The World of Yellow Sky

At this time, cheers of "Wan Sheng" filled his ears, and Yan Zhong looked in the direction of Jingxing Pass.

He had never seen the scene of the emperor going on tour, but Yan Zhong felt that even if the real emperor traveled, he might not be as loved as Xu An.

"Obtain the world and have the Tao, and get the people, and then the world can be achieved. If the people have the Tao, they will have their hearts, and they will gain the people. Once the people have the Tao, they can gather with them if they want, and don't do what they hate."

Yan Zhong withdrew his gaze and looked at the Yellow Turban Army guarding the people on both sides of the official road. Just today, he finally understood the meaning of this passage.

The aspiration of the people is the trend of the world.

"Entry."

A smile finally appeared on Xu An's face. He raised the whip in his hand and swung it forward. At the same time, his legs gently pressed the horse's belly. The bay red horse under the seat shook its head slightly and trotted forward with four hooves. and go.

The armored cavalry of the Xiaoqi Battalion behind them also accelerated their horse speed together.

Under Xu An's command, the last batch of transferred people also began to march towards Jingxing Pass, but they were not the last team to enter Jingxing Pass this year.

Xu Huang also stationed in Puwu with two armies, and Lu Bu also took Yi Cong to wander around the original stronghold of the Han army outside Jingxing Pass.

With the troops of Xu Huang and Lu Bu present, the rangers of the Han army would have absolutely no way of threatening the people who were transferring. They were the last team to enter Jingxing Pass.

Xu An did not enter the gate first, but stopped at the position before closing the gate together with Yan Zhong and others.

The endless flow of people slowly flowed into the tall pass. Jingxing Pass, which had been vacant for a while, became busy again because of the arrival of more than [-] people.

Xu An looked at the crowd walking slowly forward, but slowly frowned.

His frown made Yan Zhong feel a little puzzled, and now the biggest problem has been solved.

All the people in the four prefectures are about to enter Jingxing Pass and enter Bingzhou, why Xu An suddenly frowned at this time made Yan Zhong very puzzled.

Yan Zhong asked: "If Mr. Ming has any doubts, you might as well say it out, and think about it in your heart alone. I'm afraid it will take several times more energy to solve it."

"I'm just a little surprised, how come this way, why are the carriages on two wheels?"

Xu An raised his horsewhip and pointed at a marching baggage train on the official road.

The supply team was obviously the people's supply team, and most of the Bingzhou Army's supply team was equipped with wheelbarrows and many carriages.

As for this baggage team, many people used poles and other things to carry food and grass, and the carriages that carried the baggage they saw were basically manpower.

"Two wheels? Carriages always have two wheels?"

Yan Zhong glanced at Xu An suspiciously, he didn't know why Xu An asked such a question suddenly.

Xu An looked at the transport team that was entering the city, and thought about it in his mind.

In terms of logistics, except for the wheelbarrow that Xu An had proposed before, he did not manage it anymore.

All the logistics management of the Yellow Turban Army is basically under the control of Yan Zhong, and Xu An is mainly responsible for combat training. This time, seeing the supply team, some doubts arose.

Xu An thought about all the carriages he had seen, only to realize that all the carriages he had seen seemed to have two wheels, they could only pull not much cargo, and they were very bumpy.

During Guangzong's breakout battle in the past, the frame used to transport Zhang Jiao's coffin was considered tall, but it also had two wheels, and it was extremely bumpy to stand on.

Later, Xu An got out of the car and fought on foot. The guards on the frame carrying Zhang Jiao's coffin followed Zhang Liang and killed Guangzong.

Thinking back carefully, Xu An had seen some old photos of the Qing Dynasty on the Internet, as well as some graphic and video materials. It seemed that all the carriages had two wheels.

Not only folk carriages, but also some military chariots with two wheels. Qi Jiguang's chariot camp Xu An has some impressions. Now that I think about it, the chariots used in the chariot camp also have two wheels.

Xu An turned his head to look at Yan Zhong, and asked: "Is there no four-wheeled carriage? Isn't the four-wheeled carriage able to transport more goods, and it is a little smoother, and more convenient?"

The four-wheeled carriage should be more spacious, comfortable and stable than the two-wheeled carriage, but Xu An was a little surprised.

"Four rounds?" Hearing Xu An's question, it was Yan Zhong who was puzzled now.

"There are four-wheeled vehicles."

Yan Zhong thought about it carefully, and then he opened his mouth and said, Xu An's sudden question made Yan Zhong really puzzled, because this is a common sense question, Xu An should not be ignorant.

Xu An cheered up when he heard Yan Zhong mentioning the four-wheeled carriage.

"I have seen a four-wheeled carriage once in the area of ​​Jizhou, but the four-wheeled carriage is not as good as Minggong said. The steering of the four-wheeled carriage is a big problem. If you want to steer, you can only rely on the strength of the cattle and horses pulling the cart. In this way, several oxen and horses are needed, but it is not as convenient as directly dividing them into several carts to transport goods."

Listening to Yan Zhong's narration, Xu An also frowned, the steering of the four-wheeler is not a problem at all.

"How difficult is it to steer a four-wheeled vehicle? Isn't that an easy task?"

In American western movies, there are often horse-drawn four-wheeled carriages, tarpaulin-covered freight carriages, and people-carrying carriages. There are many types, and steering is not a problem at all.

Compared with four-wheeled carriages, the disadvantages of two-wheeled carriages are very obvious.

The center of gravity of a two-wheeled carriage is located at the shaft, and the shaft resting on the waist of the horse will greatly increase the burden on the horse, making the horse prone to fatigue and unable to pull the cart with all its strength.

The second is that if the ride is very bumpy, the passengers will feel very uncomfortable.

The carriages of two-wheeled carriages are often inclined, and the people and goods in the carriage are always inclined.

The back of the horse is always in a state of ups and downs when it is traveling. It is still the end of the Eastern Han Dynasty, but there are no rubber tires, and there is no shock absorption system for the carriage. When the carriage is driving, the carriage can be said to be very bumpy.

This is also one of the reasons why in ancient China, although there were carriages, sedan chairs appeared.

Secondly, the supporting equipment is cumbersome.

It is impossible for a two-wheeled carriage to stop as soon as the horses pulling the cart stop like a four-wheeled carriage.

Whenever the carriage is stopped, something must be placed in front to carry the shaft, so that the pulling horses can rest and the two-wheeled carriage can stop steadily.

"and many more……"

Yan Zhong was a little surprised, but when he was about to continue talking, Xu An suddenly thought of something.

There were indeed four-wheeled carriages in ancient China. He remembered that in the "Picture of Exiting Police and Entrance", it seems that Emperor Wanli of Ming Shenzong rode in a four-wheeled carriage.

It was a four-wheeled cart pulled by more than 20 white horses. It seemed that there was no wheel steering system, but wheels were installed around the carriage.

If the four wheels are simply installed on a frame, the only way to turn the wheel is to twist it by brute force, which is very laborious. Naturally, a lot of animals are needed to pull it, which is laborious.

Fixed four wheels, so that the car can only walk slowly in a straight line, turn slowly, and turn too fast will cause the car to roll over

And in this era, there are strict requirements on the number of horse-drawn carts, and the crime of overstepping is not a small crime.

Xu An pondered for a while and asked: "That is to say, if the steering problem is solved and a large number of carriages are installed, it should be able to improve the logistics transportation capacity of our army."

Xu An rubbed his temple with his left hand, and tried hard to recall.

"If Minggong can really solve the problem that the four-wheeled carriage cannot turn, then logically speaking, it should be able to improve the logistics capabilities of our army." Yan Zhong thought for a while, nodded, and then continued: "But there are still many problems Needs to be addressed."

"One thing I think of now is that although the four-wheeled carriage can transport more goods, it means that the requirements for official roads are also higher, and Ming Gong should also know more about the situation of the state's official roads."

"Military division, wait a moment, let me think carefully."

At this time, Xu An discovered something that he had been ignoring before.

He glanced at the reins in his hand, then turned to look at Xu Da who was beside him.

"Where is the military pawn's baggage team?"

Xu Da recalled it for a while, and immediately said: "It shouldn't be far away. About two miles behind the people's luggage team is the luggage team of our military soldiers."

"follow me."

Without hesitation, Xu An waved his horsewhip and drove directly to the rear of the queue.

Although Yan Zhong and the others didn't know why, seeing Xu An taking a step ahead, they could only follow behind Xu An and rush towards the back of the crowd.

Xu An drove all the way with his personal guards, and soon arrived at the side of the military pawns and luggage team.

He thought of some things, but he was a little confused all of a sudden. He needed to see the real thing to confirm his thoughts.

The configuration of the armed forces' supply team is obviously much better than that of the people's supply team, and it is also much neater.

On both sides are guard soldiers, in the center are heavy soldiers pushing wheelbarrows, and there are many carriages.

Of course, none of these carriages are two-wheeled carriages.

Xu An didn't waste any time, he notified the military officer of the supply team, and asked a soldier driving his carriage to drive his carriage out.

"Meet the great virtuous teacher!"

The soldier stopped the carriage, then shouted excitedly, and knelt down on the ground.

"In my way of peace, there is no kneeling salute, just meet with military salute."

Xu An stepped down from the horse, saw the soldier kneeling down, stepped forward a little faster, and helped the soldier who was kneeling on the ground.

"It's not a big deal. I suddenly thought of something and wanted to verify it. Just wait a while."

Xu An patted the excited soldier on the shoulder, then walked up to the carriage and looked at it carefully.

He pulled the harness on the horse, then looked around the carriage.

At this time, there was another rush of horseshoes, and Yan Zhong and his party had already arrived nearby.

Seeing Xu An frowning and observing the pulling horse, Yan Zhong's heart moved slightly. Such a situation proved that Xu An must have discovered something.

The last time I saw Xu An's expression like this was when I was making a plan to take over the Yellow Turban Army from the Four States, when I was discussing that Zhending and other cities were solid and difficult to break through, Xu An went to check the trebuchet.

Yan Zhong still remembers that after Xu An inspected the catapult, he only took a few days to draw the blueprint of the new-style catapult, that is, the one that shined in Puwu City and Zhending City, and was called "Thunderbolt" by the Han court. cart" catapult.

The so-called strong cities of Zhending and Xiaquyang were as weak as tofu under the attack of Xu Anding's new catapult called "counterweight catapult".

Chapter 457 Saddle-type tying method, four-wheeled carriage

Xu An held the harness of the cart and horse, closed his eyes, and recalled carefully.

He remembered one thing, that is, how to tie a horse is actually a very important thing.

It seems that it is just how the tether is tied to the horse's body, just like a man pulls a cart with a belt, and a tracker pulls a boat with a rope.

But in fact, the driving method is very important. The correct driving method can maximize the use of the pulling force of the horse, and can also protect the horse.

Although ancient Europe was a little ahead in this respect because it solved the steering problem of the four-wheeled carriage, it increased the load capacity of the carriage.

However, Westerners at that time were very backward and unscientific in how to drive horses, and even strangled the horses.

The earliest method of driving a Western ancient car was simply to fix the livestock on the scale with a neck strap.

When the livestock drags the vehicle forward, it pulls the neck strap. The neck of the livestock is the main stress-bearing part, so this driving method is called "neck strap driving method".

This driving method is neither scientific nor advanced, and has some very obvious defects.

Take a draft horse as an example, since the neck strap is directly tied to the neck of the draft horse, and the draft horse pulls the vehicle, the neck strap directly presses the draft horse's trachea.

The airway for breathing is compressed, which also makes it difficult for the horse to breathe during galloping, which not only affects the running speed and strength of the horse, but more seriously, it can even lead to the death of the horse.

Cars in Mesopotamia used only the neckband, which was slightly more advanced in the days of ancient Greece and the Roman Republic, but it was also extremely limited.

It’s just that in addition to the neck strap, a belly strap is added, but the horse must be tightly tied to the scale when driving in this way, and the neck strap will still compress the horse’s trachea, resulting in the death of the draft horse.

However, the "yoke-type driving method" adopted by China has avoided the occurrence of such problems.

It is precisely because of the backwardness of the driving method that most of the ancient Western chariots were long-distance, and there were no chariots that could fight at close range or attack as in the Spring and Autumn and Warring States Periods of China.

There are three types of tying methods for horses: the yoke type, the chest strap type, and the saddle type.

The terracotta warriors and horses in the Mausoleum of Emperor Qinshihuang in Xi'an are very famous. There is a picture that I believe many people are familiar with. It is a bronze chariot pulled by four horses.

The bronze chariots and horses unearthed from the Mausoleum of Qin Shihuang adopt the exact yoke style, and the yoke placed on the shoulders of the horse bears force.

The first emperor died, the world was in chaos, and Qin was destroyed.

Qin lost its deer, and the whole world pursued it. In the end, Liu Bang ruled the world and established the Han Dynasty.

The Chinese car system has also begun to undergo changes, and the pre-Qin-style yoke-style driving method has been replaced by a new system.

That is to say, the chest belt riding method. The appearance of the chest belt lowers the load-bearing part of the horse to the chest, and the yoke becomes a simple fulcrum, which only plays the role of supporting the balance and the shaft.

The carriage drawn on the hollow bricks of the Han Dynasty in my country adopts the chest belt type, and the chest and armor are stressed, and the carriage has changed from the original single shaft to the double shaft.

However, the method of driving horse-drawn carriages began to stagnate at this time and did not continue to develop.

There is evidence that the era lasts until the Yuan Dynasty, which is about the end of the thirteenth century, more than 1200 AD.

On the figurines of the chariot unearthed at that time, the saddle-style driving method appeared.

The saddle-style riding method is more advanced and scientific than the chest-strap style, and the main force is on the shoulders and back of the horse.

Xu An tugged on the belt on the carriage, and it turned out to be the chest belt style of driving. At this time in the last years of the Eastern Han Dynasty, the chest belt style of driving had already been popularized.

The saddle-style driving method just happened to be known to Xu An. Although he had never seen a four-wheeled carriage up close in real life, he also knew how to fasten the saddle-style driving method.

But in later generations, there are quite a lot of computer games, and one of them happened to be a game based on the western United States, called Wilderness or something, and it was very particular about reality.

The vehicle inside is a four-wheeled carriage, so Xu An is quite clear about the saddle-style driving method and the general structure of the four-wheeled carriage, but there are many details that need to be recalled.
