"No need to pay for the old class, let them pay for themselves."

Anyway, there are few people at all.

So, taking advantage of this opportunity, Lu Shaochuan came to the two automatic sales machines, so that the people in the class were arranged into two teams, and they paid the tickets with their mobile phones.

Then, he watched the subway route and asked Li Guoping: "Old class, which one should we get off at the car?"

Li Guoping looked at them with a smile, and pointed directly at one of the sites and said: "Science and technology museum, our goal is the military science and technology museum."

Military Science and Technology Museum?

Lu Shaochuan looked at him unknown, and didn't understand what Li Guoping went to do.

But he did not question. After he showed everyone how to buy tickets, he asked them to buy them by themselves.

The students who bought the ticket for the first time seemed a little excited. A two of them seemed to be Liu Ye who had not seen the world, and looked at the subway one -time coin at one time and touched it.

After security inspection, after the coin, they came to the bottom and waited for the subway.

During the period, Lu Shaochuan heard many people discuss the subway.

He knew their feelings very well, and he was also surprised when Su Shuangjiang took him on the subway.

After all, I never took the subway before.

At this moment, Li Guoping suddenly said: "The first subway in my country was opened to traffic in the capital on the day of the National Day in 1969."

Students who were still stunned immediately closed their mouths, and quietly listened to the class teacher about the past history.

At the same time, other passers-by who stood with them were a little surprised to see "Saint Leah's students are so well-behaved.

In their impression, "Students of Saint Leah, a noble school, should be arrogant, indifferent, arrogant and arrogant.

But now they see a group of well -behaved chicken, and they are still a group of handsome and beautiful chicks.

"It's just that the first subway was not open to the public, because the idea of ​​the construction of the subway was used for combat reserve."

Li Guoping continued to tell them the history of the subway. It happened that a subway came over. They walked into the compartment and continued to listen.

The customers who were sitting quietly in the carriage couldn't help but stunned when they saw so many students coming in.

"Why do you have so many students? This point shouldn't you? Is this a collective skins?"

Hearing that someone said Gu Yun, turned around, and saw a aunt in his forties watched in doubt.

"No." She looked at the aunt, showing a smile of the exam, and explained: "It is our class teacher who takes us out to stroll around!"

Gu Yun was very delicate and beautiful. After laughing, he was like a pity of a loving little rabbit. He could see the aunt's heart soft.

When she was about to ask, she saw a middle -aged and elderly man surrounded by the students.

"Until January 15, 1971, the first phase of the capital subway project began trial operation. At that time, it was only received to visit the masses."

Li Guoping smiled and talked about the world's first subway: "The first one is in 1863. I can remember what important things happened in that era."

In the 1960s, it had something to do with the subway. Is it?

"The Industrial Revolution! Da Ying's industrial revolution lasted from the 1960s to the beginning of the 19th century." The first one was Lu Shaochuan.

This knowledge is not difficult, what is difficult is that Lu Shaochuan actually remembers!

Lu Shaochuan's mouth twitched slightly. There was no way. As the only liberal arts student in the tuition class, Ke Yu, who said in his ear every day, it was difficult to remember it!

"Hey, right, at that time in the era of steam. In order to solve the problem of traffic, there was a subway."

From the subway to the industrial revolution, the industrial revolution talks about the world system of capitalism, and then the socialist system of breeding the flowers, and then it talks about a series of developments in the country after the founding of the People's Republic of China.

Speaking of the site of the Science and Technology Museum, when the students got off the bus, the other passengers in the compartment were a little unhappy.

The students followed Li Guoping, bought the ticket obediently, and then went in.

This is the Military Science and Technology Museum, and the exhibitions are all various military weapons.

This is also the first time that this group of students came here. Looking at the exhibited weapons and research processes, they couldn't help but snoring twice.

"Come here, look here."

Li Guoping pointed to one of the things and beckoned to his students: "Come and come."

The students leaned over and found that what Li Guoping was pointing at was the Tianshu researched by Su Shuangjiang.

"Wow! Su Ge's Tianshu!" This group of students was instantly excited. If there were no glass around, they would probably rush up.

"I discovered last time, the Science and Technology Museum actually updated the Tianshu of the frost."

After Su Shuangjiang has researched the entire Beidou series, the Science and Technology Museum will probably display all of them.

Lu Shaochuan watched this seemingly known machine dog. This was only modified by the military, but it was generally similar to the original Tianshu.

He took out his mobile phone and took a photo and sent it to the other party.

Lu Shaochuan originally thought that Su Shuangjiang would not reply to him until five or six o'clock, but not long after the photo was sent, he received a reply from the other party: [? Where have you been?]

[Are you not in class?] Lu Shaochuan was more surprised than him.

[Rest, where have you been?] Su Shuangjiang looked at the time, shouldn't he be in Chinese class at this point?

Then, a video call popped up, Su Shuangjiang was slightly taken aback, then walked to the corner and clicked on the video.

As soon as the camera opened, Su Shuangjiang saw a bunch of people excitedly saying hello to him: "Brother Su!!!"

Su Shuangjiang looked at the classmates in the video and was full of doubts: "Where are you going?"
