The sun is still hanging high in the west sky, and there are not many pedestrians on the road, which is completely different from the crowded scene when I came in the evening. This is a workshop area, which is very different from the bustling area of ​​the capital with a large number of idle people.

Everyone got off the oil-walled cart and looked around, and they were all surprised.

"Hey, aren't Song Zijing and others there? Why did they get here too?"

Zeng Gongliang pointed at a few people not far away and turned around and said to everyone.

Xu Ping looked at it and said, "It should be invited by Wang Junjun. If you don't see him, he will be there."

Wang Gongchen stayed in the museum for a long time and had a good relationship with these people. This time he returned to Beijing to report his work, of course he had to call everyone over to gather. It was boring to live in the capital, and gathering every few days was the biggest pastime.

The people there also saw Xu Ping and his party, hurriedly walked over and greeted Xu Ping one by one.

After reconciling the ceremony, Xu Ping asked Wang Gongchen: "The weather is hot now, what are you doing there?"

Wang Gongchen smiled embarrassedly: "There is a carriage from the new business, and we are watching there. Because it is different from the passenger carriage I saw in the city, we are talking about it."

"That is a carriage that carries goods, of course, different from a carriage that carries passengers. The business has gradually started shipping goods. How can we transport things without a carriage? Besides, this carriage is made and sold to the public, which is also a revenue and can facilitate the people to carry goods."

Wang Gongchen said: "It is because we know it is a cart that we are talking about it. You see, except for the oil-walled carts we usually come here to ride, the flat carts used on the market are also four-wheeled. Why does this new cart have only two wheels? Compared with a cart with four wheels, don't the two wheels be less cart?"

After hearing this, Xu Ping said angrily: "The amount of goods is used to take depends on the size of the cart. What does it have to do with how many wheels?"

Wang Gongchen shook his head repeatedly: "But we still can't understand why the carriage transporting carriage does not use four wheels like the carriage carrying passengers. It doesn't seem a bit shabby if two wheels are missing?"

Xu Ping looked at the few people standing there just now, all of whom were confused, and his heart moved, and said to everyone: "It is natural that the carriage for transporting goods has changed from four wheels to two wheels. This is true. If anyone can explain this truth clearly, I will have a reward today, and I will give it a reward!"

Wang Gongchen was stunned: "Why? This is not a business, why do you still have to give a reward?"

"Because I see that none of you can explain the truth. When you read and write articles, you can speak in a slight manner, from the Three Sovereigns and Five Emperors to the Sui and Tang Dynasties, you can speak tens of thousands of words at will. But you know nothing about these things. The sages often talk about worldly knowledge, which is nothing more than physics and life. This is physics and a kind of knowledge. We are officials, we emphasize nature, life and knowledge, and correct our minds and cultivate ourselves so that we will not fall into evil ways. We must also talk about physics and understand the principles of all things in the world, so that we can handle political affairs with ease and avoid being confused and blind. You are in the Pavilion and the time to learn worldly principles, and today we will take the test."

Wang Gongchen laughed and said, "I don't know what the deputy envoy wants to reward us. It's too light and I'm afraid no one will take care of it."

Xu Ping smiled slightly: "Then how do you think you will get the reward? What about the new four-wheeled carriage that the venue is launched?"

As soon as Xu Ping finished speaking, everyone around him took a breath. This heavy reward was really too heavy. The new car should be at least two taels of jin. The decoration is a little more luxurious, and more than one thousand taels of jin is nothing.

"Do you take this seriously?" Zeng Gongliang looked at Xu Ping and asked carefully.

Xu Ping looked at him and smiled: "Did you see that I said something I didn't take seriously?"

The rewards that Xu Ping drove were too heavy. Everyone was stunned for a while before they realized that Xu Ping was not joking. Although they knew that Xu Ping would definitely rely on him, they would still gather next to the carriages.

These cars were manufactured by the business today and were pulled out to the road for test drive. When the people who came here for test drive went to the tea shop next to drink tea, the car stopped on the side of the road.

The four-wheeled carriage is light and flexible, and it is stable and not bumpy when driving. It is very suitable for people to ride, but these characteristics are obviously different from the requirements for cargo transportation. Even if the two-wheeled carriage is on a flat road, it is still constantly up and down. It is actually inappropriate to carry passengers, especially for elderly people and women, who would rather ride in a ox cart.

However, although the two-wheeled carriage is furious, it is conducive to heavy loads, can fully exert horsepower, and is also suitable for long-distance transportation.

The reason is this, but if you can analyze and understand it clearly, Xu Ping believes that no one of these people can do it.

In fact, I have not really used these two vehicles. I have actually used these two vehicles to transport goods. Many people are afraid that they have questions about the fact that two-wheeled vehicles are more efficient than four-wheeled vehicles. If you want to analyze and understand clearly, you really need some professional knowledge.

Xu Ping wanted to take this opportunity to let these talented scholars understand that it is useless to read the books of sages alone. In fact, Confucius himself never shamelessly asked questions when encountering things he didn't understand, but his disciples took up the airs of scholars.

Following everyone, Xu Ping stood by two parked carriages silently.

One of the two cars had already unloaded the horse and tied it to the willow tree on the side of the road to drink water, while the other horse was still on the car.

After walking around the car, Ouyang Xiu spoke first, and came to Xu Ping, and bowed: "To be done, in a certain way, there is nothing mysterious about the two wheels of this car, but because the donkey and horse carriages used in the past were like this. The craftsmen of the Sansi carriage made this way according to the old conventions."

Xu Ping looked at Ouyang Xiu without saying anything until he felt guilty, and then said, "I have to look at everything in the Sansi New Market Service before selling it. I agreed to this car with the craftsmen, but you said it was just based on the previous folk customs. Do you think I am stupid or are you stupid?"

After hearing Ouyang Xiu's words, Xu Ping almost spat at him. I paid a reward of hundreds of cents of coins. Do you think you are playing brain teasers with you? It's so easy, I just threw the money on the ground and heard it sound!

Seeing that Xu Ping was rude, Ouyang Xiu couldn't help but blush, but he didn't dare to do anything. His library and pavilion proofreading was too far away from Xu Ping's Longtu Pavilion waiting system, and his answer was indeed disrespectful to Xu Ping.

He stood there with embarrassment for a while, Ouyang Xiu bowed to Xu Ping: "It's Xiaguan Menglang!"

After saying that, he turned around and returned to the car, looked left and right, and felt a sense of enthusiasm in his heart. He found out the truth that Xu Ping said and let out a good breath. Everything in the world looks like a thousand ways, but the truth is still simple. What's the problem?

(I can't finish the code today, so I'll post it with tomorrow's update. I'm sorry.)
