The first rebel of the Tang Dynasty

The key is on the pole?Why is the solution to traffic on the pole?Is there something magical about it?It looks very ordinary, except for some lights, there seems to be nothing special about it? !

Li Shimin was even more incomprehensible.

And finally asked: "Tell me, what is the use of this pole?"

The two were overjoyed.

As long as Li Shimin wants to know, then they have a way to persuade him.

I was afraid that Li Shimin would not give them this chance.

So Duan Lun first said: "Master Huang, listen to me!"

"Tell me, I'm listening!" Li Shimin must be thinking whether to ink or not!hurry up!
"Do you think this sand table is different?" He asked suddenly!

Li Shimin became a little impatient.

"Isn't this just an ordinary sand table? Some people have cars and buildings! There are also some poles with lights!"

In Li Shimin's view, this is the sand table he saw before. Some people have cars and buildings.

It's just that the people and cars inside are relatively large.

It's a little different from the sand table I used.

"It's an ordinary sand table!" Dai Zhou said.

Then he said: "But there are some wire rod-like things on this sand table. Did Mr. Huang see that they are lighting up in an orderly manner?"

"Yes! I did see it!" Li Shimin said.

But these red and green things in front of him made him feel strange.

What is that and why is it here.

Could it be that Li Yin is messing around again?
Duan Lun followed Dai Zhou's words:
"Look at the light on the pole, it is called a motor vehicle signal light, and the one under the pole is called a pedestrian crosswalk signal light. The two lights face different objects. The motor vehicle signal light is for cars, while the other is for people to see. Yes. They are the opposite. When the car is going, people have to stop, but when people are going, the car cannot go. There are also some lines on the ground, called sidewalk lines, where people can only walk. When someone walks, the car must give way..."

The two introduced you one by one, and there is a lot of knowledge output at this time!
Li Shimin seemed to understand but half understood.

"and then?"

He seemed to understand, but he didn't seem to understand.

then……

Then isn't it obvious?

The two were a little anxious.

Don't you understand?
As soon as Li Yin said it, they understood it!
I thought that Li Shimin would understand here, but they were wrong.

It seems that you have to talk about it!
Dai Zhou also said: "Then, when this signal light is used in traffic, it will play an extremely important decisive role in the smooth flow of traffic in the future. It avoids congestion and increases the passing rate in advance! That is to say, with it, the traffic in the future will be smooth and orderly!"

Li Shimin is just like everyone else.

In this regard, it is still somewhat difficult to understand.

Combined with the sand table demonstration, he seemed to understand something.

But it's just too convoluted.

After all, it was the first time I came into contact with this thing.

So he said: "This method sounds good! Does everyone have to tell them that? If so, the cost of education will not be low! When meeting some people who have not studied, they will be even more puzzled! "

Li Shimin saw something different.Everyone sees things differently because the heights are different.

As far as cars are concerned, there are few cars. As far as people are concerned, there are millions of people in Chang'an City, plus the entire Tang Dynasty, the population is extremely large.

If everyone has to teach them, it will be difficult.

Therefore, he said the same thing.

Duan Lun said: "Mr. summed it up into six words! Very easy to remember!"

"Which six words?" Li Shimin was puzzled, is there such a thing?

Dai Zhou and Duan Lun said in unison, "Stop at the red light! Go at the green light!"

"Ah? How to solve it?" This induction made him completely confused!
"Whether it's a person or a car, you must stop when you see a red light. Because the two signal lights are opposite! A red light for a car, a green light for a sidewalk, and vice versa...The lights they see are different. Come on, you can also turn the rules into nursery rhymes to enhance people's cognition..."

"I saw it, and it is indeed so."

Li Shimin watched the demonstration on the sand table carefully, and it was indeed so.

When they heard him say that, the two were overjoyed.

In this way, Li Shimin agreed.

However, Li Shimin's frown deepened.

"This thing is really useful! It can indeed make the whole traffic orderly. But what if someone doesn't obey it?"

Li Shimin thought the same as the two of them.

Yes, if someone does not abide by it, what should we do?

The two got the answer from Li Yin.

Then he said: "Master Huang, don't worry, Mr. Huang has already mentioned the method."

"Say!"

Duan Lun said: "This involves the power of the court. The court must have people. Special people to manage."

"That's right, because even if Shengtang Group wants to control it, they can't control it. After all, they are not law enforcement officers, and everything has to be done by the court!" Duan Lun said.

"That's true." Li Shimin agreed.

"Mr. also said!"

"say what?"

"It is said that the manager can be given a name, and this name can be heard by the people. They have the power to enforce the law and also have the power to fine."

"Name? Enforcement and fines?"

Li Shimin was also confused.

At the same time, I was a little surprised and a little unhappy.

Why do you say that.

Because of the surprise, Li Yin arranged the next management method for himself.

What is not happy is how Li Yin arranges his next management method.

"Yes!"

Duan Lun said.

"Then what are they?" Li Shimin asked again.

"Mr. thought that the name of this manager could be a traffic controller, simply called a traffic controller! They have the power to enforce the law and can fine, and there are rules for fines..."

Upon hearing this, Li Shimin interrupted Duan Lun's words.

"The traffic controller is too ugly, let's call it a traffic controller!"

This guy still has his own ideas, he can't completely listen to Li Yin.

Especially in the name, he can be independent.

Why do you have to listen to Li Yin?
Therefore, he changed a word.

Change staff to guard.

It feels more relevant.

In this regard, Li Yin didn't want to care too much about it.

Let him do whatever he wants.

He just provides some methods and makes some money.

If this information light is sold, it will be another huge purchase.

As time goes by, the demand is also huge.

There will be a large number of intersections in the future, and if these intersections want to be smooth, they need these lights.

"Yes!"

Duan Lun responded.

He and Dai Zhou knew that Li Shimin was still a little cautious.

"Okay, let's talk about the fines next."

Regarding the fine, he wanted to know what Li Yin would do.

In fact, Li Yin has not particularly refined.

Because the traffic at the beginning is also considered simple.
