Are there any cultural relics 1500 years that prove that China is ahead of Europe and America in science and technology?

The folk story is about the moire bronze bull lamp unearthed in the tombs of the Eastern Han Dynasty, which is ahead of western science and technology in environmental protection 1500 years. The core of moire bronze bull lamp is ordinary lamps, after all, electric lamps were not invented at that time. But using kerosene lamp, the smoke after burning is a very troublesome thing for people. This lamp solves the problem of kerosene lamp smoke.

The moire bronze bull lamp is a thing with a buffalo-shaped base, and the buffalo's stomach is full of water. The buffalo carries a kerosene lamp on its back, and the vent of the kerosene lamp is connected with the buffalo's horn. The horn is hollow and connected with the belly of the buffalo, so that when the kerosene lamp is lit, the smoke will reach the belly of the base buffalo along the horn, and then the pungent smell of smoke will be filtered out by water, thus creating a sense of environmental protection.

Although strictly speaking, this so-called smoke has no impact on the environment, it has a great impact on users. Western European and American societies only solved this problem in15th century, which is why China's science and technology is ahead of Europe and America 1500 years. Unfortunately, this statement is a bit reluctant. After all, the so-called environmental protection kerosene lamp is too limited to reflect the real gap between the two sides from people's lives.

In fact, in addition to this moire bronze bull lamp unearthed from the Eastern Han Dynasty tomb, there are many things that can prove that China's technology is more developed than Western Europe in history. For example, people used soap to wash clothes in ancient times. In ancient times, people didn't use this fragrant soap to wash clothes, and it was particularly unclean, especially in the west.

The earliest use of soap in western Europe? Urine? Go and wash. Yes, that is, people urinate everywhere. In ancient times, the west had to collect it. Urine tax? Yes! And China used the fruit of Gleditsia sinensis? Gleditsia sinensis and plant ash are kneaded into a ball to make simple soap. As you can see, the manufacturing process is rough, but in fact, the core is the same as the soap used now!

Generally speaking, there is no doubt that China's ancient science and technology is ahead of Europe and America in many aspects. Otherwise, the ancient Tang Dynasty would not have become the center of the world, and Zheng He's voyage to the West in the Ming Dynasty would have become a joke.
