"It's okay not to wear it, the sun is still quite big today!But you still have to wear a few more clothes, this turtleneck sweater must be worn that, you don't feel cold, it's because the air conditioning is turned on at home, so it doesn't feel cold, in fact, the temperature outside is very low, if you don't wear it well, you will definitely be frozen into a popsicle when you go out!"

Lin Quan took her turtleneck sweater, this dress was bought online, I don't know if it fits the size, the things they want to buy when they go out today include clothes, shoes and other things, of course, there are others!

"What a hassle!"

Gu Xirou rolled her eyes, she couldn't do anything about him, she didn't understand, how could a man do it to the point that a woman couldn't do it!

On their side, if a man is so gentle, it will be considered abnormal, and it is not good to be sympathetic to his wife, but it is not good to do too much.

However, although Gu Xirou rolled her eyes, she still obediently put on the dress that Lin Quan brought over, speaking of which, after all, the other party is for her good, and she cares about her, and she can't refuse the other party's kindness!

"Alright! Let's go!"

Lin Quanzai carefully checked her equipment, and after making sure that there was no problem, he took her out the door.

Because it's winter, there should be fewer people on the street, but today's weather is better, the sun is very big, and the air doesn't look as bad as a few days ago, before the air pollution in the north was sealed and blown to the south, they were also affected, the control index for several days has exceeded 200, this is moderate pollution, belongs to the kind of situation that can't go out, outdoor activities should be reduced, otherwise it is easy to inhale too much toxic pollution gas.

Today's sky still looks very blue, probably because the cold air has formed a stable pressure band!

After the air pressure stabilized, the wind gradually stopped, and the polluted air from the north was not blown over!

There is no pedestrian street near his house to visit, there are stores here, but there are not many, so Lin Quan took Gu Xirou to take the subway to the pedestrian street of Jiefang Road to see, there are several pedestrian streets on the Jiangnan side, but the one that is closer to his house is the one on the side of the Conservatory, and it only takes a few stops to get there by subway, and it is still very close.

"What is this?"

Gu Xirou looked down with some curiosity, this thing will move by itself, and people will be moved by it after standing on it, and it seems to lead to the underground, which makes her a little curious, and she doesn't understand what this thing is.

"This one, this one is called an elevator!"

Lin Quan smiled, walked to the edge of the elevator, and motioned for her to go up.

"Elevator?"

Gu Xirou tried to stand up for a moment, and then immediately jumped back, because she found that this thing would actually run with her, which made her feel that her center of gravity was unstable and she was about to fall, so she jumped back in fright, looking vigilant, full of suspicion about this thing, and didn't believe it at all.

"Hehe, it's okay, it's safe, just stand firm!"

Lin Quan stood up, and then stretched out his hand to her, because the elevator was going down, she was stunned for a moment, and didn't hand it over, so Lin Quan was taken away, he hurriedly took a step back, and continued to stretch out his hand: "It's okay, it's safe, trust me!"

Fortunately, the flow of people in this subway station is not large, so there are not many people around them waiting to pass, so no one urges them, otherwise there will be a bunch of people blocked behind Kendi at this time.

Gu Xirou hesitated, but still stretched out her hand, grabbed Lin Quan's hand tightly, and was pulled up by Lin Quan.

"Hold on to this thing, it's okay!"

Lin Quan showed her, Gu Xirou followed his example and grabbed the handrail on the side, and sure enough, she felt that the previous feeling of shaking her center of gravity was gone.

And after standing on it for a moment, she felt like she had regained her balance.

"Actually, as long as you don't get so nervous and relax your body, although this thing is always reported, but according to the frequency of its use, this thing is still very safe!"

"yes, I see!"

Gu Xirou nodded and began to observe this thing, obviously she was somewhat interested in this thing.

"Is this thing called an elevator?"

Gu Xirou seemed to have thought of something and asked.

"Well, it's called an elevator!"

"Is it powered by something called electricity?"

She seemed to figure out something, and at this point she became interested in how this thing worked.

"yes, you can see it before I even tell it, yes, it's very smart!"

Lin Quan smiled and praised her.

Gu Xirou glanced at him, snorted, and said: "I saw that the Wang family's electric light would turn on, and I heard them say that it is powered by something called electricity, so when I heard you say that the elevator, I also thought about whether this thing is also driven by electricity!"

Now it was Lin Quan's turn to be surprised, it turned out to be like this!

"This shows that your observation and thinking and reasoning skills are good!"

Lin Quan smiled and walked to the ticket office.

If you take the subway, you can usually swipe the card, which can be handled by yourself, or you can buy a one-time electromagnetic ticket at the ticket vending machine.

However, considering that she will use it in the future, Lin Quan gave her a bus card, which used to be only able to take the bus, but with the development of the city's means of transportation, there are other channels and business expansion, and this thing can now do a lot more.

Take the bus, take the subway, pay the utility bill, charge the phone bill, and even use it for shopping at some designated locations!

Lin Quan had an idea in his heart, if it weren't for the rapid popularization of Alipay and WeChat payment, the two convenient mobile payment methods, maybe this kind of bus card payment method might have become popular in the entire Jiangcheng and become the mainstream!

There are great business opportunities here, but unfortunately, they have not yet been completely developed, and they have been completely defeated by competitors who are bigger than them!

I have to say that this is still a little regrettable, after all, although Jiangcheng is a big city with 10 million people, there are not many large enterprises that can handle it.

"Take this card, swipe it, this door will open by itself, and then come quickly, you can enter the subway station and take the train!"

Lin Quandi swiped the card, and the door opened.

Then he motioned for Gu Xirou to try it too.

"Like this?"

Gu Xirou swiped the card, but she didn't come in time, and the door closed again.

"Uh, you can't brush it anymore, or you can turn it over......"

Lin Quan touched his head, he didn't expect such a situation to happen, and he had a slight headache.

"Oh, it's not hard!"

Gu Xirou showed her skills and flew over directly, and several people around were stunned and looked at them dumbfounded.
