Presumably,Current Affairs many people are not unfamiliar with the "Yellow River Iron Cow", and even appeared in textbooks that year.In the 1980s, archeologists removed 4 iron cows from the Yellow River Basin in Yongji County, Yongji City, Shanxi Province, with a weight of 70 tons.As we all know, everything used in China before the Warring States Period was bronze utensils, and it was discovered that iron was not only lighter and easier to get than bronze during the Warring States Period, so it began to use widely.But the disadvantage of iron is easy to rust, but this also bought foreshadowing for iron cows.
In the 1940s, the local people's ships were scratched by hard objects on the Yellow River Ancient Road. At the same time, the local people had seen the behemoth exposed to the water. When this kind of scene was difficult to be valued in that difficult age.Until the 1950s, the Yellow River was affected by the terrain and moved westward. The riverbed began to reveal, and the behemoths that had been circulating in the local area finally "appeared".The archaeologists came to the news that after nearly a year, the location of the Yellow River and the cow and the method of salvage was finally determined.
The historical story of the Yellow River Iron Cow
It was cast in the 13th year of the Kaiyuan of the Tang Dynasty (725 years), and was cast in order to reinforce the local floating bridge vitamin system.In fact, iron cows not only have the role of fixed cable bridges in ancient times, but also have the meaning of "suppression". Just as the description of the Book of Changes in the Book of Changes is "Niu Xiangkun, Kun is the earth, and the soil wins.This meaning "Zhenhe Iron Cow" is used on the turbulent and turbulent Yellow River, giving the local people a sense of stability.
Many people should have doubts, how did such a heavy iron cow be placed in the Yellow River?In fact, it was not placed in Hanoi at first, but was cast by the river. Later, the Yellow River was involved in the river because of the flood of the Yellow River.It is also the evidence related to Tieniu that archaeologists discovered the Pujindu site. After thousands of years, the changes in the Yellow River bed also confirmed that the fact that the "Yellow River moved west" was nearly 3 kilometers.EssenceHowever, even though the river water was moved west, the riverbed still existed, and the craftsmen of the Tang Dynasty were shocked by the shocking casting technology.
In fact, at the time of the manufacturing of the floating bridge during the Kaiyuan period of the Tang Dynasty, the craftsman was 8 huge iron cows to act as a bridge pier. The iron cow head was east of the west, and the face of the river across the two rows.EssenceAt present, I just found 4 respects, and there are others to be excavated.It has always been placed without any protection measures, and at the same time does not run away, which makes the public expressed incomprehension.
Expert: We dare not dare
In fact, these four iron cows are as high as 70 tons each. It is currently the heaviest and long -term cultural relics found in my country. In addition, the experts have also discovered the "cow people" next to the iron cow, which adds up to the weight more. It's amazing.The excavation of Tieniu further made Chinese archeological causes further, but this also tested the technology of Chinese experts.However, the height of the iron cow is about 1.9 meters, the length of its body is 3 meters, and the width is 1.3 meters. Such heavy and large objects have huge difficulties on moving and moving bricks.It was difficult to recover the loss, so when the experts did not find a feasible strategy, they all said they did not dare to act lightly.
At the same time, it is not easy to find a sealed space for these behemoths to collect space. It is not easy to consume financial resources and manpower after looking for the right method, but subsequent collection is even more difficult.After a series of discussions by experts, I felt that the ironware was easy to rust and it was difficult to protect. Before finding a better way, the best way was to place the iron cow in place according to the soldiers.Many of them are worried that this is not only easy to damage the cultural relics without any measures without any measures.In fact, the experts have discussed the current plan and made the most reasonable arrangements with the knowledge of archeological majors.At the same time, such a behemoth is worried about transportation, so ordinary thieves also want to steal this treasure.
For the protection of iron cultural relics, it is still a worldwide problem. Even though countries around the world have developed rapidly in the archeological field, it is still difficult to protect the iron cultural relics that are prone to rust and oxidation.The advent of these four iron cows not only represents my country in the Kaiyuan years of the Tang Dynasty, but also the world's top in the world.Looking back at the iron cows stored on the same day, they have to admire the ancients' craftsmanship.At the same time, there are the wisdom of ancient people. The research of astronomical geography and the mastery of bridge technology have already understood the bridge with iron cows, and quietly let the river water diverted silently, which symbolizes blocking the flood and benefiting the people.
After thousands of years, it was completely hidden by the mud of the Yellow River, but it could not prevent it from showing the wisdom and practical side to modern people.Just like Wang Anshi's "Timber Music Rhymes Sixths of the First Hall of the Hall of the Paradise": "The century -old cultural relics are excellent, and the nation is like a cricket." Cultural relics are the treasures of the Chinese nation, and they are also witnesses and witnesses of civilization.Drivers.
