The concept of bearings has been around for a long time in ancient China. However, due to the limited processing capacity, there is a huge difference between ancient bearings and modern bearings. In modern times, it is commonly called ball bearings, and in the past, it seemed that it could only be called bearings. Due to the limitations of materials and processes, ancient vehicles could not have too much load, otherwise the friction coefficient was too large, and the car would not be able to move.

In order to carry out the Great Industrial Leap Forward, the 'revolutionary army' not only needs a large number of power machinery, but also needs good transmission devices. Transmission requires a huge amount of bearings, gears and screws. Zhao Ze, who is engaged in machinery, has spent a lot of effort to make a breakthrough in this regard.

In the beginning, the machine factory only worked on hardwood bearings. However, Shi Stone, who was in charge of metallurgy, was soon forced to classify the products of the iron and steel plant and select some of the better quality for deep processing, and the emergence of metal bearings was very natural.

Nowadays, the products within the 'Revolutionary Army' are also equipped with different bearings according to the different use environments. For example, wheelbarrows used in complex terrain are also being manufactured in large quantities, but they do not have high bearing requirements, so they simply continue to use hardwood bearings. Artillery, carriages with higher bearing requirements switched to metal bearings. Ship power has the highest requirements for transmission, so the best quality metal bearings are selected.

Metal bearings lubricated with animal fats and fats have a very low coefficient of friction and a high enough load-bearing capacity. When they began to be mass-produced, the number of wagons in the 'revolutionary army' began to rise. As a result, the horses pulling the carts have become so tight that the donkey carts and ox carts have run out.

But it's always good to have a car. After Zhou Qingfeng occupied Tianjin, he devoted himself to running the big city, and he built a lot of new houses and roads in the city, and renovated the former 'car and ship shops' personnel, so it was natural to ask for the construction of the city's public transportation. The first hundred horse-drawn buses showed up.

Due to the lack of horses, the animals pulling the carts did not care much. The horse-drawn bus can sit in a lap for only five cents, and the first day of investment caused a sensation in the city. The common people are also very strange, and they are willing to make a carriage to go around the city and feel the novelty.

Passenger carriages stretch the territory, and a car can seat up to 20 people, and two horses pull it, and the speed is two or three times faster than a person walking. The benefits of this bus system are immediately familiar – they can travel much longer distances at the same time. This may seem simple, but it is not easy to achieve, and its impact is even more profound.

In the past, farmers outside the city wanted to pick vegetables to sell in the city, but they really got up early and couldn't transport much in the dark. Now it's much simpler, farmers can spend a little money and put their goods on the trailer behind the bus. This transportation volume is larger, saving time, and even because of the large purchase of the 'revolutionary army', it is easy to sell.

The development of transportation can pool idle social resources at a lower cost. At the same time, it also makes the transmission of information smoother, and in turn strengthens the monitoring and management of the 'revolutionary army' at the bottom of society. That's a great thing.

The people in Tianjin are amazed by the emergence of this public transport system, and feel the benefits of this leapfrog development from various angles. Only Sun Yuanhua had a big question mark in his heart after experiencing this bus and carriage once-he was originally going to go out of the city to visit the new agricultural machinery in the collective farm outside the city, but he was fascinated by a carriage halfway through.

"This car has twenty people, and there is a tow bucket for goods hanging in the back of the car, how can it be pulled so easily?"

"The axles of this car are very strange, very different from normal axles. The two horses pulled without froze, too strange and too strange. ”

"It's so easy to pull twenty people, wouldn't it be the same if you pull soldiers on the battlefield? The newspaper said that the first batch of 100 carriages was put into operation, wouldn't it be easy to pull 2,000 men and horses to rush quickly? How good is that? The land of Gyeonggi is flat and the roads are crisscrossed. The 'revolutionary army' can fight wherever it wants, and it is impossible to defend against it on the battlefield. ”

The more Sun Yuanhua thought about it, the more he couldn't help sweating, and immediately became interested in this way of bearing. He was sneaky, sneaky, looking left and right, and going straight around the carriage. Seeing that he was always dangling in front of him, the groom asked loudly, "Sir, do you want to get in the car?" Five cents a person. We are from the Drum Tower to Xinguang Farm, 17 stations along the way, to ensure that you sit comfortably. ”

Sun Yuanhua came out of the city, but in order to experience the power of this bearing again, he actually took out another five cents to take the car back. He writhed and shrivelled in his seat, unable to survive for a moment. Others were talking and laughing in the car, chattering about the convenience of this bus and horse-drawn carriage.

"Hey, it's not all bad. I've been sitting for a long time, and my butt hurts. ”

"I can run more than 20 miles in half an hour, what is it if my butt hurts? It's a lot faster than walking. ”

"In the past, I went out of the city to visit a relative, and I went out early in the morning, so I could get there before dark. I took this carriage a few days ago and made another trip, and I arrived at noon. When my relatives saw me, they all said, "Why did I come so early?" I'll just say that there aren't many places that Dashuai has to do by 'bus', otherwise I would have been able to go to my relatives' house for breakfast. ”

The cheapness and convenience of transportation can greatly promote the circulation of people and materials, and the laughter and laughter in the carriage is the joy of the people at the bottom of the car. After returning to the city, Sun Yuanhua was in no mood to talk to the strong servants who accompanied him. He got off the train again and watched the crowds at the newly opened Gulou Station, standing still.

In the past, leaving home was a very risky affair, and the 'car and ship' transportation was in the hands of a small number of gang forces, and even the porters who transported the goods were not good people. It is a lucky thing to go out and reach the destination safely, if you just lose a package and property on the way, it is a small matter, and the loss of human life is a big thing.

Now that Zhou Qingfeng occupies Tianjin, he is the first to pay attention to public order, and there is zero tolerance for idle people and gang members. Director Marco Shima is even more sensitive, fierce as a wolf, cleaning up the three religions and nine streams all day long - Ma Gonggong wants a reputation, even if it is the reputation of a cool official. As long as he can record history, he will be happy. Not to mention that he is rarely in power, and he has been praised by the people.

In the past few days, the newspapers have repeatedly praised the good people and good deeds of the Tianjin Police Department, and praised Director Ma. Because he handled cases strictly, enforced the law fairly, and swept away a large amount of social dregs, a few days ago a common man actually sent him a pennant.

This is a goddamn unprecedented!

Ma Gonggong couldn't believe it when he saw the 'iron-faced selfless' pennant, and he was extremely surprised. He tossed and turned excitedly that night and couldn't sleep, laughing all night. The pennant was covered by him like a quilt on his chest, and his heart was beyond words.

The improvement of social order has rejuvenated the lives of ordinary people, and people are more willing to communicate and work hard, and at the same time have a strong sense of attachment and security to the regime of the 'revolutionary army' - for example, the Guards strictly inculcate the concept of 'people's army' in their training, and they are all dispatched to carry out voluntary labor every once in a while, and take the initiative to help citizens solve their problems.

In the past, officers and soldiers were a combination of gangsters and second-rate gangsters and bandits and bullies, and the common people fled when they saw it and hid when they heard it. However, Zhou Qingfeng's bad habits of the old army were to crack down severely, first of all, to set up a military police to picket the army and military discipline.

The Guards were expanded to accommodate many Ming soldiers and junior officers, who were often taught repeatedly. Zhou Qingfeng waited for these guys to make mistakes, and after being arrested, they were quickly tried and executed, and they apologized to the people in the newspapers, constantly building momentum - it was through this attitude of not evading, covering up, and not covering up that he won over the people's hearts.

Zhou Qingfeng is not afraid of problems at all, and even wishes that there would be problems. If something goes wrong, he can have an excuse to solve it.

Sun Yuanhua didn't understand Zhou Qingfeng's scheme, he only stood at the door of the station, and when he saw the bustling flow of people coming in and out, he always felt unreal. Under normal circumstances, only the temple fair held during the Chinese New Year has such a flow of people.

But even at the temple fair, there are often all kinds of 'shooting flowers' abducting children, drugging and abducting women, and selling strong pills to cheat. But there is no such thing at this station - the armored infantry is here.

In the past, only the government and military camps were garrisoned, but now soldiers of the 'revolutionary army' can often be seen in Tianjin. This is an effective way to maintain law and order in situations where the police are inadequate. From spitting and cutting in line, to fighting and brawling, these things will be punished. The common people who came and went were more in awe than fear of these upright soldiers, but they did not reject them.

For Sun Yuanhua from the Ming Court, he really couldn't figure out how this was done? He saw the flow of people carried by the carriage from the bearing of a carriage, the local security from the large number of people, and then the people's hearts from the local security, and by the way, he saw the guards standing in the military posture at the entrance and exit of the station.

"Master, it's not too early, do you still go outside the city to see the new agricultural machinery?" The strong servant who followed asked.

"Sir, I'm not in the mood to go out of the city today." Sun Yuanhua stood still.

The strong servant followed Sun Yuanhua's gaze and saw that his master had been staring at the soldiers opposite. He reminded: "Master, what's so nice about this anti-thief soldier? If you're feeling bad, why not find a place to take a break or two, or find a teahouse to listen to a book. Last time, which one said that "Romance of the Sui and Tang Dynasties" was really good. ”

Listening to his servant still thinking about "Romance of the Sui and Tang Dynasties", Sun Yuanhua couldn't help but smile bitterly. He replied unquestioned, "How long have those soldiers on the other side been standing?" ”

Ah......, the strong servant didn't understand the meaning of this question, "We went out of the city to take the car, and those people stood somewhere." When we get back by car, where are they still there? It's been at least an hour, and they've been dumbfounded, like fools. ”

Seeing the servant's hippie smiling face, Sun Yuanhua turned his head and asked, "Do you really think they are stupid?" My master is training in Tongzhou, and I wish my subordinates were such fools. However, the soldiers he recruited were all too smart, so that they were all crooked in the school line, and they shouted impatiently for half an hour. But the soldiers of the 'revolutionary army' on the other side stood for at least an hour, not moving at all. ”

The servant hurriedly restrained his smile and said along with his master's words: "Yes, yes, the master's eyes are like torches." This is an anti-thief and strong soldier, who can endure hardships and obey orders. It is said that 'the mountain is easy, and the Yue family is difficult', and such a rock-like team will definitely be able to fight. But just standing so stupidly, I will too. As long as I give more money and have enough to eat, I can stand for a day. Why bother with this, sir? ”

Why bother?

Sun Yuanhua lowered his head and sighed, and said listlessly: "I wrote to Shizun in the past few days to tell me about what I saw in Tianjin, and Shizun also wrote back to mention his training in Tongzhou. The anti-thieves blocked the key places in Tianjin, and the government and the opposition were shaken, and they sought a way to self-improvement.

But my Ming soldiers still can't eat, dress, and get money. There are so many rats in the DPRK and the Central People's Republic of China, how many ...... are there, why didn't the 'revolutionary army' kill a few more people in the previous attack on the capital?! ”
