blue end, and it has been broken for several years! Out of the ancient and modern Qin and Han dynasties, ask him if Long Fu has been cold? "

Haru Aoyama's poem "Guanyang Zhi Zhu Ci" wrote: "Dujiangyan is flooded and people are in a hurry to reach the shore. I like to watch the frequent withdrawal of rafts, and I am happy to say that I am plowing.

5. Visiting Dujiangyan Composition This summer vacation, our family traveled to Sichuan and visited Dujiangyan.

Dujiangyan is a famous water conservancy project in China, located on the Minjiang River in Chengdu, which was built by Li Bing and his son in the Qin Dynasty. Early in the morning, we set out from Chengdu, and after two hours' journey, we arrived at Dujiangyan.

When we arrived, it was raining in Mao Mao, and Dujiangyan in the rain was another beautiful scene. The water on the river is foggy, just like a girl wearing a scarf. As soon as I entered the gate, I walked along the stone road. On both sides of the road stand heroic statues of Dujiangyan in various periods, including Li Bing, Li Erlang and Zhuge Liang.

Into the showroom, there are all kinds of precious historical materials and cultural relics of Dujiangyan from more than 2,000 years ago to the present, and three magical projects of Dujiangyan are introduced: fish mouth, treasure bottle mouth and flying sand weir.

Walking out of the showroom, I heard the rumbling sound of running water in the distance, climbed up the pavilion along the steps and saw the "Treasure Bottle Mouth". The "bottle mouth" is inverted trapezoidal, and the stone wall is engraved with a "water gauge" to observe the water level. Li Bing spent eight years leading the general public to cut a big hole in the hard rock by burning, pouring water and pulling sledges.

It diverts the excess water flowing from the upstream from here, reducing the occurrence of floods. Looking down from above, it looks like the bottle mouth of a vase, so it is called "bottle mouth".

Out of the "treasure bottle mouth", across a bridge, came to the "flying sand weir". The ancient "flying sand weir" was made of cages and pebbles, and now it has been built of concrete. Its main function is to discharge sand and gravel washed down from the upstream, and the maximum stone it can discharge can reach about one ton, which plays the role of flood control, sand removal and disaster reduction. Further on, you will reach the "fish mouth", which is the first of the three major projects. It is triangular, just like a fish's mouth, and it is also an artificial diversion dike, which divides the turbulent river into two, four and eight.

Standing in front of the "fish mouth", from a distance, the turbulent river flows down the river, and after the diversion of the "fish mouth", the water flow becomes stable and slow. Here, I visited the whole Dujiangyan water conservancy project.

The three major projects complement each other and cooperate closely, which not only ensures the water demand of irrigation areas, but also greatly prevents and reduces the threat of floods, and has become a great pioneering work in scientific water control in ancient world history. Looking at such a spectacular and huge project, it was built with people's hands under the condition of underdeveloped science and technology more than 2,000 years ago, which fully demonstrated the wisdom and talent of the ancient people in China.

In the afternoon, I reluctantly left Dujiangyan. On the way, I thought: Our Chinese nation is really a great nation with splendid cultural heritage.

6. Imitating Dujiangyan Composition This morning, five of us drove to Dujiangyan, a world-famous city. On the way, it suddenly began to rain cats and dogs, which cast a shadow over the cheerful Inner Mongolia. When I arrived at my destination, I was relieved after the rain cleared.

The first thing you see is that Lidui Park was a famous "flower country" in the Song Dynasty and a "mulberry garden" in the Qing Dynasty. Gardens and pavilions in the park are strewn at random, with towering ancient trees, lush green trees, exotic flowers and different grasses, and different flower forms. The origin of "leaving a pile" is that when Li Bing was building Dujiangyan, in order to lead the Minjiang River water to western Sichuan and irrigate farmland, he artificially dug a diversion port next to it, separating the opposite Leiyu Mountain from a hill, forming an isolated pile.

Dujiangyan consists of three major projects: fishmouth diversion dike, flying sand weir and bottle mouth protection. First of all, the "Yu Zui Fenshui Dike" divides the Minjiang River into Waijiang River and Neijiang River. Flood discharge and sediment discharge in the outer river and irrigation in the inner river. Second, the "flying sand weir" discharges floods, sand and gravel, and blocks springs. It is a major feature that the Minjiang River water is continuously sent to the irrigation area during the dry season. Third, the "bottle mouth" is a narrow and deep trapezoidal water intake dug by hand. One is to divert water for downstream use, and the other is to cooperate with the Sha Fei weir to control the Neijiang flood from flooding into the Chengdu-Chongqing Plain and let the flood be discharged outside the river. These three major projects are interdependent and mutually restrictive, forming an organic whole. Because of drought and flood, western Sichuan became a "land of abundance".

Li Bing and his son overcame many difficulties and built Dujiangyan, which has been playing a great role in benefiting mankind for more than 2200 years. In the era of extremely underdeveloped science, making this great feat cannot be erased by the times and cannot be forgotten by people. In order to commemorate them, a temple was built, and the "Long Fu View" pinned people's thoughts. We learn from our ancestors their spirit of self-improvement. Study hard so as not to lose to our ancestors-we are hardworking and brave China people!

During the summer vacation, my mother took me to visit Dujiangyan Water Conservancy Project.

Dujiangyan is located on the river in the west of Chengdu Plain, Sichuan Province. Built in the 3rd century A.D., it is a large-scale water conservancy project built by Li Bing, the prefect of Shu County of Qin State in China during the Warring States Period. It is the oldest and only water conservancy project in the world, which is characterized by not building a dam to divert water. For more than 2200 years, it still plays a huge role.

On that day, the dark clouds in the sky were like cotton dyed with ink. After a while, it began to rain in Mao Mao. The drizzle is like silver hair swaying, like kite string shaking. But I'm not wet at all.

As soon as we entered the door, we came to Guanlan Pavilion, where we saw the magnificent scenery of the ancient weir. Looking down at his feet, Jiang Tao is tumbling and pouring bottles. The whole Dujiangyan presents a magnificent picture of "Long dragons walking on the ground and the Milky Way flowing in the sky". Walking down the steps of Guanlan Pavilion, you came to Erwang Temple, which was called Chongde Hall in ancient times. It was built in 494-498 AD to commemorate Li Bing, the builder of Dujiangyan Water Conservancy Project.

After the Song Dynasty, Li Bing and his son were made kings and renamed the Erwang Temple. You see, the stairs in the temple turn back to the city wall, the pavilions are scattered and the eaves are tiled, majestic and solemn.

The temple is completely dependent on the natural geographical environment and built on the mountain, and the architectural style does not emphasize the symmetry of the central axis. In the main hall and the back hall, there are colored sculptures of Li Bing and his son and statues of "Yan Gong" in previous dynasties, which are vivid in carving and exquisite in skill.

Li's formula is also engraved on the stone wall in the temple: "Dig deep into the stall and make a weir low". Strolling in the meantime, it seems to have entered the "first capital".

After visiting the Erwang Temple, we boarded the Anlansuo Bridge, which is about 500 meters long. The Anlansuo Bridge is known as one of the five ancient bridges in China, also known as the "Couple Bridge", which was built before the Song Dynasty. The cable bridge is supported by concrete piles, with thick steel cables across the river, wooden boards as the bridge deck and bamboo cables as the columns on both sides.

Finally, I crossed the scary An Lan Lock Bridge and came to Dujiangyan's three major projects ―― fish mouth, flying sand weir and treasure bottle mouth. Let's start with the fish mouth. It's like the mouth of a fish. According to the tour guide, its setting is very clever. It skillfully uses the terrain and topography to complete the task of water diversion, and plays the role of automatically adjusting the water quantity at different water levels in high and low seasons.

Our ancestors were very clever. When the flow is small and water is scarce, in order not to waste 40% of the flow of the outer river, the outer river is cut into Neijiang by crossing the river to make the spring ploughing water in Neijiang irrigation area more reliable. The long dike under the fish mouth, that is, the dike that divides the internal and external rivers, is called Jingang dike.

The lower section of the dike is opposite to Hutou bank on the left bank of Neijiang, and there is a low-level section. Spring, autumn, winter and three seasons are the smooth roads for people to travel between Lidui Park and Suoqiao. During the flood season, waves splash here, which is the spillway of Neijiang. Spillway was named "Shilangyan" and "Jindi" in the Tang Dynasty, and was later called "Jianshui River". Because of its remarkable function of flood discharge and sediment discharge, it is also called "flying sand rock".

Sha Fei Weir looks ordinary, but its function is great, which can be said to be the key to ensure that the Chengdu Plain will not be flooded. The main function of the flying sand weir is that when the water in Neijiang exceeds the upper limit of the flow of the bottle mouth, the excess water will overflow from the flying sand weir itself; In case of catastrophic flood, it will burst its banks by itself and let a large number of rivers flow back to Minjiang River.

Another function is "flying sand". The Minjiang River runs down the mountain, carrying a lot of sediment and stones. If they are allowed to enter Neijiang, the bottle mouth and irrigation area will be blocked. Sha Fei Weil is really an understanding and hard to get rid of. It is wonderful to throw the sediment and pebbles brought by the upstream, even the boulder weighing 1000 kg, into the outer river from here to ensure the smooth flow of Neijiang.

At the other end of the fish mouth is the fish tail, diagonally opposite to the bottle mouth. It is a cutting mouth that extends to the long ridge in front of the Minjiang River, and it is a throat that is artificially dug to control the incoming water in Neijiang. Because it looks like a bottle mouth and has peculiar functions, it is named Bao bottle mouth. The mountain on the left and right of the bottle mouth is called Guan, which is a temple dedicated to Li Bing, because it is separated from the mountain.

Fulongguan was originally a "Fan Xian Pavilion" built in the Jin Dynasty to commemorate Qingcheng hermit. Because Li Bing succumbed to the dragon and fell under the pile, Li Bing was sacrificed in the early Northern Song Dynasty and named "Fulongguan".

Walking into Fulongguan, I saw Fulongguan hanging on three sides and connected with the open dam with stone steps, which made Fulongguan look particularly majestic. The original Fulong view was twofold. Later, due to the completion of Li Bingdian, * * * had a triple main hall.

There are many cultural relics in Fulongguan. The stone statue of Li Bing of the Eastern Han Dynasty standing in the main hall was unearthed in the foundation pit of the Third Bridge in 1974 when the cable bridge was moved.

Carved from gray sandstone, it is 290 cm high, 96 cm wide at the shoulder and 46 cm thick, with extrusion at the bottom. Stone crown gown, hands on chest, smiling, sleeve skirt has a shallow inscription.

Behavior: "Therefore, Li Fujun in Shu County is afraid of ice"; On the left is "Shuidu Oak Silver Dragon on the fifth day of the leap month in the first year of Jianning"; The weir stone statue erected on the right side of the main hall was discovered in June1975+1October 18 during the protection excavation of the beach below Dujiangyan. The head of the stone statue has been washed away and the back has been seriously eroded. Experts infer that it may be one of the "three gods" in the inscription of Li Bing's stone statue.

The dragonfly iron tripod in the main hall is a relic of Princess Yu Zhen, the daughter of Emperor Rongzong of Tang Dynasty. The tripod weighs about 1000 kg and has eight dragons and moire flowers on it. It is a rare ancient casting.

Fish mouth, flying sand weir, treasure bottle mouth and other projects may feel ordinary and simple in our view, but we don't know that they contain extremely great scientific value. Today, the system contained in it is still at the forefront of contemporary science and technology, and is widely praised and used. However, these scientific principles have been applied to practice in Dujiangyan water conservancy project many years ago. This is really a symbol of ancient civilization in China, and it is also the pride of us in China.

It's getting late, and we reluctantly left Dujiangyan, which is the crystallization of China's wisdom, civilization and scientific creation-a bright pearl in the history of world water conservancy. I think: In the great process of mankind marching towards 2 1 century, Dujiangyan will certainly show her more brilliant new posture.

There is a temple, Long Fu Temple, dedicated to Li Bing. Fulongguan was originally a "Fan Xian Pavilion" built in the Jin Dynasty to commemorate Qingcheng hermit.

Because Li Bing succumbed to the dragon and fell under the pile, Li Bing was sacrificed in the early Northern Song Dynasty and named "Fulongguan". Walking into Fulongguan, I saw Fulongguan hanging on three sides and connected with the open dam with stone steps.

8. praise Dujiangyan 1 in one sentence. Dujiangyan water conservancy project is unparalleled in the world.

I think the most exciting project in the history of China is not Dujiangyan, but Dujiangyan.

3. The Dujiangyan project is wonderful and beneficial to Sichuan, which shows that the working people in China have great power to give orders.

14. Dujiangyan is another feat of human beings to transform nature.

Dujiangyan is a great legacy left by the ancients.
