When it comes to our four major inventions in China, it should be that no one knows them. Don't say that China's little friends, even foreigners know a little about them. But in ancient times, in addition to the four famous inventions, there are actually many great inventions. Some of them can not only bring more convenience to people's lives at that time, but also reflect that. People's wisdom at that time, today, I followed the editor to take stock of the five anti-sky technology in ancient China.

Ground Motion

An instrument for measuring earthquakes made by Han scientist Zhang Heng. The ground motion instrument was cast from bronze. Eight dragons were cast around the instrument body, and they were arranged in eight directions: east, south, west, north, southeast, northeast, southwest, and northwest. The faucets are connected to the engine in the internal channel, and each faucet has a small copper ball in its mouth. Pointing at the dragon's mouth on the ground, squatting eight copper toads, holding their heads up and opening their mouths. When an earthquake happened somewhere, Du Zhu fell to that side and touched the teether, causing the dragon in the direction of the earthquake to spit out copper beads, fell into the mouth of the copper toad, and made a "dangling" sound, and people knew which direction the earthquake occurred.

Jiri Drum Cart

The car used to calculate road mileage in ancient China was developed from a "track car". The car is divided into two upper and lower floors. The upper floor is equipped with a bell and the lower floor is equipped with a drum. The car has a wooden man wearing an e-crown and wearing a robe. The car will drum once after walking ten miles. Hit the drum ten times and you will ring the bell once to calculate the distance traveled. The Drum Drum Cart is a vehicle that records travel automatically. It is an automatic mechanical object developed by scientists and inventors in ancient Chinese society. It is called an ancient Chinese robot by robot experts.

Wooden cow stray horse

The transportation vehicles invented by Zhuge Liang, the prime minister of Shu Han in the Three Kingdoms period, were divided into wooden cattle and stray horses. Each foot of the Mu Ni Liuma has a small wheel that can be steered to enable it to drive faster on flat ground and maintain good stability on rugged mountain roads. The transport vehicles of the Three Kingdoms period were driven by two wheels, the big wheels were responsible for driving, and the four small wheels were responsible for supporting and assisting movement.

Three Eyed Owl

A short firearm in ancient China, cast from iron or crude steel. The shape is a joint of three bamboo joints, each with a small hole on the outside. Add gunpowder in the stern tube during use, and finally fill steel balls or cast iron blocks, crushed iron sand, etc., and add a fire cap at the small hole. When in use, strike the fire cap at the launching platform such as stone, detonate the gunpowder and launch the projectile. The stern tubes can be fired in turns. A handle seat is left at the tail of the three-eyed salamander, and wooden rods of different lengths are installed for holding to ensure the safety of the shooter.

Bingjian

A container used to hold ice in ancient summer days, juxtaposed with food. There are lifting rings on both sides of the ice box, with a cover on the top, and a double money hole on the top, which is both a hand and a cold air outlet. This is done by placing the ice cubes in a wooden or bronze box. The function is clear, which can not only save food, but also emit cold air, which makes the room cool. It's just that ice doesn't exist at all times of the year, especially in the hot summer, ice is very precious.

Do you think that these ancient black technologies are very attractive? In fact, there were many very powerful weapons in ancient times, and now many technologies are not comparable to these technologies. Many of us have to say that the ancients were really very powerful! Editor / Zhao Yongjing
