The first rebel of the Tang Dynasty

while they drank their tea.

Li Yin stood up.

He steps aside.

Then he said, "Come here!"

He motioned for the two to go over.

So, the two stood up suspiciously, and walked carefully to Li Yin's side.

It turned out that there was a sand table in front of Li Yin.

They seemed to have seen this sand table when they came in.

But I didn't particularly care.

When the two looked at the sand table carefully, they found that it was a miniature sample of the surroundings of the library.

They were fascinated.

Because this miniature is just like the real thing.

People feel shocked.

Duan Lun first asked, "Sir, what is this?"

He didn't understand why Li Yin wanted them to watch this.

And Li Yin said:

"It's the solution."

The simple five words made the two of them overjoyed.

However, there is no way to see the solution.

It seems unreasonable to see the solution just by looking at the model.

The two only knew that the road inside was somewhat different from that in the library.

Because in their view, there seems to be some more lights here.

Some weird lighting.

There are two kinds of lights, red and green.

As a result, the two of them were even more puzzled.

Until Li Yin went on to introduce:

"Maybe you will be wondering, but it's normal for you to be wondering, because what I'm going to do next is a major event that will change the traffic in the entire Tang Dynasty. It's also because the number of cars will increase."

Although I don't know what Li Yin is talking about.

But the two still listened carefully.

Li Yin knew that the two of them didn't understand the meaning.

Then he went somewhere, and there was a red button there.

I saw him press it down.

The car on the sand table actually moved.

It was almost as if it were real.

Duan Lun and Dai Zhou were dumbfounded.

The combination of the lights and the car is simply wonderful.

There are not only cars, but also some villains who are squeezed into a fist.

These people actually followed suit.

It was wonderful, simply wonderful.

If Li Shimin was here at this time, he might be too shocked.

However, if they rely on these things alone, it seems that they are just making trouble. Before Li Yin explained how to solve the problem, they still didn't understand the mystery of it.

Just when the two were dazzled.

Li Yin asked: "How is it? What do you think?"

The two said they didn't see anything, they just saw the cars coming and going, and they didn't feel anything special.

Dai Zhou said: "I don't see anything, sir expressly!"

"Yes, sir, what did you do this for?" Duan Lun asked.

"Just to tell you, you must not understand, so with this sand table, let you feel the situation on the spot."

The two still don't quite understand.

Li Yin said again: "This thing I made is called a traffic signal light, or it can also be called a traffic light!"

"traffic light?"

The two were shocked, what was that?
"Yes, have you seen the intersection in front of the library? There are four sets of traffic lights there!"

Following Li Yin's finger, there are really four sets of lights, one red and one green.

Why four groups are mentioned, because the lights above the pole also have lights under the pole.They are red and green light bulbs.

"I see!"

Dai Zhou said.

"Okay, you see the light on the pole is called a motor vehicle signal light, and the one under the pole is called a pedestrian crossing signal light. You can understand it this way. One signal light is for cars and the other is for people. They are On the contrary, when the car is going, people have to stop, and when people are going, the car cannot go. And I also drew some lines for people, which are called sidewalks, and people can only walk here.”

Li Yin introduced.

The two still seem to understand.

"You can see that there is no interaction between the traffic flow and people. Let me tell you a few points, and you will understand."

Li Yin said very patiently.

Then he added:

The rules of motor vehicle signal lights are as follows: when the green light is on, vehicles are allowed to pass, but turning vehicles must not obstruct the passing of straight vehicles and pedestrians.

When the red light is on, vehicles are prohibited from passing.

pedestrian crossing lights
The rules are as follows:

When the green light is on, pedestrians are allowed to cross the crosswalk.

When the red light is on, pedestrians are prohibited from entering the crosswalk, but those who have already entered the crosswalk may continue to pass or wait at the centerline of the road.

……

"So, 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!"

Li Yin said so.

But the two still don't understand.

"The method is good, but it is a bit difficult to understand!"

Duan Lun said.

"Just remember six words, stop at a red light and go at a green light!" Li Yin said.

The two suddenly realized.

Dai Zhou said again: "This idea is good, but what if someone doesn't follow it? This signal light is equivalent to nothing!"

Duan Lun also realized this.

He said: "Yes, this still depends on self-awareness. If people don't realize it, then everything will be in vain, which means that there is no change."

Regarding these matters, Li Yin had already had an idea.

He said: "The Shengtang Group alone will not be able to do this thing, and the court must come out to preside over it! Otherwise, everything will be in vain!"

When the two heard it, it turned out to be the case.

Ganqing Li Yin is waiting for the two to come to ask questions.

If so, that would be really interesting.

If that's the case, then people will also know why Li Yin made preparations in advance.

Now that there is a way, it depends on what the court does.

But what will the court do?
The two still have no bottom.

Duan Lun then asked: "Then what do we want the court to do?"

"If you are the enforcers of the rules! I say that, do you understand?"

Rule enforcer?
Li Yin knew that the two of them didn't understand the meaning.

Then he said: "I will provide you with the rules, but you have to implement them. If you encounter someone who does not follow the rules, you can fine them. The role of these fines is to deter some people from committing crimes again. My suggestion is to Motor vehicles are fined [-] renminbi each time! Pedestrians are fined [-] renminbi each time. Those who commit repeated offenses can make it public, because the fine has no effect on them.

As for the role of fines, the first is to educate people, and the second is to give revenue to the court!It can also make the traffic flow smoothly, so three birds with one stone are all real benefits. "

When Li Yin said that, both of them were so surprised that their jaws almost dropped.

It could be so.

Then, next, they will go to Li Shimin and talk about everything Li Yin said.

The two also stared at the sand table.

Then, next, they may want this sandbox for other purposes.
