A Millennium Aristocratic Family Starting from the Shang Dynasty

Chapter 281 World Cultural Heritage
Li Bing and his son conscripted 20 people into labor in the Bashu land, and at the same time, they also levied 20 stone grain and grass to build Dujiangyan.Although Huai State's labor levy did not pay wages, it provided food and clothing.At the same time, hard labor will be levied during slack farming seasons, and hard labor will be levied during busy farming seasons. It is a crime for local people to perform hard labor.Of course, except in times of war or geological disasters.

Because the people in Sichuan were deeply affected by the flooding of the Minjiang and Tuojiang rivers, they were very happy when they heard that the Huai State was going to control the floods, and soon the 20 laborers were collected.

During this time, Li Bing and his son have personally traveled and surveyed various places in central Sichuan, and they have also won the recognition of many people.

Because the construction of Dujiangyan is a huge water conservancy project, in addition to these ordinary people, a large number of craftsmen are also needed.After all, many projects are directed by craftsmen.Li Bing specifically advised Wang Xu and asked to recruit [-] craftsmen from the crafts supervisor to help build Dujiangyan.Wang Xu supported the construction of Dujiangyan, and not long after, the craftsman supervisor sent five hundred craftsmen.

After everything was ready, the water conservancy project was officially launched.According to Li Bing's plan, they need to dig a gap in the mountains and rivers on the north bank of the Minjiang River so that the water of the Minjiang River can flow out of the gap.At the same time, the Minjiang River is diverted with the help of the Minjiang River Island.

Li Bing led people to reinforce and raise the Minjiang River and dredge the downstream river.The most critical thing is to divert the water of the Minjiang River through ditches, and then introduce the diverted river water through the ditches to the Chengdu Plain for drinking or irrigation.

Due to the special geographical environment of the Minjiang River, Li Bing took sand and stones on the Jiangxin Island in the middle of the river to build an embankment, forming a curved bend, dividing the river into two rivers, the inner and the outer.In this way, the Minjiang River is divided into four and six.When there are no floods, the Minjiang River water passes through the Inner River, but when a flood occurs, the river water passes through the Outer River, reducing the pressure on the Inner River.

The whole project is very difficult, such as digging a gap in Yulei Mountain. The stone in the remaining veins of Yulei Mountain is as hard as iron. The craftsmen used fire and water pouring methods and spent a lot of manpower and material resources to dig out more than 20 meters in a section of the mountain. The gap cuts off the mountains.

In order to build a dike at the center of the river, Li Bing used local materials to make wooden rafters and woven bamboo cages into them, which were filled with stones to strengthen the embankment at the center of the river.This method of using local materials not only reduces the difficulty of Dujiangyan's construction, but also facilitates repairs.Every year during the dry season, damaged areas can be replaced.

While building Dujiangyan, Li Bing and his son also built aqueducts simultaneously. The aqueducts were like spider webs, dividing the Chengdu Plain into small pieces, and the water from the Minjiang River was diverted into the Chengdu Plain by these countless ditches for irrigation. land.

The entire Dujiangyan project is very large, and the labor labor dispatched by Huaiguo has a time limit, and they will leave when the time is up, and then recruit other labor labor.Even during busy farming periods, Dujiangyan still needs to stop work.The entire construction site will maintain a population of more than 10 people all year round.

The construction of Dujiangyan took a long time, and Huai State needed to invest a large amount of grain and grass every year.However, although the construction has not been completed, the water diversion canal first built by Li Bing and his son can already divert water for irrigation, allowing a lot of land on the Chengdu Plain to be irrigated.

After seeing the success of the canal, the people in central Sichuan became more confident and supported the construction of Dujiangyan.After seeing the benefits, many large households and local wealthy families in Chengdu donated food and materials one after another.

After the completion of the Dujiangyan Irrigation System, it will be of greater benefit to them. Which of the wealthy families in these places does not have thousands of acres of land? Although it seems that they have been divided, they know how to operate it.

With so much land being irrigated, the annual increase in grain is not a small amount. Putting in a little grain and obtaining a stable water source to increase grain production, these people are very clear.

With the strong support of the Huai State, the Dujiangyan project took 13 years and was finally completed.The completion of Dujiangyan also minimized the floods in the Bashu area. The originally turbulent water of the Minjiang River was successfully tamed by humans. The situation of "human or fish" gradually disappeared, and a new chapter in human taming of nature was written.After the completion of Dujiangyan, floods in Bashu were reduced by 70.00%, and the probability of drought was also reduced by 50.00%.And because of the Dujiangyan irrigation canal, even if there is a drought, the Chengdu area will not be affected.

The Dujiangyan Irrigation Project employed hundreds of thousands of people and took 10 years to complete. At its peak, more than 13 people worked on the entire construction site, consuming millions of stones of food and grass.But the harvest is also satisfying. This water conservancy project has allowed millions of acres of grain fields in the Chengdu Plain to be irrigated.Historical records: 'The people live in peace, the people are in Yinfu, the industries are prosperous, the year is prosperous, the fertile fields are thousands of miles away, and the country is a land of abundance. '

[Your descendants appointed Li Bing and his son to preside over the construction of the Dujiangyan flood control and irrigation water conservancy project. This is the world's earliest and largest dam-less water diversion and water conservancy project. It has written a new chapter for mankind to transform nature. You have gained a lot of luck. 】

In the first year after the construction of the Dujiangyan irrigation system was completed, there was heavy rain in Bashu, and the water potential of the Minjiang River and the Tuojiang River soared. The surging river water was successfully diverted in Dujiangyan. The river is tamed here.

The whole of central Shu was not affected by the floods, and the Chengdu Plain had abundant grain and fodder piled up like a mountain, and the people were well-off.

Jinling, Qianyuan Hall.

Wang Xu looked at the report about Shu in his hand. The grain output of Bashu had exceeded that of the Nanyang Plain, and was second only to the Huaihe Plain.You must know that the Huaihe Plain has only reached this level after hundreds of years of development by the Huai Kingdom, and the land of Bashu has only been developed for how long.With sufficient food and floods under control, the population of Bashu region will undergo explosive growth.

The land of Bashu is already qualified to become another food and population base for the Huai Kingdom.

At the same time, Le Yi and Li Bing have carried out reforms and water conservancy construction projects in the land of Bashu for more than ten years, and they have also thoroughly sorted out the land of Bashu from top to bottom.Five years after Le Yi pacified Bashu, he was promoted to the position of Prime Minister of Huai State. At the same time, he was granted the title of King of An State, with a household of thousands of households, and his wife was granted the title of Lady of An State.

It is not a good thing for Le Yi to stay in Bashu for a long time. Wang Xu never tried to test people's hearts. After promoting Le Yi to Xiangguo, he appointed Xu Chao as the governor of Shu County and continued to cooperate with Li Bing.The land of Bashu was also completely controlled by the Huai Kingdom.

Dujiangyan is the oldest dam-less water conservancy and irrigation project in the world and has been in use for 2000 years. It cleverly uses the surrounding mountains and rivers to take advantage of the situation, so that this set of water conservancy facilities has water diversion, irrigation, flood control, and sand discharge. The most amazing thing about the effectiveness of this system is that it does not cut off water sources or destroy the natural environment, and achieves harmonious coexistence between humans and nature, which is worth learning from our descendants.

Dujiangyan is a national key cultural relic protection unit and is included in the World Cultural Heritage, World Natural Heritage, and World Irrigation Heritage. ——"Eighth Grade History Volume [-]·History of Ancient China"

It is hard to imagine that such a grand project as Dujiangyan was actually the work of the ancient Chinese more than 2000 years ago. At the same time, European civilization was still in the city-state period. What is even more difficult to understand is that ancient Babylon and ancient Egypt were still built for kings and pharaohs. While building palaces and mausoleums, ancient China actually spent a huge amount of manpower and physics to provide conveniences to the common people. Perhaps this is one of the reasons why among all ancient civilizations, only China can survive. ——"General History of the World·History of Ancient China"
