What was the situation of the air conditioned express train 2000 years ago, the treasure that scramb

The air-conditioned express train before 2000 was called a treasure because of its fast speed and comfortable ride and became a weapon in the military, transportation, and disaster relief. First of all, the military aspect, since the construction of the railway, has been an important part of the war. If there had been air-conditioned express trains 2,000 years ago, soldiers would not have had to march day and night, making them tired and hurried.

Since ancient times, the soldiers have been fast, imagine that the original soldiers rushed to a battlefield, need to walk day and night for a few days or even more than ten days, and need to recuperate to the destination to recover the physical strength and energy consumed, with the air-conditioned express train, you can shorten the long travel time to more than ten hours or even a few hours, and the soldiers blow the air conditioner, complete the task of rest in the car, get off the car to the designated battlefield and enter the battle, in the face of the enemy army because of the long travel time and low morale of the troops, Then this high-morale and energetic unit on the express train can easily be defeated. There is an old saying in terms of grain and grass, before the soldiers and horses move, the grain and grass go first. With the express train, the soldiers and horses can move together, and if the grain and grass run out, it won't be long before the express train can transport it again.

In terms of transportation, ancient people generally used horse-drawn carriages or horseback riding, etc., and it took several days or even months to reach distant places, and it was inconvenient to travel so that many people who traveled did not return to their hometowns again since they left their hometowns to work hard for their futures. With air-conditioned express trains, travel takes only a few hours, and with air-conditioning, you don't have to feel uncomfortable because of the hot or cold weather, making it a pleasure to travel or visit family. There are more benefits than the old way such as horse-drawn carriages, and people will compete to ride, which will greatly affect the country's economic development and enhance the country's comprehensive national strength.

In the event of a disaster in one place, air-conditioned express trains can continuously transport people and materials from all over the country to the affected area, support the affected area, and help the construction of the area

In this way, the air-conditioned express train of 2000 years ago is really a treasure.

It was 2000, which is equivalent to 20 years ago, when the air-conditioned express one he had air-conditioned and the second was the express, which was of course a treasure in everyone's eyes, and the rarity was like the current first-class cabin.

Because 2000 years ago, the air-conditioned express car should be regarded as a product of relatively developed technology, and in many countries, the air-conditioned express car was not available at that time, so many countries regarded this as a treasure at that time.

It has to be! At that time, air-conditioned express trains were only available at a higher price in the hands of scalpers to buy tickets. It's fast and doesn't smell like stinky feet, and it's much more beautiful than the environment and speed of a green car.

The copper chariot and horse was invented in the Qin Dynasty more than 2000 years ago, unearthed in the bronze cultural relics on the west side of the Mausoleum of the First Qin Emperor, the unearthed two copper chariots and horses are responsible for opening the road, one is the royal royal, the royal royal of course belongs to the soft sleeper air-conditioned car, first of all, starting from the soft sleeper, the inside of the copper chariot and horse is covered with exquisite soft cushions, magnificent, this soft cushion is called Wenyin in the history books, the person who sits on the copper wooden horse can both lie down and sit, it is not comfortable to sit inside, but ordinary people can not enjoy the soft sleeper of the royal family.

So the soft sleeper can be had, in ancient times when science and technology were not developed, what about the air conditioner? As early as 2000 years ago, the ancients had mastered the double-layer sliding technology, and made many tiny holes in the window panel of the copper wooden horse, which was convenient for ventilation and not cold.
