The story of Dujiangyan

In the sixth year of Ding Yuan, Emperor Wu of the Han Dynasty (BC 165438+ BC 0 1), Sima Qian was ordered to visit Dujiangyan in the southwest. He recorded Li Bing's contribution to the creation of Dujiangyan in Historical Records of Rivers and Channels. Later generations built the West Station Pavilion and the West Station Hall in Minshan Mountain, which stretches to the west, as a memorial.

2. Zhuge Liang set up a soldier protection weir

In the 6th year of Jian Xing in Shu and Han Dynasties (AD 228), Zhuge Liang made a northern expedition, took Dujiangyan as the foundation of agriculture and an important pillar of national economic development, recruited 1.200 soldiers to guard it, and set up full-time weir officials for regular management and maintenance. This is the first time for later generations to set up full-time water conservancy officials to manage Dujiangyan.

3. Legend of Li Erlang's Dragon Descending

Legend has it that in ancient times, the Minjiang River was a dragon, and Jiro, the son of Li Bing, led the Seven Saints of Haishan to descend the dragon. After a fierce battle, the seven saints and the hounds and growling dogs were killed in the battlefield, and the dragon fled south with serious injuries. Jiro chased Qingcheng Mountain, disappeared from the dragon's sight, sat on a big stone to rest, and met an old woman.

The old woman knew that he was Li Bing's son. In order to urge Long to come here, she warmly received him, cooked noodles and invited him to dinner. Soon, the dragon in human form also came to the old woman's house and begged for food to satisfy her hunger.

The old woman saw at a glance that it was a dragon and cooked a pot of noodles for it. Who knows, when noodles reach the dragon's stomach, they all turn into chains with iron hooks, which lock the dragon from its stomach and make it yield easily. So far, there are two remains at the foot of Qingcheng Mountain: the "ass print" where Li Erlang sat and the "dragon rolling trough" where the dragon rolled.

Kyle Poirot went to Dujiangyan.

In the first year of Yuan Shizu to Zhengzheng (A.D. 1264 ~ 1294), Italian traveler Kelpolo rode from Hanzhong, Shaanxi, and arrived in Chengdu for more than 20 days, and visited Dujiangyan. Later, he said in the book "Travels of Kyle Polo": "The water system in Du Jiang is very urgent. There are many fish in the middle of the river, and there are many ships coming and going, carrying commercial goods, upstream and downstream."

5. Richthofen visited Dujiangyan.

During the Tongzhi period of Qing Dynasty (A.D. 1862 ~ 1874), German geographer Richthofen (Richthofen 1833- 1905) visited Dujiangyan and praised the perfection of irrigation methods in Dujiangyan with expert eyes, which was unparalleled in the world.

1872 set up a special chapter on Dujiangyan in Baron Richthofen's letter. Richthofen was the first person to introduce Dujiangyan to the world in detail. 1872, Richthofen praised "Dujiangyan irrigation method is perfect, chinese odyssey".

Extended information Dujiangyan is a world cultural heritage (listed in the World Cultural Heritage List by UNESCO in 2000), a world natural heritage (giant panda habitat in Sichuan), a national key cultural relics protection unit, a national scenic spot and a national AAAAA-level tourist attraction.

Dujiangyan is located in the west of Dujiangyan City, Chengdu, Sichuan Province, on the Minjiang River in the west of Chengdu Plain. It was built in the last years of Qin and Zhao Haoqi (about 256 BC-25 BC1year)? It is a large-scale water conservancy project organized and built by Li Bing and his son, the magistrate of Shu County, on the basis of excavating the turtle essence of predecessors. It consists of a fish mouth, a sand weir and a bottle mouth, and has been playing the role of flood control and irrigation for more than 2000 years.

Chengdu Plain has become a "land of abundance" with thousands of miles of floods and droughts. Up to now, the irrigation area has reached more than 30 counties and cities, covering an area of nearly 10 million mu. It is the oldest, only preserved and still in use in the world. It is characterized by water diversion without dam, which embodies the diligence, courage and wisdom of the ancient working people in China.

Dujiangyan Scenic Area mainly includes Fulongguan, Erwang Temple, Anlan Cable Bridge, Yuleiguan, Lidui Park, Leiyushan Park, Yunv Mountain, Lingyan Temple, Zhao Pu Temple, Cuiyuehu Lake and Dujiangyan Water Conservancy Project.
