Comeback 1992

Pretty is right.

Han Yumeng curled her lips: "Dad, Han Xuan only plays with pretty kids, it's wrong to judge someone by their appearance."

Han Yufei glanced at Han Yumeng in surprise, and wanted to say: Don't you only play with people who can help you make money?

Han Yumeng didn't even have a child who really played well at school.

Regarding Han Yumeng's situation, although Han Yufei is not at Red Star Middle School, she knows quite well, because Han Yumeng usually talks to Han Yufei about many things when she comes back.

Although Han Yufei just listened, when he was in a good mood, he would respond to her.

"People are always vulgar. It's wrong to judge people by their appearance." Han Songlin said, he is also a vulgar person!

Han Xuan: "I don't judge people by their appearance. I think all the children in the class are beautiful."

Are they all beautiful?

Maybe it is.

Ugly or not depends on how you dress.

"Okay, hurry up and wash your hands, and get ready to eat."

The family sat at the dining table and talked.

Han Songlin found that Han Yumeng and the others were quite relieved.

Don't worry about whether the homework is done or not, and don't worry about the study situation.

Everything is perfect.

At the dinner table, Liu Yuyan hesitated for a moment, and asked Han Yufei, "Qiuqiu, has your Riemann conjecture been proved?"

"Now only the second proposition has been proved. As for the third proposition, I have to think about it."

Liu Yuyan doesn't care about the second proposition.

Anyway, I just know that my daughter is super powerful.

Involuntarily, Liu Yuyan smiled on her beautiful face, and gave Han Yufei a chicken leg: "Qiuqiu must be tired, eat more, and nourish your body."

Han Yufei didn't refuse, she also liked eating chicken drumsticks.

Han Songlin picked up the food and ate slowly, but he was thinking about how much disturbance would be caused around the world if Han Yufei really proved the Riemann Hypothesis.

For the next few days, Han Yufei didn't stay at home.

And went to Star University.

What to do?

Of course, I went to discuss with a group of professors.

Not only the mathematics professors all came, but even the other academicians of the Star Academy ran over after hearing that Han Yufei had proved the second proposition of Riemann's conjecture.

Han Songlin also came over to take a look and took photos.

Looking at Han Yufei's high-spirited appearance in the camera, in Han Songlin's view, that's it.

In fact, Han Yufei behaved quite calmly.

In a short period of time, Han Yufei uploaded the whole process of proving the second proposition of Riemann's conjecture on Xingchen.com.

The thesis written by Han Yufei has a very important feature, that is, the steps are extremely clear and concise.

Although undergraduate students can't fully understand it, it is still no problem for doctoral students to understand Han Yufei's thesis.

In addition to publishing on Xingchen.com, Han Yufei also sent a paper to "Hua Guo Mathematics Journal".

"Acta Mathematica Sinica" had been waiting for Han Yufei's paper for a long time, and after receiving the paper, it directly published it intact.

A special issue has been published!

In addition to publishing a Chinese special issue, an English special issue was also issued.

Riemann's conjecture has too much influence on human beings.

Even before, the correctness of Riemann's conjecture has been proved in other ways.

But this kind of side proof does not mean that this is absolutely correct.

In the already hot summer, it was like being dropped a boulder, causing huge waves.

Han Yufei's proof paper has been widely spread in Huaguo mathematics circles.

As far as mathematics is concerned, Huaguo is not said to be backward in the world, and mathematicians are also talented.

Compared with other subjects that cost countless dollars, mathematics research is ridiculed and only needs a brain, a pen, and a piece of paper!

The mathematicians in Huaguo had read Han Yufei's proof paper, but they couldn't find any problems at all.

It is common opinion that Han Yufei has indeed completed the proof of the second proposition of the Riemann Hypothesis.

This proposition that has troubled mankind for a century and a half has been proved.

And, it is proved in a way that everyone can understand.

In August, Han Songlin closed the page on the computer.

In this summer, the two most popular events: Han Yufei's proof of the second proposition of Riemann's conjecture, and the Creation Camp.

Of course, although the Riemann conjecture is important, it has great significance for the development of human science and technology.But to Han Songlin, these are all empty-headed things.

After turning off the computer, Han Songlin got up and walked out.

Today Han Songlin will go to a ceremony.

Nok Air's first flight!

In mid-July, Flying Air officially received the first MA700 aircraft from Xinghai Xifei.

The first flight will be the route from Chengdu to Chang'an.

The shuttle bus is carrying passengers over to board the plane.

On the first flight, there were actually 59 passengers, and the occupancy rate was 80.00%!

This attendance rate is quite good.

Flying Air is very clear in its development positioning, and it will be a low-cost airline.

Airfare is super cheap.

In order to save passengers' waiting time, passengers who buy tickets online and do not check in their luggage can check in directly by phone.

Needless to say, I ran to the airport two or three hours in advance and waited.

After a brief ceremony, the plane was officially launched.

"Today, it's a good start. Next, the development of Feique Aviation depends on you."

In order to let the MA700 fly, a special airline was established, which is not bad.

Han Songlin also hopes that other airlines can order some after seeing the excellent performance of MA700.

Chapter 873 Special Lecture Meeting

Flying Sparrow Airlines can definitely be regarded as having a high starting point when it started.Xinghai Group, Skyfire Hammer Investment, Jiangzhong City Investment and Rongcheng Investment are all shareholders of Feique Aviation.

As for Xinghai Xifei?

Xinghai Xifei now has no money to invest in Feique Airlines.

The logo of Flying Bird Airlines is a bird with wings spread.

Although the bird is small, it has great ambitions!

Flying Sparrow Airlines also cooperates with the China Civil Aviation Flight Academy to train pilots, but there is no shortage of reserve talents.

Flying Bird Airlines will open more routes in the future, from Rongcheng to Chuncheng, from Rongcheng to Qianzhou, and so on.

In addition, the layout will be carried out on routes suitable for MA700.

For the Xinzhou 700 aircraft, the country is naturally very supportive.

In Huaguo's own sky, Huaguo's own civil aviation airliner is finally flying.

"The MA700 is a new aircraft, and maintenance must be done well."

"Boss, don't worry, Xinghai Xifei will take us to do the maintenance of the plane, and there will definitely be no problems."

As an airline, it is very important for aircraft maintenance to have the full support of the manufacturer.

Xinghai Xifei also attaches great importance to after-sales maintenance.

If you want the airline to use your plane, you have to do your best to ensure that the plane can fly in the sky.

For airlines, it is absolutely unacceptable that planes cannot fly into the sky.

The flight is all arranged, but the plane can't fly?

This blow to airlines may be a bit big.

In the next period of time, all kinds of good news will continue.

It is confirmed that Tianfu Airport will be officially open to air in September, and the cargo planes of Flying Air will be completely transferred to Tianfu Airport.

For Rongcheng, the benefits of Tianfu Airport's navigation are also extremely great.

In the future, electronic products and so on can be directly transported from Tianfu Airport to all parts of the country, and even all parts of the country.

Han Songlin looked at Cao Yangwen thoughtfully.

Huaguo's civil aviation transportation industry has not developed for a long time, but its development speed is extremely fast.

In 2004, the total turnover of civil aviation transportation in China reached 230 billion ton-kilometers, ranking third among the 188 contracting states of the International Civil Aviation Organization.

The rapid development of civil aviation transportation has naturally created a large number of talents.

Cao Yangwen is one of them.

Worked as a captain and then turned into management, and then came to the newly established Feique Airlines as the general manager.

Such a life experience is definitely rich.

In order to invite Cao Yangwen, Xinghai Group also paid a lot of money.

"I believe Mr. Cao!"

Cao Yangwen smiled lightly and said, "We must live up to the trust of the boss."

Han Songlin didn't stay at the airport too long. After attending the first flight ceremony, he went back directly.

As a private airline, Flying Air will be under greater pressure in terms of operation.

It's just that now is a period of rapid development of civil aviation, or the best era.

The speed of the train at 160 kilometers per hour is increasing rapidly, but compared with the speed of the plane, it is still a bit worse.

The era of high-speed rail has not yet arrived, and the fastest means of transportation is still the plane.

As a low-cost airline, Flying Airlines will definitely attract a large number of people who did not take the plane before to switch to the plane.

Known from the very first flight of Sparrow Air.

Think about the advent of the high-speed rail era in the future, and the civil aviation industry has ushered in a large-scale reshuffle.

The one who defeats you may not necessarily be your opponent, but may also come from another industry.

At home, Han Yufei was unexpectedly at home today, holding a Rubik's Cube and fiddling with it.

Seeing Han Songlin coming back, Han Yufei greeted him, staring at Han Songlin, but her hands kept moving.

The Rubik's Cube is restored.

Han Songlin could see it, but he didn't know what to say.

It's better not to comment.

"Where did this Rubik's Cube come from?"

Han Yufei scrambled the transformed Rubik's Cube again, and put it on the tea table: "Han Xuan bought it from the supermarket."

Han Xuan bought it!

Han Xuan also has pocket money every day, but Han Songlin and Liu Yuyan treat each other equally.

Han Songlin picked up the Rubik's Cube and looked at it, but he didn't intend to get started.
