There are not many people in the subway, they are in groups of three or three.

It takes about half an hour to get from Jinke Station to Changshou Station, the closest to Gaoang's residence, but less than an hour.

WeChat cannot log in to Metropolis, you can only use Alipay, and you have to turn on Bluetooth.

"It's really troublesome."

After muttering, Gao Ang finally got everything done and scanned the displayed QR code to the gate.

Just when he was about to enter the station, he was stopped by a voice.

"Sir, please show your ID card."

Looking back, it turned out to be the police uncle on duty.

"Are you calling me?" Gao Ang asked uncertainly, pointing to his nose.

"Yes, this is my document, please cooperate with our inspection."

The police uncle performed the required inspection steps in an orderly manner, so that Gao Ang could not find any fault.

He was very polite, and he was a handsome guy. There was a heroic female policewoman next to him. Gao Ang could only take out his ID card honestly.

"Well, is there any problem?"

When talking, Gao Ang was a little cautious and a little confused.

"It's okay," the policeman looked at Gao's face with his ID card for a long time, and looked at him repeatedly and repeatedly, and then returned the ID card to him and asked him to leave, "It's just a routine check."

After taking the ID card, Gao Ang touched his nose, looking puzzled.

When he walked away, he heard the conversation between the two.

"It's very normal, your eyes are too bad, right?" the man's voice.

"What's your name?" the woman's voice.

"I didn't pay attention. It seems that my surname is Gao, but you can't say that this kid is quite handsome, but he has a bald man, so if you don't check who he wants..."

OK, Gao Ang knows why he was verified. It turns out that it is because of his bald head.

Not only the People's Guards wanted to investigate him, but even other passengers in the subway kept a distance from him intentionally or unintentionally.

After touching his bald head, Gao Ang felt a little embarrassed.

He doesn't want to be bald either. He also likes to have long hair. It looks so good to have a hairstyle and dye it in a color.

But I was struck by lightning, what can I do?

Fortunately, the hair has begun to grow, and when you rub the scalp, you can feel a little scratching feeling.

The weather is better today, so he didn't wear a hat when he went out.

The main feeling is that the sun shines on the scalp is so comfortable.

Maybe if you look at the sun more often, your hair will grow faster?

While thinking about it, the subway door closed and then slowly opened.

There are not many passengers in the carriage, so it would be nice to have two or three people in a row of seats.

Sitting in the seat steadily, Douyu live broadcast was played on the mobile phone, Gao Qiang seemed very enjoyable.

He hasn't taken the subway to transport for a long time.

Even if you have to go out, most of them drive by yourself, and if you really can’t do it, you will take a taxi.

"Next stop: Changshou Station, please..."

Hearing the mechanical girl’s message to the station, Gao Ang stood up from his seat.

The train is still running smoothly, and there will be no swaying left and right when walking in the car.

"Crunch"

Suddenly, a harsh friction sound came, followed by a huge force coming from the soles of the feet. The high body fell directly to the side due to inertia.

This time, it is not slow brake after entering the station, but emergency braking.

According to high estimates, the subway's operating speed should be about 40 kilometers per hour, which is about 11.1 meters per second.

Without any reminder or support, it is impossible for an individual to stabilize his body.

He could already predict his embarrassment: a bald man who was almost two meters tall, lowered his head and played with his cell phone, and then slammed it into the bottom of the train with a "bang".

Just when his body was tilted extremely and was about to fall, Gao Hang tried his best to stretch out his left arm, hoping to find something to support it or pull it so that his fall posture would not be too embarrassing.

In desperation, he also tried his best to hope that his feet could stand more steadily, and unconsciously clamped his toes a lot.

As a result, nothing was caught, but something seemed to be stuck on the soles of the feet.

Under the inertial force, the high still tilted sideward at a large angle uncontrollably.

However, except for his feet, no other parts of his body touched the bottom of the car.

He was like a big tree, firmly grasping the bottom of the car with his roots.

All this happened in an instant, and the subway stopped completely after a few seconds.

Then came the radio voice of the conductor, which meant that passengers got off the train in an orderly manner and followed the station staff to evacuate from the emergency passage in an orderly manner.

Although there were not many passengers in the car, such a sudden accident still caused a lot of panic to everyone.

The girl opposite Gao Ang’s lips were almost bitten, her face turned pale and her head was sweating.

Her trembling lips and shaking hands all showed how much fear she had endured.

"It's okay, get out of the car quickly."

Out of machismo, Gao Ang still comforted him softly.

The main reason is that this girl looks pretty good, and she must score at least 83 points if she scores, which is very outstanding.

"Well...well, get off, get off..."

Seeing that she could walk by herself, Gao Ann didn't help her in one go. If she was misunderstood and acted like a hooligan, it would be hard to explain.

Gao Qiang, who was following the girl, did not notice that the girl's cell phone was in the camera state.

Following the station staff, everyone finally arrived at the nearest station.

No need to ask, Gao An knew that there must be a track lying incident ahead.

He had already learned about this matter almost completely from the smell of blood in the circulating air and the mixed discussions.

The deceased is a male, with unknown reasons for lying on the track and unknown identity.

Relevant departments have also arrived, including ambulances, but they are basically not available.

After this incident happened, Gao Ang was no longer interested in transferring to other subways and left the subway station directly from this station.

As for why a man is unable to think about suicide, the reason is nothing more than money or people.

He is not a person who likes gossip, especially for this kind of tragedy. The specific reason will be announced in a few days.

While sitting in the taxi, Gao Ang was thinking about another question.

How did he stand firm on the emergency braking train just now?

He was sure that he didn't support anything, and there was no 502 glue or something like that in the soles of his feet.

But he just stood firm, and the lower plate could be said to be motionless, just like nailing it there.

It is a bit wrong to say that "nail" is there, it should be said that "sucking" is there.

That's right, it's just "sucking", like sucking iron, and it's sucking hard on the bottom of the car.

This kind of kung fu is given a name in martial arts novels or films and TV dramas: Qianjinzhu.

It means that the body is as heavy as a thousand pounds, and can be firmly stabilized on the ground. Even if you push or kick him, you cannot move him at all.

But things like Qianjin Pendant can be explained scientifically.

When he was in college, Gao Ang had the honor to see a military training instructor performing this skill.

He stood alone on the playground, asking the three classmates to push him hard from one direction.

After he performed his merits, the three of them tried their best to take care of themselves, but they had no choice but to do anything to him.

Of course, in the end, he cracked the instructor's magical skills high.

He asked three students to use a trick to pull onions onions on dry land, and directly pulled the instructor out of the ground, and carried it around the playground. As a result, the four of them stood together for two hours in military posture.

The scene in my memory told him that the so-called Thousand-pound pendant is just an inappropriate angle of force, and of course this has something to do with the magnitude of force.

For example, if an object is placed on a horizontal plane and the vertical force is used, it will definitely not cause the object to move horizontally.

As the direction of the force changes and the magnitude of the force changes, it is possible that the object will be displaced.

Of course, the magnitude of this angle and the magnitude of force must be taken into account the friction coefficient between the object and the ground.

When the magnitude of the force remains unchanged, it changes with the direction of the force until the object can be displaced. At this time, the angle formed between the direction of the force and the horizontal plane is called the friction angle.

In other words, as long as the magnitude of the force remains unchanged, the angle between the direction of the force and the ground is smaller than the friction angle, the object will be displaced.
