When the fuel is compressed to a certain degree of air through the engine, the spontaneous ignition temperature of the fuel is lower than the internal energy temperature generated when the air in the engine is compressed, so the fuel is ignited after the intersection of the two, and a large amount of internal energy is released, causing the air pressure in the cylinder to rise rapidly, pushing the mechanical parts to convert it into mechanical energy, so that the car can act, which is the operating principle of the car.

It is no exaggeration to say that even a friend for many years may scratch his car because of your inadvertent scratches, even if it is as fine as a hair, it is enough to make him break off your friendship with you.

Hannam people regard the car as very important, it is a thing comparable to housing and money, and some people even rank the above three things above friendship in the ranking of the most important things in their hearts.

In the eyes of the people of South Korea, as long as the economy is still good, they will buy a car, which is considered a symbol.

When it comes to Hannam Motors, I have to say a famous brand, Kia!

Kia, as the earliest automobile manufacturer in South Korea, has a history of nearly 163 years, it is the first real automobile production company in South Korea, its early days was just a workshop called Gyeongseong Precision Industry, and later moved to Busan, officially changed its name to Kia Industries in 52 years, and officially produced the first bicycle called Samkiri in South Korea.

In '61, Kia officially produced the first C-100 motorcycle, and since then, Hannam's motorcycle industry has been born.

With the development of the motorcycle industry, it only took one year for the first box tricycle K360 to be officially launched!

Taking advantage of the growing trend of three-wheeled vehicles, Kia Service Company was established in 71 Kia to provide warranty maintenance for three-wheeled vehicles sold, and intended to develop four-wheeled vehicles in the direction of three-wheeled vehicles.

In the same year, Kia launched the four-wheeled van Titan, due to the rapid economic development of Hannam at that time, this lightweight utility truck was favored by some new entrepreneurs or self-employed people, and sales soared, the Titan brand was almost ubiquitous in South Korea, and Titan became the common name for almost all trucks.

In 73, Kia produced Hannam's first gasoline engine, and the following year, Kia launched the first passenger car with a gasoline engine, the Brisa, and since then, Kia has begun to connect with the world's car manufacturers, and with Brisa as a pioneer to enter the highly competitive sedan market, and Brisa has become the first car exported to Hannam.

In '78, Kia produced its first diesel engine.

In order to meet the increasingly discerning requirements of customers, and in order to adapt to the development of the times, coupled with design problems, Kia finally decided to reform, first of all, we must first learn from the production experience of foreign advanced models, so in 79 years, Kia Motors imitated the French Peugeot brand 604 sedan, and assembled the Italian Fiat 132 model sedan, constantly absorbing the wisdom of others to enrich themselves, for long-term development, Kia decided to set up a Kia RD center responsible for technical research and new product design

In '81, Kia was designated as a van manufacturer by the Hannam government.

With the pace of the times, Kia has also joined forces with foreign companies, and through the share exchange system, it has reached cooperative relations with well-known foreign car manufacturers Miliken Ford Motor and Shimari Mazda, and in this way, international multinational companies occupy 20% of Kia's shares.

Backed by new financing and new technologies, Kia's development has been unstoppable, like a brave general who has broken new ground, and has built a generation of Kia dynasties wherever the sword is pointed.

Career is like life, there is prosperity, there is decline, the king of the territory laid this great country, but the descendants did not keep this foundation well, but focused on developing overseas, everywhere contaminated in other fields, such as metallurgy, construction, real estate, etc., since then, Kia finally embarked on the road of no return to the twilight of the hero.

In 97, the financial turmoil that swept through Asia brought the emperor named Kia, which meant to 'rise from the East and rise in Asia', to an incurable terminal illness.

Kia, which had incurred huge debts due to its focus on overseas expansion, was unable to repay its heavy burden and announced that it had entered a state of liquidation amid the financial turmoil.

Later, the government stepped in and ordered Hyundai to acquire Kia.

In 98, Kia finally signed a share transfer agreement with Hyundai, which is also a Korean automobile giant, and since then, a generation of rivers and mountains has been given away.

In the 00th millennium, after the completion of the rectification, Kia finally established Hyundai Kia Motors Group together with Hyundai, with Hyundai's huge capital chain and technical support, Kia finally ushered in a new life, but unfortunately, today, Kia Motors, which used to dominate Hannam, can now only be reduced to a supporting role, and the honor of Hannam's first car has gradually been replaced by Hyundai.

Now Li Shenglong is in a car sales point in Hyundai, with the enthusiastic help of the shopping guide, learning about the gorgeous and cool sports cars.

According to the theory of mechanics, the theory of air convection, what unique streamlined design, what high-strength alloy smelting technology, and professional noun theories spit out from the mouth of the shopping guide, trying to use these complex scientific knowledge to bluff Li Shenglong stunned.

However, it was useless, and after seeing and understanding, Li Shenglong finally chose a simple car.

Hyundai Z800, a relatively large SUV model, at first glance, is also a little mistaken for a van, but it is different from a van, its performance is good, the volume is large, the price is suitable, in a simple word, cost-effective.

There is only one reason why Li Shenglong chose this car, it is a common artist nanny car, but Li Shenglong bought an 8-seater, which is considered a high configuration, and after paying an extra modification fee, he can also make certain changes to the interior layout of the car according to his own ideas.

So after paying a modification fee of 5 million won, the 6-person seats in the back of the car were all dismantled, and a special small sofa was placed along the edge of the car facing the center of the car, which can be stretched and merged into a cushion that can lie down, and the car is also covered with a soft carpet. You can also sit or lie on the carpet vacated in the center to play games and chat.

It takes a certain amount of time to modify the vehicle, and after paying off seventy percent of the car, they need to rebuild the car before settling the remaining car.

Just after completing the formalities here, Li Shenglong, who was about to leave, received an unexpected phone call.

"Shenglong, it's me!" A magnetic middle-aged man's voice, Li Shenglong is very familiar with it, it is his music enlightenment teacher Zheng Chunyuan, stage name TheOne.

"Hello teacher, what's the matter?" After the respectful greetings, Li Shenglong wondered what the teacher was looking for him.

Since returning to Hannan, I have only had a drink with the teacher, and I got together for a while, and I don't seem to visit the teacher much these days, thinking of this, Li Shenglong is a little embarrassed.

Zheng Chunyuan's voice sounded a little hurried: "This...... Shenglong, can you go to S.M for me to take a few singing classes? ”

"......" Li Shenglong was a little doubtful that his ears could hear clearly, so he let himself go to the top class? Such an outdated artist who has not yet returned to teach at S.M, where everyone has a great cause?

Hehe......

"Did something happen to the teacher?" Li Shenglong did not answer, but asked him about his situation with concern.

"That's it...... As for my girlfriend's business, ahem, I have to leave for a while, so I'll leave it to you. I've already informed you from S.M's side, and I believe you, you're my disciple! Come on! Zheng Chunyuan couldn't help but say that he gave things to a certain point, and before Li Shenglong could even say a word, Zheng Chunyuan was already impatient.

Looking at the blacked-out mobile phone screen, Li Shenglong was a little speechless, what is going on with the usually steady teacher today?

'Didn't you make your girlfriend's belly bigger, and your girlfriend broke up again? Li Shenglong maliciously imagined this in his mind.

"Ding Dong!"

New SMS!

"Shenglong, don't forget to check in for me, I'm full of work all year round, don't break it for me!"

"Uh...... All right. Li Shenglong replied to Zheng Chunyuan's message speechlessly, and then received the class schedule from Zheng Chunyuan.

As it happens, there are 2 lessons this afternoon.

"S.M, ah ......" got on the bus, and directly typed the name of S.M company on the navigation system, and did not even need to enter the location of Apgujeong 2 hole, after all, S.M is a small brand.

It took some time to come to the vicinity of S.M, in order not to attract too much attention, Li Shenglong still parked his car in front of a restaurant 2 streets apart, and by the way, he also had a meal first, the time of class was around 1 o'clock in the afternoon, and now there is still an hour to spare, as for what to teach, this is just a good teaching, anyway, from the information sent by the teacher, I know that the students in his course are basically some trainees who have good singing skills and need to be more sophisticated.

On the class list, Li Shenglong saw some familiar names, a smile on the corner of his mouth, and sent a message with his mobile phone.

In the S.M company's restaurant, a group of girls sit together for lunch, and a girl's phone vibrates.

The girl stopped what she was doing, took out her mobile phone and looked at it, her expression was slightly surprised, and the girl next to her stretched out her head to take a look.

"I'll surprise you in the afternoon, won't you? Taeyeon, what a surprise? Pani read the message as she looked, then asked Kim Taeyeon.

"It's not a surprise to know! Prabhu! Kim Taeyeon glanced at her speechlessly, put away her mobile phone and continued to eat, although the meal was just simple shredded vegetables and kimchi, and the taste was not very good, but if you don't eat it, it will take a lot of physical strength to practice in the afternoon, and I am afraid that it will be unbearable.

"Sicaoni, can you give this to me if you don't eat it?" Lin Yun'er quickly eliminated the lunch in front of her, and then aimed her deer-like pure eyes at Zheng Xiuyan, who was a picky eater, and the dish of kimchi that had not moved was touched, and her eyes kept emitting the meaning of 'I want to eat'.

"Hmm." Zheng Xiuyan responded lightly, and filled the mouth with rice for a while, and then chewed it mechanically.

"Hee-hee!" Lin Yun'er laughed, ignored Zheng Xiuyan, who was also free to eat, and quickly took the plate of kimchi to herself and enjoyed it.

"Hey, how long has this kid been hungry? What a pity! Jin Xiaoyuan next to him looked at the greedy Lin Yun'er and couldn't help sighing.

Lin Yun'er's movements in her hands kept moving, looking at Jin Xiaoyuan, her mouth was eating and her speech was blurred: "Xiaoyuan, Ernie, do you want to give me food too?" ”

"Uh, I need stamina too!" Jin Xiaoyuan hurriedly covered his plate and stared at her as if he was facing a great enemy.

"Cut, stingy Ernie!" Lin Yun'er muttered, and then focused on being her own foodie.

After lunch, the rest time also passed quickly, and soon the trainees also devoted their time to non-stop training to improve themselves.

Zheng Xiujing happened to be sleepy after eating, and she didn't want to move lazily, but the time to practice was up, and she had already taken a lot of leave before, so she couldn't be lazy anymore, so she was helplessly pulled by Cui Xueli step by step to the practice room.

When she was about to walk into the practice room, a touch of white flickered from the corner of her eyes, Zheng Xiujing blinked, and when she looked again, there was no one at the corner of the stairs, and I don't know if it was an illusion, it seemed that she saw Li Shenglong?

Thinking about it, Zheng Xiujing took out her mobile phone and planned to ask Li Shenglong, what did she expect, but a familiar voice sounded behind her.

"Zheng Xiujing, may I ask what you are doing blocking the door?"

It's the teacher!

Zheng Xiujing moved sideways and took the phone back at the same time.

"Hello teacher!"

"Eun, come in and start practicing!"

'Hi...... Here we go again! Zheng Xiujing sighed in her heart, and the tired dance class was about to start again.
