I put you in charge of the child, and you raised a monster!

After leaving the old street of Jingdezhen, the convoy drove towards the outskirts of the city.

Outside the car window, the wet road surface had been half-dried by the sun.

Yesterday, the sachets from the pharmacy were still hanging on the children's bags, their faint scent of mugwort mingling with the aroma of breakfast in the car.

Zhao Lei was noticeably quieter today.

It's not that he doesn't want to talk.

It's because of the "discipline" Shen Ling'er has been doing all these days that it's become a conditioned reflex.

Whenever they arrived at a new place, they would first observe Shen Ling'er's expression.

He didn't dare to start a tune if Shen Ling'er didn't speak.

Bai Sisi couldn't help but laugh at his demeanor: "Why are you so composed today?"

Zhao Lei said in a serious tone: "I am now a mature trainee in the Career Experience Season."

Shen Ling'er sat next to Yang Mi, holding a small piece of rice cake in her hand, and looked up at him.

"Mature learners don't constantly emphasize their maturity."

Zhao Lei: "..."

Bai Sisi laughed so hard her shoulders twitched.

"After driving for ten minutes, I still couldn't hold on."

Holding her water bottle, Chen Doudou earnestly asked the director, "Is there any food for this job today?"

The director, already used to it, simply nodded: "Yes."

Chen Doudou was instantly relieved.

"Then I can experience it seriously."

Lin Jia sighed, "Are you willing to take any job as long as you can make a living?"

Chen Doudou thought for a moment: "No, not exactly."

Chen Hao asked curiously, "What other conditions are there?"

Chen Doudou said earnestly, "There can't be too little rice."

Everyone: "..."

Shen Ling'er nodded: "This condition is simple, but it's very realistic."

Zhao Lei couldn't help but laugh out loud.

The director cleared his throat and finally announced today's schedule.

"Today we're going to the High-Speed ​​Rail Dispatch and Maintenance Experience Center."

"In the morning, we visited the station's dispatching system and simulated train crew and security check procedures."

"I'm going to the high-speed train maintenance depot this afternoon to observe the daily maintenance of the trains."

The car suddenly became lively.

Zhao Mengmeng's eyes lit up: "Is it a very, very fast train?"

Bai Sisi nodded with a smile: "Yes, it's the high-speed rail."

Zhou Xiaoyu asked softly, "Why can it run so fast?"

Zhao Lei immediately perked up and almost slapped his thigh.

"I know that!"

He had just opened his mouth when he suddenly saw Shen Ling'er raise her eyes, so he lowered his voice again.

"High-speed trains run fast because their tracks, power systems, air resistance systems, and scheduling systems are all very advanced."

Shen Ling'er glanced at him.

"This time it started off well."

Zhao Lei's eyes lit up immediately.

"Did you hear that! I had a good start to the day!"

Shen Ling'er added, "But now you're not doing well again."

Zhao Lei: "..."

The comments section was already buzzing with laughter.

"Hahaha, Zhao Lei's mature training has been broken!"

"High-speed rail experience! This is a novel job."

"Could Ling'er spot the problem just by looking at the train?"

"She can even spot a malfunction in the wind vane; the experienced high-speed rail driver is under pressure."

"DouDou's core career experience: Food is essential."

The convoy soon arrived at the high-speed rail experience center.

This place is very big.

There is a simulated platform at the entrance, with a high-speed train carriage for display parked next to it.

In the distance, you can see the silver-white roof of the maintenance depot, with tracks extending out in neat rows, as if measured by a ruler.

They were greeted by a middle-aged railway engineer surnamed Luo.

Engineer Luo was wearing a dark blue work uniform and spoke very steadily.

Welcome everyone.

"Today we will mainly learn how high-speed trains operate safely."

"When people take a bus, they only think that it is fast, punctual, and comfortable."

"But there are many positions working together behind the scenes."

"Dispatch, drivers, crew, maintenance, security checks—every step must be handled properly."

Upon hearing the words "Don't panic," Zhao Lei immediately looked at Shen Ling'er.

Shen Ling'er was looking up at the traffic lights in the distance.

She didn't reply, but just looked at it intently for a while.

Engineer Luo asked with a smile, "Little friend, what are you looking at?"

Shen Ling'er pointed to the signal lights and ground markings next to the track.

"Everything here is arranged very clearly."

"Red, yellow, and green are not just for people to see, but also to let people know at a glance whether it can move now."

"The markings along the track are also very neat, which shows that the people here usually do things according to their positions."

"With high-speed rail being so fast, the worst thing isn't that it's a little slow, but that some people think it's okay to be a little short."

Engineer Luo was taken aback.

Immediately, the smile on his face became more serious.

"That's absolutely right."

"In railway safety, the worst thing is to be 'good enough'."

"When things are almost over, that's often the beginning of an accident."

Zhao Lei slowly turned to the camera and lowered his voice.

"Dear viewers, this is Teacher Ling'er's first lesson on the high-speed rail experience."

"The railway is most afraid of being too similar."

Shen Ling'er nodded.

"This sentence is acceptable."

Zhao Lei immediately straightened up.

Bai Sisi quickly reminded him, "Don't shout."

Zhao Lei silently sat back down and whispered, "I know, I have a deep voice."

The comments section was flooded with messages.

"They're here! Ling'er immediately checked the signals and markings."

"The railway's biggest fear is being 'almost the same'; that's a really harsh statement."

"Inspector Luo's expression is starting to get serious."

"Zhao Lei is happier than winning the lottery to receive a simple 'yes'."

Engineer Luo first led everyone to the simulation dispatch room.

A large screen displays the circuit diagram.

There are many small dots of light on the screen, and each dot has a train number next to it.

They move slowly along the line, like a quiet yet complex game of chess.

Zhao Mengmeng stared wide-eyed.

"So many little trains."

Zhou Xiaoyu whispered, "Won't they bump into each other?"

Engineer Luo explained with a smile, "No. Each train has its own operating area and schedule."

"The dispatcher needs to monitor the entire line."

"We need to know which vehicle is where, which route is empty, and which section requires a speed limit."

Chen Doudou asked seriously, "Then how will they eat?"

Lin Jia closed her eyes.

"Chen Doudou, they talked about the car first."

Engineer Luo laughed: "Dispatchers also need to eat, but their posts can't be vacant; there will be rotations."

Shen Ling'er nodded: "This arrangement is correct."

Chen Doudou immediately felt relieved: "Then they won't be starving while hauling the cars."

Zhao Lei almost burst out laughing.

Looking at the big screen, Shen Ling'er suddenly said, "This is a bit like football."

Zhao Lei was taken aback: "How does it resemble me?"

Shen Ling'er pointed to the running line on the screen.

"Each vehicle runs on its own line."

"If the car in front is slowing down, the cars behind can't force their way on."

"Either wait, or make adjustments."

"If you only look at one car, you might not think it's a big deal if it's two minutes late."

"But there are cars behind it, cars next to it, and it also takes up space at the entrance."

"If one place falls into chaos, the rest will follow suit."

Engineer Luo's eyes lit up immediately.

"Your understanding is very accurate."

"Railway dispatching is all about the system, not just a single train."

Zhao Lei was completely stunned.

"Teacher Ling'er, is this your first time looking at a scheduling chart?"

Shen Ling'er nodded.

"first."

Zhao Lei: "Then how did you understand it so quickly?"

Shen Ling'er looked at him and said, "Because it's already drawn very clearly in the picture."

"Lines, points, time, and direction are all there."

"Don't just watch the show; first observe who is waiting for whom and who is being blocked by whom, and you'll understand something."

Zhao Lei: "..."

Bai Sisi laughed and said, "You've been taught a lesson again."

The barrage of comments instantly became dense.

"She mistook the scheduling diagram for a football formation!"

"Who is waiting for whom, and who is being blocked by whom, the explanation is all too clear."

"This kid's view of the system is truly terrifying."

"Engineer Luo has completely started treating her as a serious student."

Suddenly, a small notification appeared on the simulation screen.

The train's stop at the next station was extended by two minutes.

Engineer Luo smiled and said, "Now let's simulate a small scenario."

"The train ahead has an extended stop time, which will affect subsequent trains."

"What do you all think we should do?"

Zhao Lei immediately raised his hand: "Should we ask the cars behind us to slow down?"

Engineer Luo nodded: "That's one way."

Shen Ling'er looked at the screen but didn't speak immediately.

She spoke after a few seconds.

"We can't just let the first car behind us go slow."

Engineer Luo's brow furrowed: "Why?"

Shen Ling'er spoke very completely.

"Because if the first car is slow, the second car will catch up."

"If we only focus on the nearest bus, then buses behind will crowd into the crowd one after another."

"We should first check how many cars are behind this section of the line, and then check if there are any gaps that can be adjusted in advance."

"If a vehicle hasn't departed yet, we can delay its departure."

"This way, the pressure won't all pile up in the middle."

The simulation room fell silent for a moment.

Engineer Luo looked at the young dispatcher next to him.

The young dispatcher also looked somewhat surprised.

Engineer Luo smiled.

"right."

"This is a very important point in scheduling."

"Problems cannot be dealt with only where they occur; we must look forward and also backward."

Zhao Lei took a slow breath.

"Teacher Ling'er, this doesn't seem like you're here for an experience anymore."

Shen Ling'er looked at him: "I'm just following the instructions in the diagram."

Zhao Lei: "..."

The live chat exploded.

"Holy crap, she really understood delayed transmission?"

"We can't just focus on the nearest vehicle; that will only create more pressure on subsequent vehicles. Isn't that what system scheduling is all about?"

"A five-year-old child can look at a high-speed rail timetable and immediately come up with a scheduling strategy."

"Luo Gong's smile has become an expression of approval."

After leaving the control room, the production crew entered the simulated platform.

There are realistic ticket gates, waiting areas, yellow lines on the platform, and train doors.

Mr. Luo said, "Next, I'll experience being a train attendant and a platform staff member."

"The most important thing in platform work is maintaining order."

"Do not cross the yellow line, do not rush on or off the train, and do not force your way in when the doors are closing."

Zhao Mengmeng nodded obediently: "I won't squeeze."

Zhou Xiaoyu whispered, "I don't know either."

Chen Doudou asked seriously, "What if the food is in the car?"

Lin Jia grabbed him and said, "You can't squeeze in even if the food is in the car."

Shen Ling'er nodded: "The food can wait until the next stop, but people can't be stuck in the door."

Chen Doudou instantly became serious.

"Then I'll wait."

Zhao Lei couldn't stop laughing.

Engineer Luo led everyone through the experience of platform guidance.

Zhao Lei put on the vest for the experience, held the sign, and immediately got into the swing of things.

"Passengers, please line up to board the train!"

Shen Ling'er stood to the side and glanced at him.

"Your voice is fine on the platform, but your movements are problematic."

Zhao Lei was stunned: "What did I do wrong?"

Shen Ling'er pointed to the sign in his hand.

"You're asking for too little."

"People behind you can't see, but they can hear you talking, so they'll push forward to see."

"The sign needs to be held up so that it can be seen even from behind the crowd."

"Your position shouldn't block the car door."

"If you stand here now, tourists will walk around you."

"As soon as people circle around, the group falls apart."

Engineer Luo nodded repeatedly as he listened.

"Yes, platform guidance isn't just about shouting."

"Positioning, gestures, and eye contact are all very important."

Zhao Lei silently raised the sign a little higher, then took half a step back to the side.

"How about this?"

Shen Ling'er took a look.

"Much better."

Zhao Lei instantly perked up: "Did I do a good job guiding the crowd?"

Shen Ling'er thought for a moment.

"Let's not cause any more trouble for now."

Zhao Lei: "..."

Bai Sisi laughed so hard she bent over.

"This is already a very high rating, don't be picky."

The comments section was filled with laughter.

"Let's not cause any more trouble for now, hahaha!"

"Ling'er is really a process inspector."

"She can even tell how high the platform sign is held up."

"Zhao Lei is once again teetering on the edge of making progress."

Next is a simulated cabin crew announcement.

The children took turns using the microphone to broadcast.

Zhao Mengmeng said in her childish voice, "Please line up to get on the bus, don't push."

Zhou Xiaoyu added earnestly, "Children should hold their parents' hands tightly."

Chen Doudou picked up the microphone and said seriously, "There's food on the bus, but we can't run away just for the food."

The entire room fell silent for a second.

Then everyone laughed.

Lin Jia covered her face: "Is this a safety announcement or a restaurant safety notice?"

Shen Ling'er nodded: "Actually, it works."

Chen Doudou immediately became proud.

Shen Ling'er continued, "When people are looking for food in a car, it's easy for them not to look where they're going."

Chen Doudou became even more proud.

Zhao Lei laughed so hard he almost had to lean against the wall.

Finally, it was Shen Ling'er's turn.

She picked up the microphone, stood next to the simulated car door, her small face calm.

"Passengers, please watch your step before boarding."

"There is a gap between the platform and the carriage, so please don't look at your phone while walking."

"Parents with young children should ensure that their children walk in front of them and are in a position where they can see them, and should not let their children follow behind the crowd."

"Don't rush in when the car door is about to close."

"You can wait for the next train if you're late, but getting caught in the door will cause trouble for everyone."

"Please keep your luggage secure in the carriage and do not place it in the aisle."

"The train runs very fast, but people inside move a little slower."

After she finished speaking, she put down the microphone.

The platform simulation area was quiet for two seconds.

Engineer Luo was the first to applaud.

"This broadcast is very useful."

"Especially the last sentence."

"The train runs fast, but people inside move slower."

Zhao Lei looked at Shen Ling'er with a complicated expression.

"Teacher Ling'er, this clip of yours could be broadcast directly at the train station."

Shen Ling'er said seriously, "The station announcements should let people know what to do."

"If we only tell people to be careful, many people don't know what to be careful about."

"If we explain things more clearly, we'll make fewer mistakes."

Engineer Luo nodded.

"Yes, we can't just talk about safety in words."

The screen was instantly flooded with comments.

"This radio broadcast is really something!"

"Trains run fast, but people inside move slower—that's a great saying."

"She's not faking it; she knows where ordinary people make mistakes."

"Engineer Luo has already started the on-site certification."

At noon, lunch was served at the experience center's cafeteria.

The meals were very substantial work lunches.

Braised pork ribs, shredded potatoes, scrambled eggs with tomatoes, green vegetables, and seaweed soup.

Chen Doudou held the plate, her eyes shining as if she had found her life's goal.

"The high-speed rail canteen is also an option."

Lin Jia breathed a sigh of relief: "You're finally satisfied."

Shen Ling'er took a bite of the scrambled eggs with tomatoes and nodded.

"This dish is simple, but it's hot."

The director immediately looked at the assistant director.

The assistant director had already lowered his head to take notes.

[The high-speed rail experience center cafeteria served braised pork ribs and scrambled eggs with tomatoes, which were well-received by Shen Ling'er.]

Upon seeing this, Zhao Lei couldn't help but say, "Assistant Director, your book, 'Places You Can Eat,' has now been published in the railway system."

The assistant director said earnestly, "This will be used as a route reference later."

Shen Ling'er nodded: "Okay."

"If the food isn't good during the job experience session, everyone will lack energy in the afternoon."

"People who lack energy are more likely to just want things to end quickly."

"Then you won't be able to see things clearly."

Upon hearing this, Engineer Luo smiled and nodded.

That's true.

.........

in the afternoon.

The program crew arrived at the high-speed train maintenance depot.

The silver-white high-speed train is parked on the maintenance line, and it looks much bigger up close than it does on TV.

The front of the car is streamlined, the body is clean, and underneath are complex wheelsets, bogies and various pipelines.

As soon as the children came in, they all looked up at them.

Zhao Mengmeng whispered, "It's so big."

Zhou Xiaoyu's eyes widened as well: "It looks like a big white fish."

Chen Doudou looked at it carefully: "Can it hold a lot of rice?"

Lin Jia has completely given up on correcting her.

Engineer Luo said with a smile, "It can hold a lot of people, and the food is provided by the dining car."

Chen Doudou nodded: "That's still pretty impressive."

There are still a few staff members in the maintenance depot.

They are conducting routine checks.

Engineer Luo led everyone to stand outside the safety line.

"High-speed trains are inspected after each run."

"Check the wheels, brakes, pantograph, doors, air conditioning, seats, toilet; many details need to be confirmed."

"The reason why people find the ride smooth is because someone has been working behind the scenes to eliminate potential problems in advance."

Shen Ling'er looked under the car and nodded seriously.

"This place is ideal for early detection of problems."

Engineer Luo asked with a smile, "Why?"

Shen Ling'er said, "Because the car hasn't left yet."

"The car was found to have a problem here, it's just for repairs."

"If a problem is discovered after the car has been driven out, it will become a real hassle."

Luo Gong's eyes lit up.

"Absolutely right."

Zhao Lei immediately whispered to the camera, "Dear viewers, this is Teacher Ling'er's first lesson in the maintenance workshop."

"The problem was discovered before departure, so it was just a matter of repair."

Shen Ling'er nodded: "That's a good sentence."

Zhao Lei didn't shout this time.

He simply clenched his fist steadily.

Bai Sisi looked at him and couldn't stop laughing.

"You're really like someone who went on to graduate school after graduating with a bass voice."

Zhao Lei said earnestly, "I am currently studying for Teacher Ling'er's advanced course."

Everyone burst into laughter.

Engineer Luo first showed everyone the car doors.

The car doors were opened and closed repeatedly as staff checked the sensors and their closure status.

"The car door is very important."

"It must be able to be closed, but it must also be able to be opened when needed."

Zhao Lei listened attentively: "It's like a security door."

Shen Ling'er looked for a while, then suddenly pointed to the edge of one of the doors.

"This door closes a little slower than the ones next to it."

The staff member was taken aback.

Engineer Luo also looked over.

The car door opened and closed once more.

The average person can hardly tell the difference.

But Engineer Luo frowned and immediately asked the staff to retrieve the test data.

A moment later, the staff member said in surprise, "The closing time of this door is indeed a fraction of a second longer than the standard value, but it is still within the allowable range."

Zhao Lei slowly opened his mouth.

"You can tell in a fraction of a second?"

Shen Ling'er said seriously, "It's not about the number of seconds."

"It hesitated for a moment when it was closing the last part."

"Normally, the door should open smoothly all the way through."

"It was as if it was gently blocked at the end."

"It might be that the rubber strip is a bit stuck, or there's some dust in the track."

Staff immediately stepped forward to check.

Not long after, he cleared a small amount of sand from the edge of the door track.

The way Luo Gong looked at Shen Ling'er completely changed.

"There really is something in the tracks."

"Although it's small, if it's not cleaned for a long time, it will affect the condition of the car door."

Zhao Lei was at a loss for words.

Bai Sisi took a soft breath.

"Ling'er can even tell whether the car door closes smoothly or not."

Shen Ling'er looked at the door.

"A door isn't something that's good just because it's closed."

"To close smoothly, one must also open smoothly."

"Because it's driven many times a day, minor problems will be repeated many times."

Engineer Luo nodded solemnly.

"That's a very professional statement."

The live chat exploded.

"Holy crap! They can even tell a difference of a fraction of a second between the car door's dimensions?"

"She's not looking at the data, she's looking at whether the movements are smooth."

"Small problems will be repeated many times; that's a powerful statement."

"High-speed rail maintenance worker: Today, a five-year-old child reminded me to clean the door tracks."

Next, Engineer Luo showed everyone the wheelsets.

He pointed to the huge wheels and said, "When people ride in a car, they basically don't see the wheels."

"But the condition of the wheels is very important."

"Check for wear, cracks, and unusual noises."

Standing outside the safety line, Zhao Mengmeng asked softly, "Won't these big wheels be tiring?"

Bai Sisi laughed: "The wheels won't get tired, but they will wear down."

Shen Ling'er stared at the wheels for a while.

"The wheels are very clean, which means they check them frequently."

Engineer Luo smiled and nodded: "That's right."

Shen Ling'er then looked at the group next to her.

"But the rim over there is a slightly different color."

Engineer Luo was taken aback.

Several maintenance workers also looked over.

Shen Ling'er pointed very accurately.

"It's not bad."

"It's just that the ring of wear marks is brighter than the surrounding area."

"This indicates that it has recently made more significant contact with the orbit."

"It could be related to a curve in the track, the load, or the previous run."

This time, Engineer Luo didn't answer immediately, but went over to take a closer look.

The maintenance worker also squatted down to inspect.

A moment later, Engineer Luo looked up.

"you're right."

"The wear marks on the rims will be more noticeable after driving on a track with many curves."

"It's currently within the normal range, but it definitely needs to be recorded."

Zhao Lei raised his hand to his forehead.

"Teacher Ling'er, you mentioned all the maintenance items in advance today."

Shen Ling'er looked at him: "I didn't say it was bad."

"I'm just saying it's different from the ones next to it."

"When inspecting things, don't immediately declare a problem just because you see something different."

"First, write down the differences, then determine whether they are normal."

Engineer Luo immediately applauded.

"Well said."

"The two extremes are the worst for maintenance."

"One of them doesn't care about anything."

"The other one is someone who shouts nonsense over the slightest difference."

"A real check is about recording the differences and determining the causes."

Zhao Lei slowly said to the camera, "Dear viewers, this is Teacher Ling'er's second lesson on high-speed rail maintenance."

"Difference is not necessarily bad, but it is important to understand why it is different."

Shen Ling'er glanced at him.

"This sentence is also very good."

Zhao Lei was so happy that his ears turned red, but he still held back from shouting.

The comments section was filled with laughter.

"Zhao Lei really held his own today!"

"Difference is not necessarily bad, but it depends on why it is different. This statement can be applied to all industries."

"Ling'er is too strong. She's not creating tension, she's just explaining the judgment process clearly."

"Engineer Luo is completely convinced."

Next was the pantograph demonstration.

A massive archway rises, connecting to the simulated overhead contact line.

Engineer Luo explained, "High-speed rail relies on it to draw power from the overhead contact line."

"If the connection is poor, it will affect the power supply."

Chen Doudou asked earnestly, "Does it consume electricity?"

Engineer Luo smiled and said, "That's one way to understand it."

Chen Doudou nodded: "Then it's eating too."

Shen Ling'er looked at him and said, "That analogy makes some sense."

Chen Doudou instantly felt proud.

Zhao Lei laughed and said, "DouDou found the theory of everything eating in the railway system today."

Shen Ling'er looked at the pantograph and suddenly said, "It can't rise too violently."

Engineer Luo asked, "Why?"

Shen Ling'er explained, "If you're too rough, you'll hit the lines above."

"Too light, and the contact isn't good."

"So it's not about applying more force, it's about sticking to it just right."

"It's like trying to pick up tofu with chopsticks; if you're too light, you can't pick it up, and if you're too heavy, you'll break it."

Chen Doudou immediately nodded: "I understand!"

Engineer Luo smiled happily.

"This is a very good analogy."

"The pantograph does indeed require specific contact pressure."

Zhao Lei looked at Shen Ling'er, then at Chen Doudou.

"Teacher Ling'er can now explain the power supply of high-speed rail in a simple way, like using a tofu sandwich."

Shen Ling'er nodded: "Because he can understand."

Chen Doudou said earnestly, "We can't waste tofu either."

Everyone: "..."

The final step in the maintenance depot is to simulate troubleshooting.

Engineer Luo asked the staff to prepare a small control panel with several indicator lights on it.

"This simulates a train car air conditioning malfunction."

"You can use the hints to determine where the problem lies."

Zhao Lei immediately sat up straight: "I can give this a try."

Bai Sisi tensed up immediately upon hearing this: "You always say things like that..."

Zhao Lei quickly added, "I'll try it cautiously."

Shen Ling'er nodded: "This explanation is a bit safer than the one before."

On the panel, an indicator light flickered on and off.

Zhao Lei looked at it carefully for a long time: "Is the air conditioner broken?"

Engineer Luo laughed and said, "That's too general."

Zhou Xiaoyu whispered, "Is the power out?"

Zhao Mengmeng asked, "Isn't it too hot?"

Shen Ling'er stood in front of the panel, looked at it for a few seconds, and then looked at the simulated circuit diagram next to it.

"It wasn't the air conditioner itself that broke down first."

"The sensor data is unstable."

Engineer Luo raised an eyebrow: "Why?"

Shen Ling'er said, "If the air conditioner is really broken, the alarm should stay on."

"But this light keeps turning on and off."

"This means that the system sometimes thinks it's wrong, and sometimes it thinks it's normal."

"It's more like the detection data is jumping around."

"It could be a problem with the sensor contact, or the wire could be loose."

Engineer Luo looked at the staff.

The staff member nodded with a smile.

"The simulation does indeed show a problem with the temperature sensor's contact."

Zhao Lei froze.

"You can even watch this?"

Shen Ling'er said seriously, "A lamp doesn't just tell you whether it's broken or not."

"How bright it is will tell you what the problem is like."

"The reasons why someone keeps crying out in pain may be different from those who cry out intermittently."

Upon hearing the cry of pain, Chen Doudou immediately asked, "Do you need to take medicine?"

Lin Jia: "..."

Shen Ling'er looked at him: "This is a car, don't take your medicine."

Chen Doudou said with a hint of regret, "Then we can only repair it."

Engineer Luo couldn't stop laughing.

He looked at Shen Ling'er, his tone already showing obvious admiration.

"Little friend, what impressed me most about you today wasn't how much you know about high-speed rail."

"It's that you're particularly good at seeing the logic behind phenomena."

"This is important for any maintenance work."

Shen Ling'er thought for a moment.

"Many things will reveal a little bit of their appearance first."

"The car door is not working properly, the lights are flashing strangely, and the wheels are a different color."

"They're not trying to scare people, they're trying to remind them."

"If someone sees it, they can deal with it in advance."

"If no one sees it, it will become a big problem."

Engineer Luo was silent for a few seconds, then nodded seriously.

"I think our entire maintenance depot should remember this sentence."

Zhao Lei immediately looked at the director.

The director has already looked at the assistant director.

The assistant director has already opened the memo.

[High-speed rail maintenance: Minor anomalies serve as reminders; early detection allows for timely intervention.]

Zhao Lei: "..."

Bai Sisi laughed uncontrollably: "You guys are getting more and more skilled now."

The director said seriously, "Record it if it's useful."

As the afternoon drew to a close, the experience center gave each child a small high-speed rail model.

Zhao Mengmeng happily hugged the little car.

Zhou Xiaoyu carefully put the model into the bag.

Looking at the model, Chen Doudou asked, "Can I draw food in this train carriage?"

Lin Jia was exhausted: "Go ahead and draw if you want."

Shen Ling'er held her small model and looked at the wheels.

"This model is pretty good."

Engineer Luo asked with a smile, "Where is it alright?"

Shen Ling'er said seriously, "Although the wheels can't really run very fast, they have raised edges."

"This means it wasn't just about randomly making four round pieces and pasting them on."

"The front of the car also has some streamlined lines; it's not just made into a white box."

"Things given to children should be made to look exactly like they are."

Engineer Luo smiled.

"Is this also a form of recognition?"

Shen Ling'er nodded.

"Yes."

Engineer Luo seemed even happier than when he received the award certificate.

As he left the experience center, Zhao Lei quietly summarized to the camera.

"Dear viewers..."

"Today's high-speed rail career experience was something we originally thought was just visiting the trains."

"As a result, Teacher Ling'er was able to understand the dispatching diagram, the platform guidance, the door track, the wheel flange wear, the pantograph pressure, and even the sensor malfunction."

"Most importantly, she explained every complex thing in a way that everyone could understand."

Shen Ling'er glanced at him.

"This summary is quite comprehensive."

Zhao Lei sat up straight instantly.

"Fully verified!"

Bai Sisi quickly pressed him down: "Keep your voice down."

Zhao Lei immediately lowered his voice: "Full verification."

That evening.

Unsurprisingly, the topic of "high-speed rail job experience" quickly became a trending topic.

The hotel room.

Shen Ling'er put the mini high-speed rail model into her suitcase and placed it together with the mini fire truck, weather vane commemorative plaque, and mini sachet.

Yang Mi looked at the row of things and asked with a smile, "Do you like the high-speed rail today?"

Shen Ling'er nodded.

"like."

Yang Mi asked, "Why?"

Shen Ling'er thought about it seriously.

"It runs very fast, but the people behind it are very steady."

"Stable dispatching, stable maintenance, and stable platforms are also essential."

"That's why when people sit on it, it just seems to be moving forward normally."

Yang Mi's eyes were gentle.

"Even running forward in an ordinary way is not easy."

Shen Ling'er nodded.

"right."

"The more ordinary and smooth things seem, the less you can afford to slack off behind the scenes."

The next room.

Zhao Lei posted another message on his WeChat Moments.

[Learning Outcome from the High-Speed ​​Rail Experience: The railway's biggest fear is being too similar. Minor anomalies serve as reminders.]

[Shen Ling'er's assessment: A fairly comprehensive summary.]

After reading it, Bai Sisi smiled and asked, "Are you waiting for her to give you a verification message every day now?"

Zhao Lei was very serious.

"This is the spiritual fuel for my career experience season."

Bai Sisi couldn't stop laughing.

Outside the window, the city lights shone quietly.

The high-speed rail line cuts through the night in the distance, like a silver thread.

There were no thrills or disputes at this stop.

The only things on the screen are the operation diagram, the yellow lines on the platform, and the doors, wheels, and indicator lights in the maintenance depot.

But the audience still couldn't stop watching.

Because Shen Ling'er always manages to make sure everyone sees her.

The truly remarkable things often don't emerge with a bang.

Instead, they take preventative measures to address potential problems before each trip.
