Qiao's Four King Kongs became famous after the international subprime mortgage crisis in 2008.

At that time, the "five major investment banks on Wall Street" fell one after another, the risk management and control systems of the major investment banks were all paralyzed, and the world investment community stagnated for a long time.

At this time, Qiao Tianyu, an ace trader at Goldman Sachs, was ordered to personally set up a new risk management and control team.

Qiao Tianyu led four of his little-known risk analysts to reconstruct the world's new risk management and control system and create a new world risk management and control system.

It is widely recognized and respected by the world investment community, and is regarded as the new "bible" of risk management.

Since then, Qiao's Four King Kongs have escorted Qiao Tianyu for more than 30 years, helping Qiao Tianyu become famous and famous all over the world, becoming an extremely rare "winning general" in the world investment community!

It is no exaggeration to say that the success of Qiao Tianyu in the previous life is largely due to the four King Kongs of the Qiao family, who single-handedly created the myth of the world investment community, created a generation of legends, and also became a generation of legends.

Now that Qiao Tianyu is surrounded by strong enemies, he feels a deep sense of helplessness, and it is time to ask for help.

However, Qiao Tianyu understood that in terms of the current situation, there was no need to awaken the four King Kongs at the same time, only one of them was enough.

That is the Li family line known as "Young Riemann".

Li Jiaxing, Chinese, 15 years old, is the youngest tenured professor in the history of the Department of Mathematics of Harvard University, doctoral supervisor, and the founder of the "Li Shi Base Number", "Li Style Great Theorem" and "Li Style Conjecture" that shocked the world!

He was born into a family of mathematics, his parents were both university mathematics teachers, and he was gifted from an early age, loving mathematics and being particularly sensitive to numbers.

At the age of 7, he participated in the International Mathematical Olympiad (IMO) and won the first prize with a perfect score, and entered the Department of Mathematics of Harvard University without examination.

Li Jiaxing graduated with a doctorate in mathematics at the age of 10 and stayed at Harvard University to teach;

At the age of 11, he became a doctoral supervisor and was awarded a tenured professor at Harvard University.

At the age of 12, he was elected to the National Academy of Sciences;

At the age of 13, he was hired as a senior researcher at the most famous National Institute of Mathematical Sciences in the United States;

At the age of 14, he was pleased to mention the world's highest mathematics award, the Fields Medal!

In the world of mathematics, Li Jiaxing is known as the young Riemann, is recognized as the most talented mathematical genius since Riemann, and is the greatest wealth in the world mathematics community today!

However, Li Jiaxing is not very popular in the mathematics circle, mainly because of his arrogance, to put it bluntly, he is crazy!

He was sullen all day long, and he wore a dead donkey's face all day long.

The reason he gave was that Invincible was so lonely, there was no opponent for him in the world, and his greatest wish in life was to fail once.

It's crazy!

Because he was invincible, he turned his attention to the ancients, and by solving those historical problems that were difficult to solve for hundreds of years, he fought with mathematical giants such as Riemann, Gauss, and Fermat, as if this was the only way to fill the emptiness in his heart.

But then again, people are crazy and have crazy capital, who makes people so good!

For Li Jiaxing's arrogance, some people have long been unpleasant, every year there are countless talented young mathematicians to ask him for tricks, but they have been defeated one after another, without a victory.

It also fueled Li Jiaxing's arrogance even more, he once publicly issued a statement that as long as anyone can defeat him once, he promised that he would never enter the mathematical world again in this life!

However, this scene never happened.

Qiao Tianyu came to the Department of Mathematics of Harvard University with ease, and found Li Jiaxing's research room with his memory.

This is his main battlefield, and he spends at least 18 hours a day, 24 hours a day.

Today, however, Harvard's mathematics department is closed and empty.

After inquiry, I learned that the entire Harvard Department of Mathematics was in Massachusetts Hall today to participate in the major celebration of Li Jiaxing.

A big celebration in Massachusetts Hall?

What kind of award does this guy like to mention?

Know that Massachusetts Hall is the oldest and most sacred building at Harvard University, and only Harvard's biggest celebrations are eligible to be held there every year!

No wonder when I passed by the Massachusetts Hall just now, I saw that it was crowded, as if there was a major event, and it turned out that the buddy of Li Jiaxing had turned on the hanging mode again.

Hey, the life of the open is really envious, jealous and hateful!

Qiao Tianyu returned to Massachusetts Hall, only to know that the United States National Team was celebrating the first place in the overall score of the 35th International Mathematical Olympiad (IMO) that had just ended!

Hearing this, Qiao Tianyu suddenly realized that there was indeed such a thing in the memory of the previous life.

Here's how it happened.

The International Mathematical Olympiad is the highest competition in the international mathematics community, and since its official opening in 1894, the United States has been dominating the competition in this competition.

However, that all changed in 1985.

This year, China sent a team to participate in the International Mathematical Olympiad for the first time, and since then the Chinese national team has risen rapidly, surpassing the United States to monopolize the first place in the overall score of the event in one fell swoop.

The United States has been suppressed by China for many years, and it has not tasted the taste of being the first in the overall score for a long time.

The successive defeats in the highest competition in the mathematics competition made the American Mathematical Association lose face and become angry, and they made up their minds to fight a beautiful turnaround.

So the American Mathematical Association selected the best mathematical geniuses from all over the United States and invited Li Jiaxing to serve as the head coach of the U.S. national team to prepare for the 1994 IMO.

At that time, when the American Mathematical Association invited Li Jiaxing to go out of the mountain, Li Jiaxing seemed to have found a new goal in life, and agreed to it.

And his reason is very simple, in this life, he has only been elected president of the United States and led the national team to win the international Olympic Games.

It's crazy!

Under the leadership of Li Jiaxing, from July 8 to 20, 1994, in the 35th International Mathematical Olympiad held in **, the U.S. national team finally got its wish and won the first place in the overall score with a narrow score!

Therefore, today in the Massachusetts Hall of the Harvard University Temple, the American Mathematical Association held a grand celebration ceremony to thank Li Jiaxing for helping them save face, and Li Jiaxing has once again become an American hero!

In fact, in response to this matter, Qiao Tianyu and Li Jiaxing had a fierce quarrel in the previous life.

Qiao Tianyu very much disagrees with him leading the U.S. national team to compete with the Chinese national team, which is an unreasonable thing for Qiao Tianyu.

However, the reason given by Li Jiaxing is that he is already a fourth-generation immigrant, and he has never returned to China, so he has no concept of Huaxia at all.

Besides, Lai only saw this as a personal challenge, and he never had the idea of national competition in his head.

Moreover, when it comes to patriotism, he himself is already an American citizen who has the right to be elected president of the United States.

In the previous life, the two of them were unhappy because of this matter, and Qiao Tianyu hadn't contacted him for several years, but he didn't expect that in this life, Li Jiaxing still took this step.

No! Qiao Tianyu was still angry when he heard the news!

Just take advantage of today's opportunity to educate this buddy well, and you must let him know what national honor is above all else!

Of course, it is also to earn back face for my great China......
