What are the interesting inventions in China?

To exaggerate, there are many cruel and interesting inventions in the history of China. These inventions have benefited the society and people, raised people's lives to a higher level and effectively solved the fundamental problems of people's livelihood. Here, I would like to thank the talented people who invented interesting props first, and then introduce three interesting inventions to you.

1. Seismograph

Seismograph? What is this for? Dig a hole in the ground? Haha, of course not. Seismograph is a measuring instrument. A long time ago, during the Eastern Han Dynasty, a famous man, Zhang Heng, invented a great creation. I read ancient books. I remember the origin of seismograph because there were too many earthquakes at that time, which caused great harm to people and society. Injuries, deaths, houses collapsed and trees had to be rebuilt. In order to reduce such losses, the clever Zhang Heng finally invented such an instrument, which is also the only one in history.

This instrument is very interesting and beautiful. It has eight directions, and each direction has a faucet. The faucets in eight directions are unified. It has a dragon ball in its mouth and a toad under it. Dragon balls and toads are in one-to-one correspondence. Suppose there is an earthquake on one side, the dragon ball contained in Longkou will fall into toad's mouth, which is very practical for earthquake prediction.

2. gunpowder

As we all know, gunpowder is one of the four great inventions. It looks ugly, but it can save or destroy the world, with infinite power! It really makes people love and hate.

How interesting is it? Gunpowder is made up of very small powder, which looks unremarkable at all, but it thunders when it is lit, just like an earthquake, which can destroy a house without manpower, hehe!

Has anyone ever asked who invented such a powerful thing? No, no, no, it wasn't invented by people. Gunpowder comes from alchemy and contains sulfur and saltpeter. It reacts with these chemicals and plays the role of explosion. Isn't it amazing and interesting? If you want to invent things like gunpowder, study chemistry well from now on!

abacus

Looking at the history books, it is Guan Yu who invented the abacus at the end of the Han Dynasty, but whether it was invented by Guan Yu remains to be verified. I think this invention can be compared with the four great inventions.

The abacus is an "able person" and an auxiliary tool for arithmetic. It takes a long time to calculate 1+999 by thinking with your head, breaking with your hands and counting with matchsticks, but now that you have an abacus, you can save time and effort. By the way, can you use an abacus? Many people don't. Oh, I will.

Tell me about the abacus. It is made of beads, so it won't hurt your hands when you move it. Very smooth. As long as the formula can be worked out, it will be worked out quickly. However, when calculating with an abacus, you should pay attention to your hands, eyes and brain, and you should not be distracted and cooperate closely. Quietly tell you, working with an abacus can exercise your brain and react faster.

The above three interesting inventions have been explained. In fact, there are many interesting inventions in the history of China, such as printing, compass and papermaking. If you are interested, you can go to Baidu to learn about it, and you can also stimulate your other potential.
