Mohist organ art, explained in the present language, is the technology of mechanical manufacturing. We all know that Mozi is a very pragmatic person with high attainments in military and physics. Through his own knowledge of physics, he built many defensive weapons, most of which were built on the city walls, so he came up with the idea of organ city.
There are three kinds of Yugoslav capital weapons mentioned in Mozi. The first type is a crossbow car, which is placed on the wall and operated by ten people. It can shoot dozens or hundreds of crossbows at a time. The tail end of the arrow is tied with a rope, which is connected to the wheel, so that the shot arrow can be quickly recovered and the use efficiency of the crossbow can be improved.
The second is the turning gun, which is a bit like the anti-aircraft gun in the last decade. It is also placed on the wall, and the range is longer than the crossbow. It is operated by two people, one is responsible for shooting and the other is responsible for adjusting the direction, so the operation is more flexible. The third is a domestic car, which is similar to a slingshot, but belongs to the Yugoslav capital weapon. It can resist the enemy's siege troops by throwing charcoal fire.
Mohist organs are just some Yugoslav capital weapons using physical and mechanical knowledge. In our modern eyes, these devices are very simple machines. But at that time, from the level of productivity, it was already a very high technology, and it was very powerful at that time. This phenomenon is like our inner feelings when we mention laser weapons and nuclear weapons-this is probably the ultimate of weapons, so we will write these weapons in horror. Thousands of years later, people may think that we are very powerful now, but if they know what we are talking about, they will only hehe.
