Yes, I don’t dare. After this big iron bull was salvaged ashore, it had been severely corroded. Moreover, this big iron bull was too bulky and difficult to move. Because it was made of iron, it was easily oxidized, so it was simply placed outdoors.
This iron bull was fished out of the muddy Yellow River in the 1980s. They are called Kaiyuan Iron Bulls, and these eight Iron Bulls were cast during the Tang Dynasty. Although it dates from the Tang Dynasty, the casting technology is not bad at all. These eight big iron bulls are just like the big live bulls we usually see. They have big, round eyes and beautiful patterns engraved on their foreheads. They are very rare works of art in the world.
These iron bulls had a very high status during the Tang Dynasty. They were used to suppress bridges on the river. We all know that the Yellow River will overflow during the rainy season. Once it causes floods, it will be a very terrible thing. Not only now, but every dynasty in the past also had a headache in managing the Yellow River. In order to protect the people around the Yellow River, Emperor Xuanzong of the Tang Dynasty ordered craftsmen to cast these eight large iron oxen. According to Feng Shui, four cows were released on each side of the river, and the situation did improve after they were released. As the times changed, the river course also changed, and slowly these eight big iron oxen sank to the bottom of the river. It was not until 1989 that four of the iron bulls were salvaged.
When they saw these iron bulls, the archaeologists were very happy, because it is rare to find cultural relics of such a long time. But experts are also worried because these four iron bulls are huge and very heavy. Each head weighs 70 tons, max. 280 tons. No museum can accommodate them, and they are too heavy to carry. Plus, they're all cast from iron, which oxidizes easily. Experts have no better way to solve this problem, so they can only place these giants outdoors.
