The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 280, The Invisible Hand
February 10, 1985, the 21st day of the twelfth lunar month.

Despite the assistance of the affiliated hospital's president and doctors such as Shi Ningquan, they were still unable to save Lu Jiaxi's life, and he passed away.

When the operating room doors were pushed open, Wang Duoyu could already tell the outcome from the expression on the face of the affiliated hospital's director.

Moreover, the sound of Zhang Shuqin wailing could be heard from inside the operating room, which undoubtedly confirmed this point.

Although it's unacceptable, what can be done now that things have come to this?
In fact, Wang Duoyu should also be grateful, because because of his intervention, Lu Jiaxi lived for at least one year and four months longer. Old Lu made a huge profit.

But some things are truly destined by fate.

Everyone's lifestyle habits, diet, and daily routines are already largely set.

If intervention can be carried out early, frankly speaking, living a few more years is entirely possible.

However, Lu Jiaxi believed that "ten thousand years is too long, seize the day," and he adhered to this idea for many years.

It was as if a ghost was really chasing him, making him dare not stop for even a moment.

It should be noted that, due to Wang Duoyu's intervention, he arrived at Harbin Institute of Technology early on, and he rarely had teaching duties; even when he did, they were relatively light.

His wife, Zhang Shuqin, had also been trying to persuade him.

However, he seemed not to hear and continued to do as he pleased.

"Professor Wang, I'm sorry, we did our best."

Upon hearing the words of the affiliated hospital's director, Wang Duoyu nodded silently.

Doctors aren't gods either; heart disease is something else entirely!

"You have worked hard!"

At this moment, Liu Deben and the others finally arrived.

Lu Jiaxi is a professor in the Department of Mathematics at Harbin Institute of Technology. Although he started as a teacher, he quickly became a professor at Harbin Institute of Technology after his papers were published one after another.

He was able to communicate with people like John Milnor, and subsequently published many more papers.

Lu Jiaxi holds a fairly high position among the leadership of Harbin Institute of Technology, and this is partly due to Wang Duoyu's particular attention to him.

Despite the abundance of talent in the Mathematics Department of Harbin Institute of Technology today, it seems that apart from Wang Duoyu, there are very few other talented individuals who can truly hold their own.

Yang Nianzhen, Rong Guangxia, and Gao Huajian are all quite skilled, but they can only be considered first-rate experts.

If John Milnor, Shing-Tung Yau, and others are considered top-tier masters, then Wiles, Aranconne, Jean-Baptiste, and others are in the second tier. Lu Jiaxi falls somewhere between this second tier and the top masters.

Yang Nianzhen, Yorkz, and the like are at the bottom of the first-class masters.

Although they are all top-notch players, there are still differences between them.

Therefore, this is one of the reasons why Liu Deben kept urging Wang Duoyu to recruit as many talented people as possible.

Liu Deben, Lü Gongliang, Han Jue and the others arrived, and upon learning that Lu Jiaxi had already left, they all wore expressions of deep sorrow.

The mathematics department already had very few Chinese mathematicians, and now that Lu Jiaxi has left, well, there's almost no core talent left.

Wu Congxin and the others are no good; they're just there to make up the numbers.

Shing-Tung Yau is an American and hasn't changed his nationality yet.

Even though people like Shing-Tung Yau work at Harbin Institute of Technology or the Harbin Institute of Technology for Advanced Study, their status is still different.

In October 1983, Hua Luogeng accepted an invitation from Caltech to conduct a year-long lecture tour there.

This is just exchange and learning, it's perfectly normal.

Ugh!
It’s difficult!
Wang Duoyu spent half a day at the affiliated hospital. Zhang Shuqin and her two children cried very sadly, which made Wang Duoyu feel quite distressed.

It's true that people who want to live long lives, leave a lasting mark on history, and have a wonderful life are overthinking things.

Not everyone is like Soong Mei-ling, able to live such a long life.

Soong Mei-ling, this great beauty, was born in 1897 and lived to 2003, a full 106 years old.

She was diagnosed with cancer twice during that period, but because it was detected early and treated in time, she was able to avoid it.

Regardless of Soong Mei-ling's own stance, she certainly lived a remarkable and long life.

She outlived several of her children, including her son and grandson, and grew old and frail, but she still lived a good life.

To be honest, Wang Duoyu just hoped to live as long and healthy as Soong Mei-ling.

On the night of Lu Jiaxi's funeral, heavy snow fell in Harbin, but by daytime, the sky was clear and blue.

After attending Lu Jiaxi's funeral, Wang Duoyu took Liu Xiaoli and the others to her parents' home.

Liu Zhensheng and Meng Pinggu were very happy to see Wang Duoyu come to visit them.

The happiest people were actually the two little ones, Wang Junhong and Wang Junan, because they received a warm welcome from their maternal grandparents.

Meng Pinggu and the others did not treat Wang Junhong differently because he was not Liu Xiaoli's biological son.

Even Liu Xiaoli herself tries her best to treat everyone equally. Even if Meng Pinggu and the others don't care about Wang Duoyu, they will still try their best to treat everyone equally for their daughter's sake.

Besides, Wang Duoyu is too smart, and Wang Junhong is also very smart. If the little guy senses this, he will probably talk about it to his father when he gets back.

Children are very sensitive, and Meng Pinggu and the others must know this, so they dare not treat them differently.

After spending most of the day at Liu's house and having dinner, Wang Duoyu and his friends returned to Harbin Institute of Technology.

When they got home, Wang Meili and the others had already returned from Tokyo.

After returning this time, they will have to wait until after the New Year to go there again.

Inside the study, Wang Duoyu sat down and chatted with Wang Meili, Wang Meihe, Lu Qingsong, and Li Yuanchao. Liu Xiaoli listened in but didn't interrupt.

As for Wang Junhong and his four children, they were already asleep.

“You’ve been in Tokyo for half a month now, let’s chat. What do you know, and what have you seen? Meili, you go first.”

Wang Meili, whose name was called, let out an "ah," though she was not very willing, but she had no choice but to speak first.

Tokyo is a large city with a thriving economy.

After 1945, they experienced several years of economic depression.

But the unexpected outbreak of the Korean War in the early 1950s gave Tokyo a tremendous opportunity, and immense wealth was thus acquired.

They already had a strong industrial base, and the workers' skills were largely intact, so they rose rapidly after the 1950s.

After a golden decade of development in the 1960s, it grew even more rapidly in the 1970s, and by 1972, it had become the world's second largest economy.

And from then on, it was never caught up by Germany again. In fact, the GDP gap between Japan and Germany widened, and Japan caught up very closely with the United States.

In 1985, Japan was at its zenith, with its economy booming.

It scared even the Americans.

So when Wang Meili and her group went to Tokyo, they saw a very rapidly developing, modern city.

Although Harbin is developing rapidly, it still lags behind Tokyo by the level of New York in terms of urban construction and other aspects.

For example, asphalt roads are only seen on a few main roads, while many other places are dirt or sand roads, and even cement roads have not been fully paved yet.

There are not many bus routes, and there are no subway lines at all.

There are public restrooms, but the hygiene conditions inside are... well, let's just say they're not great.

Previously, Wang Duoyu donated ten million US dollars to the Harbin city government. I wonder if Zhao Guobin will use it to improve these aspects?
Because Zhao Guobin would definitely not let the municipal government spend this ten million US dollars, but would instead entrust it to other institutions that need foreign exchange to spend the money, and then the municipal government would exchange it for other goods, RMB, etc.

After all, exchanging ten million US dollars in this way can bring back at least fifty million RMB, or even more valuable goods and materials.

Wang Meili has lived in Harbin for several years and knows the city very well.

I've also spent over half a month in Tokyo, so I'm very familiar with the differences between the two cities.

Of course, this was not the information Wang Duoyu wanted to hear. He needed his younger sister to have a clearer understanding of Tokyo's current real estate market, stock market conditions, and so on.

This point was added by Wang Meihe.

The current Tokyo real estate market looks very good.

According to information she gleaned from Zheng Baoyin and other senior executives at Yuma Garment Factory, Tokyo housing prices have risen somewhat in the past few years, but the actual growth rate has been average.

At most, it only increased by a little over one percent, which isn't much.

Japan's GDP was US$1.27 trillion in 1983, and its GDP last year was US$1.36 trillion.

In the original timeline, Japan's GDP in 1984 was 1.35 trillion US dollars, but in this timeline, things are somewhat different.

The reason why it has grown so much compared to the original timeline is due to the influence of companies affiliated with Harbin Institute of Technology.

First, there's the gaming industry. The entire market has actually seen a significant amount of profit siphoned off by Dolphin Games. Products like the Pet Egg game console and handheld game consoles have rapidly emerged, making Japan's gaming industry develop even faster than in the original timeline.

If these profits are all taken by Dolphin Games, then it's safe to say that Japan's GDP will only decline, not rise.

In reality, these profits were either converted into grain, high-end machine tools and other equipment, advanced technology and other goods, and then transported away through Lotte Group's ocean shipping companies, or invested in Lotte Group's real estate or financial companies.

Therefore, these funds never left Japan.

Secondly, the profits from other products such as PHS phones, Nebula supercomputers, and electric bicycles in Japan are similar.

These effects are actually very minor. Overall, they only increased Japan's GDP by a few billion US dollars, less than 10 billion US dollars. However, this amount of money just happened to increase Japan's GDP from 1.3596 trillion US dollars to 1.3601 trillion US dollars.

There is an impact, but not much.

Of course, whether it's 1.35 trillion or 1.36 trillion, the difference isn't that significant.

Compared to the US GDP of 4.04 trillion US dollars, the gap is not that big.

Back in 1983, the United States had $3.63 trillion, while Japan had $1.27 trillion, which naturally startled the United States.

As can be seen from Japan's GDP, the growth rate of Japan's real estate market is very low.

"So, Ninth Brother, I don't quite understand, will the Tokyo real estate market really rise after this year?"

Hearing his sister's question, Wang Duoyu smiled and nodded:

"Old Eleven, you don't need to ask any more questions. It's bound to go up. I've talked to you guys before about how the US uses financial means to exploit the world, and about the Bretton Woods system, etc."

"Furthermore, I've encouraged you to read more of the book 'The Rise of Great Powers.' You're certainly familiar with these financial theories, so under the current economic circumstances, the only way for the United States to improve the competitiveness of its exports in the international market is to devalue the dollar."

Just then, Lu Qingsong suddenly asked:

"Ninth Brother, what if, I mean, if the US didn't force the dollar to depreciate, or if they didn't force Japan to sell off its dollar reserves and assets to depreciate the dollar, then what about us?"

Wouldn't that be a waste of effort?
After all, there are many other methods besides devaluing the dollar.

For example, there are many methods, such as raising tariffs on imported products, government subsidies, lowering corporate loan interest rates, and reducing production and manufacturing costs, and they are not limited to the devaluation of the US dollar.

If it were really that easy to predict, wouldn't many people be able to anticipate a rise in Japanese real estate and stock prices, then chase the rise and sell the fall, profit from the price difference, and quickly cash out and leave the market?
Of course, it's not that easy to guess.

The reason why Liu Deben and his group, as well as Fang Lihe and others, had so many concerns and repeatedly advised Wang Duoyu not to place all his bets on the Tokyo real estate and stock markets was based on these reasons.

Wang Duoyu heard this and said with a smile:

"Xiao Lu, that's an excellent question. This isn't just a question you're wondering about; many people, even financial experts in Beijing and economics professors at Peking University, can't figure it out either: why is the US dollar depreciating?"

"I can only say that you don't understand the role of the US dollar in global economic activity; it's far more important than we imagine."

In his previous life, before Wang Duoyu transmigrated, the US dollar was still the world's strongest currency, and many people still chose the US dollar as the transaction currency when conducting international trade.

No matter how powerful the euro is, or how strong the renminbi and other currencies are, the US dollar is still the most powerful global economic transaction currency, bar none.

With the US dollar being so powerful, of course the US should choose to depreciate its dollar to enhance the competitiveness of its export products.

In addition, it is also closely related to the historical context.

After the end of the gold standard, the Bretton Woods system, and the Smithsonian Agreement, the foreign exchange market developed into a completely unregulated market, with only the "invisible hand" of the free capital market striving to establish economic balance through supply and demand.

Unfortunately, a series of unexpected economic events, such as the oil crisis encountered by OPEC, the stagflation that lasted throughout the 1970s, and the dramatic changes in the Federal Reserve's fiscal policy, made it clear that relying solely on supply and demand was no longer sufficient to regulate the foreign exchange market.

The entire foreign exchange market continues to establish a system that is not rigid but also flexible.

Because the Bretton Woods system proved that linking the value of currency to commodities like gold was too rigid and detrimental to economic development.

The same applies to limiting the maximum fluctuation range of exchange rates.

Therefore, for the past half-century, the foreign exchange market has been struggling with the relationship between regulation and rigidity.

At this time, the Plaza Accord came into being.

The reason for allowing the dollar to depreciate, rather than raising tariffs or using other methods to regulate the foreign exchange market, thereby promoting rapid global economic growth and reducing inflation rates in various countries, is that depreciating the dollar is the best solution.

If the US raises tariffs on imported products, other countries like Japan could do the same.

This tactic harms others without benefiting oneself.

Besides, the great wave of globalization was originally driven by the United States behind the scenes, so why would they voluntarily close this door?

If they were to raise tariffs, well, that would contradict their strategy.

In the past few years, since Reagan took office, he has implemented economic policies such as high interest rates, which have caused the dollar to appreciate sharply against major currencies, having a very negative impact on the US economy, especially manufacturing and exports.

As a result, the United States has a huge and ever-growing current account deficit, while Japan and Germany have huge and ever-growing trade surpluses.

Such imbalances can lead to severe economic imbalances, which in turn distort the foreign exchange market and the international economy.

The United States recognized that the rapid appreciation of the dollar over the past few years—more than 80 percent—was the main culprit, leading to the huge trade deficit.

Therefore, the United States can only use the method of devaluing the dollar to balance the import and export capabilities of all countries, thereby helping to stabilize the international economy.

That's the main reason.

However, Lu Qingsong and the others found it hard to believe Wang Duoyu's judgment, simply because they lacked the level of understanding to determine whether the matter was true or not.

Wang Duoyu only gave a rough explanation of the reasons and historical context, but Lu Qingsong and Wang Meili were still skeptical, and there was nothing he could do.

Everyone's level of understanding is different. Even intellectuals like Fang Lihe and Liu Deben were limited by their times and could not have such strategic vision, let alone Lu Qingsong and others.

Is there any specialization in the art industry?

Whether Lu Qingsong and the others believe it or not doesn't matter; they just need to carry out Wang Duoyu's orders properly.

That night, Wang Duoyu and his friends chatted until 11:30 p.m., about an hour later than usual before going to bed.

The next day, Wang Duoyu and his group set off back to Dahonggou Village.

Wang Meili and her family did not return with them. Instead, they took a plane back to Lu Qingsong and Li Yuanchao's hometown.

Dahonggou Village, the wooden house at the end of the village.

After the wolfhounds returned to the village, they began to plan out their own territory.

Little Wang Junhong, dressed in chubby clothes, ran all over the village.

His younger brother, Wang Jun'an, was too young to come along; instead, he stayed home to play.

The ancestral home of the Wang family is packed with people today, all of them relatives of the Wang family.

Whether they worked at Want Want Group or at nearby farms, they all came back.

Today is the 28th day of the Lunar New Year, and everyone is no longer busy.

Everyone gathered at Old Wang's ancestral home to chat, warming themselves by the fire, eating sunflower seeds, and idly talking.

There is heating inside, but it's not as warm as in the city because it's close to the mountains and the temperature drops quickly, so you still need to use a fire to warm yourself indoors.

After his fall before the Lunar New Year, Wang Shoucheng had just returned from the capital and was now being watched over 24 hours a day. The whole family sat in the same room chatting, making a lively scene. No one found it noisy; on the contrary, they enjoyed this rare moment of warmth.

Because moments like these are so rare.

As they chatted, Wang Duoyu's third brother took the initiative to bring up the topic of highway construction.

The main reason is that in the past year, several villages near Dahonggou Village have been developing the livestock industry, and such an economy is particularly dependent on transportation.

At the same time, with more money in their pockets, people's demands in various aspects have also increased significantly.

For example, people used to really not care what happened to that muddy road; they didn't think much of it at all.

Because everyone is poor, we just need these dirt mountain roads; why should we have so many other things to strive for?

But things are different now.

Even Wang Duozhi had been to Harbin several times, and he was particularly envious of the main roads, which were asphalt roads.

"The leaders of Shuanghe County are thinking about whether they can talk to the people of Bingcheng to revitalize the current road and turn it from a sand and gravel road into a cement road."

"In addition, Duoyu, the villagers from our Dahonggou Village, as well as several nearby villages, are all willing to contribute their efforts. We'll help out for free when the road is being repaired."

"Also, our Wang family has indeed made a fortune in recent years. There's an old saying that goes, 'When you're successful, you should help others.'"

"Third Brother might be wrong. You may have your own ideas. I was just saying."

"However, I hope you can consider these words."

Wealth and honor do not return to their hometown, just like walking in brocade at night.

Wang Duoyu was certainly not hiding his talents in secret; he had helped Shuanghe County before, and he was the one who proposed the idea of ​​developing the aquaculture industry.

After all, he advocates one point: it's better to teach a man to fish than to give him a fish!

But here in China, there are always one thing or another.

Everyone has their own ideas. For example, his third brother, Wang Duozhi, talked to Wang Duoyu about this.

He probably had his own selfish motives, after all, the Wang family is indeed doing well now.

If we can do our best to help our fellow villagers, that would be the icing on the cake.

Moreover, each household has indeed discussed it and agreed that if the road can be repaired, each household will send one person to help repair the road for free.

Even if the gravel road from Shuanghe County to Bingcheng is not repaired, the road from Dahonggou Village to Shuanghe County should be repaired and turned into a cement road.

This will make it more convenient for everyone to travel.

Wang Duoyu pondered for a moment, then remained silent.

Inside the house, everyone sat quietly. Even the noise of the little kids chasing and playing had decreased significantly, as they gradually quieted down after being quietly scolded or given a sharp look by their parents.

After a moment of contemplation, Wang Duoyu suddenly spoke:

"Third Brother, in principle I should support your decision, but not this year. We have to wait a little longer."

"The Want Want Group didn't make much money this year, and the money spent on road repairs will definitely be substantial."

"To be honest, I want this road repaired even more than you do. I've even thought about building a direct asphalt highway from the start."

Every year, Wang Duoyu would return to his hometown. It's a journey of over 400 kilometers from Harbin to Dahonggou Village. Doesn't he want to repair this road?

Of course I want to!

The problem is, thinking about it isn't enough; he also needs funding.

In this era, road construction costs are not so high, especially now that the road from Bingcheng to Shuanghe County has been straightened.

Once the cement, sand, and workers are in place, the road paving can basically begin.

However, the journey is over 400 kilometers long, with two lanes in each direction. The cost of cement, sand, and other materials required per kilometer is at least 300,000 RMB.

Even if the cement road is laid to the lowest standard, the cost per kilometer would be at least 100,000 RMB.

If you want to lay asphalt as well, the cost will be even higher.

So the workers helped pave the road for free, but the cost of materials for 400 kilometers of highway is at least 40 million RMB.

Based on Want Want Group's total revenue of 975 million RMB in China last year, even if the profit is only 300 million RMB, it should be enough to pay for the 40 million RMB cost of highway construction materials, right?

But the situation can't be calculated so simply.

What benefits will this road bring to Wang Duoyu and Want Want Group?

Is it just to make it more convenient for Wang Duoyu to go back to his hometown every time?

Or would it be more convenient for the Want Want Group's canteen purchasing department to come to Shuanghe County to buy poultry and livestock such as chickens, ducks, geese, beef, and mutton?
Certainly not!

We can't just ask Wang Duoyu to pay this money directly just because he's from Shuanghe County, can we?

If Want Want Group earns tens of billions, then donating 40 million RMB is certainly no big deal; it's just doing charity.

But what Wang Duoyu hopes for even more is that other organizations and individuals along the way will contribute money or effort as needed, rather than just taking advantage of Wang Duoyu alone.

Even if Want Want Group pays the majority, Wang Duoyu is happy to accept the smaller share from others.

The saying "If you want to get rich, build roads first" is absolutely true.

But whether it's Shuanghe County or other counties and cities along the way, I should at least say a few words.

Besides, it's inappropriate for Wang Duozhi to say these words; it feels like emotional blackmail.

Anyway, Wang Duoyu knew that his third brother had been used as a pawn.

However, Wang Duoyu couldn't just casually talk about doing good deeds.

In short, this matter can be done, but Wang Duoyu just wants to wait and see when it will be done.

When the time is right, someone will naturally bring it up.

Inside the ancestral home, everyone listened to Wang Duoyu's words and began to discuss and chat.

Wang Duoyu didn't mention anything more; in short, it was just a matter of 'waiting a bit'.

The next few days will be the Spring Festival.

Lunar New Year's Eve is February 19th, and Lunar New Year's Day is the 20th.

This year's Spring Festival was exceptionally late, but also exceptionally lively.

Many families in Dahonggou Village now own televisions, so everyone watches the Spring Festival Gala during holidays.

Unlike before, many villagers brought Wang Duoyu a lot of local specialties.

Although everyone knew that Wang Duoyu didn't lack these things, they still wanted to give them to him.

Because if it weren't for Wang Duoyu, they would never be living the good life they have now.

The mountain products they brought were either delicacies they had brought from the mountains themselves, such as animal hides, lingzhi mushrooms, and ginseng.

Or they would go to nearby villages to buy them.

After all, many villagers work for Want Want Group, and they don't have that much time and energy to go to the mountains to get so many mountain products.

Wang Duoyu didn't want these gifts, but he couldn't refuse them.

People drop off their gifts and run away as soon as they're done; you can't catch them.

Since it was a token of everyone's goodwill, Wang Duoyu accepted it with a smile and would deal with these things later.

Anyway, his family definitely can't finish eating or using all this stuff, because there's just too much.

I don't know if everyone is afraid that he will return to Harbin on the first day of the Lunar New Year, so the gifts are all delivered on the 29th day of the Lunar New Year or on New Year's Eve. In short, they are all delivered before the New Year.

This also meant that his wooden hut simply couldn't hold all his things.

"Perhaps I should build another house."

Looking at the gifts filling the yard, Wang Duoyu felt both amused and touched, and couldn't help but ponder.

Wooden houses age quickly. The wooden house in front of us was built in September 1979, which is more than five years ago.

Although it has only been a little over five years, the wind and sun have naturally made it much worse than before.

However, if we rebuild the house here in our hometown, we probably won't be able to build a wooden cabin again.

Because not many of Lao Wang's relatives remain in Dahonggou Village now, and those who do are mostly elderly and weak, it's impossible for him to have someone help him cut down trees and build a wooden house like he did five years ago.

But whatever, it's fine if it's not a wooden house. A reinforced concrete house is just as good, sturdy and durable.

On the fifth day of the Lunar New Year, Wang Duoyu's family set off to return to Harbin.

This Spring Festival, he spent a long time back in his hometown, partly to relax and partly to avoid Qiu Chengtong and Charles Feifman.

Before the New Year, they had been pressuring him to finish the proof of the reciprocity law conjecture paper as soon as possible, but he naturally tried to delay it as much as possible.

So he spent the Spring Festival in his hometown, which allowed him to completely relax.

People can't always be so tense, otherwise it's easy for something bad to happen.

Wang Duoyu wasn't one of those people who couldn't see the point in life; on the contrary, he found life incredibly interesting.

Honestly, he still can't understand those people who contemplate suicide. These people are exposed to too much negative information, which is why they have the courage to light a charcoal fire and end their lives.

There are so many meaningful things in life; fame and fortune are like fleeting clouds to me.
No, no, no, that's because these kinds of people have never experienced what fame and fortune are like, which is why they can say such things.

Despite suffering repeated setbacks and experiencing many ups and downs in his life, Li Bai still created many poems that have been passed down through the ages.

Of course, Li Bai lived to be 61 years old during the Tang Dynasty, which was considered a long life in that era. Therefore, Wang Duoyu did not really believe the story that he drowned while trying to catch the moon while drunk.

In short, life is a long journey with many different landscapes, people, and events. Those who attempt suicide are simply foolish.

People like Lu Jiaxi neglect their health in pursuit of mathematical truth, a practice that Wang Duoyu also disapproves of.

In his past life, he had seen too many of these kinds of people who were born to earn money but not to spend it. In particular, there were many researchers like this in scientific research institutes, and in the brightly lit office buildings of large factories in Beijing at three or four in the morning. Aren't those people just hardworking oxen and horses?

A balanced approach to life is the best attitude.

"Duoyu, what should we do with these gifts?"

I'm about to leave my hometown, but there are still a lot of mountain products sent by relatives, friends and neighbors to the wooden house. In addition to animal hides, ginseng, and lingzhi, there are also a lot of chickens, ducks and geese, as well as smoked bacon and sausages.

Piles piled up!

Liu Xiaoli had just finished speaking, and Wang Duoyu hadn't even opened his mouth yet, when the little brat Wang Junhong quickly stepped forward:

"Mom and Dad, can we take them all home? These sausages are especially delicious, and so are these animal hides."

This little kid, who's just over four years old, already knows how to distribute these things. He can even call out the names of the children of his neighbors in the Harbin Institute of Technology faculty villa area and tell them how to deliver them.

Hearing the little brat say that, Wang Duoyu remembered, "That's right, a return gift!"
He received a lot of gifts when he held full moon celebrations and birthday parties for Wang Junhong and Wang Junan.

Although some people have already returned the gifts, many others haven't, because the teachers at Harbin Institute of Technology don't seem to be very keen on having a wedding; they prefer to keep things simple.

This gift is very difficult to return.

Even those who returned the gifts, Wang Duoyu hardly ever attended them, because he simply didn't have that much time to deal with these trivial matters.

Take the Fields Medal as an example. After he won the award, he would have been invited to many similar events.

But Wang Duoyu refused to participate, rejecting almost all offers.

From the perspective of the original timeline, after receiving this major award, Shing-Tung Yau and his colleagues received numerous invitations and published very few papers in the year following the award.

Just like Smail, after winning the award, he became lost in the compliments of everyone around him and couldn't extricate himself.

But Wang Duoyu is not that kind of person. He feels that attending such gatherings, reports, and speeches is not very meaningful, so he almost never attends them.

Therefore, it would be good to return all these gifts during the Spring Festival.

Moreover, these are all mountain delicacies, perfect for returning gifts.

So, Wang Duoyu waved his hand and decided to load all these things onto the truck.

Upon hearing this, the little guy jumped up and down with joy, overjoyed.

Three cars were clearly not enough, so in the end, Wang Duoyu's convoy returned with six cars, one of which was driven by Wang Jianda, and it was a car from the Want Want Group.

After returning to Harbin Institute of Technology, Wang Duoyu began arranging return gifts, simply following the list of those who had given him gifts before.

As a result, on the sixth day of the Lunar New Year, Shing-Tung Yau, John Milnor, and others came to his house to inquire about his thesis.

"Holidays are for relaxation and fun, so who has time to work?"

Wang Duoyu argued vehemently:
"As you all know, I'm always very busy. You can't expect me to be as busy as an old dog during a holiday like Chinese New Year, can you? That would be going too far."

Shing-Tung Yau and others: "."

"Professor Wang, you said you would give it to us after the Spring Festival. Why don't you skip the inspection and let us do it?"

Charles Feifman spoke up, and everyone agreed with him, but Wang Duoyu refused.

"No way. I still have some pride. If my research results are flawed, I'd rather destroy them. I have to make sure that the research results are absolutely correct."

Seeing this, everyone had no choice but to urge them on again before leaving with their gifts.

Smail wanted to store Moutai liquor in his cellar, but unfortunately, he didn't have any!

Wang Duoyu values ​​the aged Moutai quite a bit. On the other hand, he believes that when it comes to alcohol, moderation is key, and there's no need to be so greedy.

In life, we still need to control our desires and not be too greedy. Obesity is not a symbol of wealth, but a disease.

Having narrowly escaped disaster, Wang Duoyu finally got back to work.

March has arrived in the blink of an eye, and on March 3rd, Harbin Institute of Technology started its new semester.

Actually, today is only the twelfth day of the first lunar month, and the Lantern Festival hasn't passed yet.

Unfortunately, this semester is destined to be shorter, after all, it's already March 3rd.

With the start of the new semester at Harbin Institute of Technology, the entire campus has become exceptionally lively once again.

But none of this seems to concern Wang Duoyu, because he has been working very hard lately and has completely ignored what's going on around him.

In the blink of an eye, the Lantern Festival has arrived.

Wang Duoyu took a break and relaxed for half a day. After eating glutinous rice balls, he returned to work the next day.

After several days of seclusion, on March 1st, he finally completed the proof of the infinite-dimensional partial differential equation.

What are infinite-dimensional partial differential equations?

For example, the fundamental equations of quantum mechanics proposed by the German physicist Erwin Schrödinger in 1925 are a set of infinite-dimensional partial differential equations, known as the Schrödinger equations.

The Schrödinger equation provides a complete description of relativity and quantum mechanics, combining physical quantities such as electromagnetic fields and their particles with quantum descriptions.

Its basic idea is to use quantum mechanics to describe all physical phenomena in the universe.

The infinite-dimensional partial differential equations derived by Wang Duoyu have wide applications in fields such as function analysis and functional analysis. To give a simple example...

In his previous life, Wang Duoyu worked at a research institute in Beijing that only had a numerical code name. He assisted in calculations for a Hammerstein model of a microcantilever beam distribution parameter system in atomic force microscopy.

This requires using an infinite-dimensional partial differential equation model of the system to transform the time domain into the form of ordinary differential equations. Since the controller design does not need to consider the effects of spatial coupling, it is necessary to establish a Hammerstein model of the system in the time domain for this transformation.

After completing the proof of the infinite-dimensional partial differential equation, Wang Duoyu breathed a sigh of relief. His next task was to improve the paper and then submit the previous proof of the reciprocity law conjecture to the editor-in-chief, Jean-Baptiste, for review.
