It was 9 a.m. when we arrived at Boston's Logan Airport, and after a long night's sleep, it was obvious that everyone was a little uncomfortable with the jet lag. Pen, fun, and www.biquge.info

But all of this was washed away by the excitement of going abroad.

Although it is not the first time to participate in an international competition, Chen Peipei and Cheng Ziang are still full of excitement, taking photos, recording videos, and having fun.

When everyone arrived downstairs at the airport, the shuttle bus from Harvard University in the United States had stopped there, which was also a small surprise.

Speaking of Harvard, this university represents a strong foundation and strong strength, not only in the United States, but also in the world.

Nearly all of the revolutionary pioneers since the American Revolution came from her disciples, and she is known as the think tank of the American government. It has produced eight U.S. presidents, 40 Nobel laureates and 30 Pulitzer Prize winners.

Her every move determines the direction of social development and economy in the United States, and the business school is well-known for her case teaching. Cultivated Microsoft, the creator of IBM's business miracles.

Her Yenching Institute is dedicated to the exchange of Chinese and American cultures, Dr. Kissinger, who communicated the relationship between China and the United States, and Lin Yutang, Zhu Kezhen, Liang Shiqiu, and Liang Sicheng, who laid the foundation of modern Chinese humanities and natural sciences, all of which are closely related to the world's most famous institution of higher learning.

Nearly every class of Harvard graduates eventually becomes the mainstay of America's elite society, and they also become leaders in various industries...

Jiang Yin is very curious about everything in the United States, looking at the street scenery that is slightly different from China, listening to Chen Peipei and Cheng Ziang's experience in coming to the United States, he greedily absorbs all the knowledge he can receive.

This US imperialist country, which was called a few decades ago that must be defeated, has now reached a delicate balance with China, and although the game between countries continues, the general direction of peace will not change, which also makes the United States a country that can now be visited by Chinese.

Harvard University is not very far from the airport, and it only takes about half an hour to drive there.

When the car slowly drove into the gate of Harvard University, Jiang Yin was stunned by this stingy gate, in Jiang Yin's imagination, the gate of this world-famous university must be quite magnificent, at least it can reflect a strong tolerance and determination to look at the world.

But a car passes through a somewhat narrow gate, which is actually the gate of Harvard?

"How? Be surprised, this is the legendary main gate of Harvard University, Johnston Gate, Harvard's main gate, built in 1889, is the oldest of all school gates, and it is opposite the famous First Unitarian Church. Chen Peipei began to show her senior sister's experience at this moment, and she gushed to Jiang Yin about the school gate she had just passed.

"Is this really the main gate of Harvard University?" The muscles at the corners of Jiang Yin's mouth trembled, he still couldn't believe that such a small door was a century-old gate.

Indeed, Harvard has a total of 24 gates, this gate is indeed the oldest, it uses special wrought iron techniques, and in addition to wrought iron, this door also uses a large number of bricks salvaged from the Harvard fire in 1764, their unique texture, color and structure make it famous in the construction industry, known as "Harvard wet mold bricks", which have been widely used in various Harvard buildings in the future. As the first example of Harvard architecture during the Colonial Revival, the architectural style of this door also became the architectural standard of Harvard in the late 19th and early 20th centuries. Cheng Ziang, known as a humanoid endorsement machine, continues to show the strength of his endorsement.

Jiang Yin turned his head, looked at the shabby main entrance that had gradually disappeared behind the seat, and shook his head, long-established universities like to make such a tune of memory.

Fortunately, Harvard did not make all the buildings in the ancient style, and the buildings that combined modern and historical gradually appeared on both sides of the road, and Jiang Yin also saw many young American students with blond hair and blue eyes reading and strolling on the streets, on the grass, and in the woods, and this atmosphere is very similar to that of BGI.

After a few turns, the car finally stopped in front of an old building, and when the interpreter told everyone that they had arrived, several people opened the door and got out of the car.

After getting out of the car, Jiang Yin raised his head and carefully looked at the building in front of him, this is a traditional Gothic building, the ceiling-style spire is very eye-catching, and there are many exquisite carvings on the windows and walls, but due to the erosion of the years, many of the carvings are slightly damaged, showing a sense of heaviness that has been baptized by history.

"This is the department building of the Department of Mathematics at Harvard in the United States, let's go~" Chen Peipei couldn't wait to lead the way to the first step up.

Translators, logistics, as well as Professor Jiang Fang, Jiang Yin and others also followed, pushing open the delicate wooden door, and the building exuded a faint fragrance of ink and books, making people feel as if they were in a sea of books for a moment.

However, Jiang Yin didn't like this taste very much, he always felt that there were some harmful substances in this taste.

But the others apparently didn't think the same way as him, and everyone sniffed with their noses, revealing a look of intoxication.

"Mr. Jiang!" Just as everyone was standing in the doorway, a deep male voice came from the left side of the hallway.

Jiang Yin also turned his head with the others, and saw an old American man with white hair and full of energy waving his arms at everyone.

"Oh! It's David! Jiang Fang's face was full of surprise for a moment, "David, hello!" Long time no see! (English)"

Jiang Yin turned his head to look at Professor Jiang Fang, he really didn't expect that this old professor could actually speak English.

"It's been a long time, the last time we met, it was at the International Mathematical Conference! The old man from the United States also walked over excitedly, and then shook hands warmly with Jiang Fang.

"Yes! After that, we haven't seen each other, and I haven't corresponded with you again, how are you doing? Jiang Fang asked with a smile.

"I'm fine, but now I spend most of my time teaching students, and I don't have much energy to study higher-level mathematical theories." The white-haired old man said with some regret.

"I'm the same, let's work together to cultivate talents for the future of the mathematical community, which is also a responsibility!" Jiang Fang smiled and said: "By the way, I haven't introduced you yet, these are my students, they are here to participate in the Mathematics Olympiad this time." Then he turned around, pointed at the white-haired old man with his palm, and said, "This is Mr. David Pisger, who is currently a professor in the Department of Mathematics at Harvard in the United States." ”

"Hello Professor." Chen Peipei and others were very honored to shake hands with this old American professor.

After shaking hands, the old professor seemed to be in a very good mood, he warmly entertained everyone, and then instructed the person in charge of the reception in the mathematics department to settle the place where Jiang Yin lived.

As the saying goes, acquaintances are easy to do, and this matter is a common principle all over the world, Jiang Yin and the others were arranged to stay in the hotel without waiting.....
