You can't believe that talent is credible.

Because any successful person depends on more than just the word talent.

But through hard work.

There is a courier brother in Henan.

Live your most ordinary life.

But he is also subverting his own genius creation.

The courier's name is Yu Jianchun, and he is 33 years old.

Why do you want to say that he has completed subversive creation?

Because Yu Jianchun, a seemingly ordinary person, has attracted the attention of the whole world!

If you want to know Yu Jianchun, you must start from his youth.

Dream in my heart

He was born in a rural family.

Both parents are simple farmers with ordinary family conditions.

Besides, Yu Jianchun is a real dropout.

Unlike those young geniuses, Yu Jianchun took a different road!

After nine years of compulsory education, Yu Jianchun graduated from high school.

His grades are really not bad, and he can't get into high school at all.

You should choose a junior college at a young age, especially a vocational high school.

After graduation, he did a lot of jobs without much skill.

Such as workers, security guards, and finally settle down and become couriers.

Yu Jianchun does the most common logistics and packaging work.

But that doesn't stop him from dreaming forever.

I believe that everyone wrote their own ideals when they were young.

If we are imaginative or unrealistic, we can think about the time of day in the distance.

When we grow up, we will find our childhood ideals lovely and ridiculous.

Most of them will fade with time.

Yu Jianchun also has a dream.

That is to be a mathematician!

Poor grades are true, and interest in mathematics is also true.

Yu Jianchun doesn't know many advanced arithmetic.

But he likes doing all kinds of calculations very much.

Did not receive higher professional education.

Yu Jianchun teaches himself in his spare time, which is his unique way to relax himself.

Mathematics is a whole vocabulary.

It summarizes countless mysteries and hides endless stories and history.

Yu Jianchun was deeply attracted by the universe in mathematics.

If he has nothing to do, he can study a math problem all day!

If you go to his room.

You will find his handwriting on many pieces of paper.

Because my professional knowledge is not strong enough.

Formed Yu Jianchun's studious and happy attitude.

The identity of the courier makes him often run around and have the opportunity to enter and leave major universities.

Whenever he has time, he will humbly ask teachers in colleges and universities for advice.

Let them give some advice to the older students.

This time lasted for more than ten years.

A courier who travels all over the city, his inner dream is fermenting and expanding.

Yu Jianchun is eager for recognition.

hope

Of course, he himself has made great achievements.

One day is the most surprising day in daily reasoning and calculus.

On that day, Yu Jianchun found that he might have solved a world problem.

This topic is called "Carmichael number", also called "absolute pseudo prime number".

American mathematician carmichael discovered this mathematical law in 19 12.

Because of its complexity and influence, its appearance once caused a sensation in the world.

Similarly, it has become one of the problems that plague the world.

For more than a hundred years, countless people have tried to crack it.

But even the most authoritative mathematical experts can't do anything about it.

Yu Jianchun tempted, this is a great question!

While he is happy, he also wants to tell others about his achievements.

And the only way he can think of is to send his calculus manuscript to the university professor.

And authoritative experts in some professional fields.

The manuscript sent by a courier did not attract everyone's attention and response.

Those dense manuscripts are also like a stone.

Yu Jianchun was disappointed and frustrated.

The world is indifferent, but knowledge should not be indifferent.

June 20 16, Yu Jianchun finally ushered in its own spring.

A swift horse meets Bole, and his Bole is Professor Cai Tianxin.

Cai Tianxin heard that Yu Jianchun may have solved the century problem.

It is also incredible. But he chose to trust this simple young man.

Opening his manuscript, I saw those formulas with only lines.

Cai Tianxin has some trance, of course, more admiration.

The content in Yu Jianchun's manuscript is not fiction.

Even the calculation of continuous table cubic number and natural cubic number is included.

The difficulty is more than many famous schools in the sky!

Yu Jianchun is a rough diamond!

Cai Tianxin understands Yu Jianchun's pursuit.

So he took him to a seminar.

At that seminar, experts and doctors from all walks of life came.

Cai Tianxin came in with a strange, even plain Yu Jianchun.

The classroom, which was hotly discussed, suddenly became quiet.

They are talking about Carmichael number, and everyone has different opinions.

Didn't get the exact answer.

Yu Jianchun's previous manuscripts were published on the Internet platform.

Netizens are also full of curiosity about this Henan courier.

Obviously, some of the experts present did not know Yu Jianchun.

Laughter and buzz exploded in Jianchun's ear.

Now on the blackboard, Yu Jianchun's hand holding the chalk is obviously shaking.

This is the first time that he has been concerned by so many people.

He knew that others might be up to no good, but he wrote down his own calculation process completely.

He made mistakes in the process of writing, and he was anxious to erase the chalk words with his hand.

But in any case, the correct result is impressively displayed on the blackboard!

Those doctoral experts were dumbfounded and had to obey!

Yu Jianchun doesn't know much. He can only solve Carmichael number in one way.

And this result may be done by mistake.

But Yu Jianchun succeeded, which is an indisputable fact.

He solved the century's problems and deserves to be the first person in the world!

Longing for family

Everyone is proud of Yu Jianchun.

Praise and fame from all directions came uninvited.

Yu Jianchun has obviously become a successful person, and fame and fortune are just around the corner.

In an interview with reporters, Yu Jianchun spoke his true thoughts.

He said that he worked outside all the year round and didn't spend much time with his parents.

When wandering outside, his most obvious feeling is that he is too lonely.

Fame and fortune are not important, but finding a wife is the most important!

What Yu Jianchun, 33, wants most is a warm home.

Mathematics is a dream and a sustenance for him.

It is the most interesting companion in your plain life.

Not a tool to pursue fame and fortune!

Yu Jianchun's remarks are even more admirable.

Fully show his indifferent quality of fame and fortune!

He is also a veritable math expert in our minds!
