1, which is bulky and difficult to move;
2. Iron products are difficult to preserve.
To put it bluntly, staying there is the best way to protect the iron cow.
The iron cow that was fished up.
This iron cow was fished out of the muddy Yellow River in 1980s. They are called Kaiyuan Iron Cattle. We can know from their names that these four cows were cast in the Tang Dynasty. Do you still remember "Kaiyuan Shi Sheng" in the history textbook? Although it was cast in the Tang Dynasty, its technology is not inferior at all. Like the big live cow you usually see, it has big eyes and beautiful patterns carved on its forehead. This is a rare work of art in the world.

These iron cows were not made by people who had nothing to do in the Tang Dynasty. They are made for towns and rivers. Although our Yellow River is our mother river, we sometimes lose our temper and occasionally the river overflows. Dayu's water control is the Yellow River. Every dynasty had a headache because of managing the Yellow River. In order to protect the people around the Yellow River, Emperor Xuanzong of the Tang Dynasty ordered craftsmen to build eight big iron cows, and according to the Feng Shui arrangement, he put four cows on each bank of the river, and the situation really improved. After further iteration, the river course was also changed, so eight "Big Macs" sank to the bottom of the river. Four were not fished out until 1989.
Four big iron cows
The iron cow was fished out, and everyone was happy. It is rare that cultural relics can be found for so long, but experts are beginning to worry. These four iron cows, each weighing 70 tons, are 280 tons. Which museum do you think they can be put in? Moreover, these things are iron cows, not Taurus steel cows. Iron is very easy to oxidize, which is what we usually call rust. As far as the current situation is concerned, the iron cow is still quite good, and we have to praise the ancient people for their wonderful workmanship.
