Hello 1983

Being gagged by them, the sadness of parting in Xu Changsheng's heart was also diluted a lot.

He picked up the wine glass: "Brothers, grandparents at home, please."

He had planned to study abroad a long time ago, but he just adhered to an old saying: if your parents are with you, you will not travel far.

In the past two years, I saw that my grandparents had a stable life and a healthy body, so I applied for studying abroad.

Most importantly, Xu Changsheng knew that the remaining three brothers had a prosperous career and were able to help him take care of the elderly.

As for how to repay, Xu Changsheng had already thought about it: after studying abroad, he would join Jade Bird.

"Don't worry, grandparents will definitely take care of you." Liu Qingshan patted Xu Changsheng on the shoulder and urged:

"When you get there, you don't need to do odd jobs, and you can spend your time and energy on your studies."

Well, Xu Changsheng nodded.

Liu Qingshan continued: "There is no need to save money, I have arranged everything for you, and there are scholarships over there."

He has already contacted Xiao Zihou, and anyone he doesn't know can help, let alone his brother.

Directly follow the maximum amount: [-] US dollars.

Coupled with Xu Changsheng's dividends from the company under the big tree, it has supported his study abroad life for several years, and there is no problem at all.

Xu Changsheng nodded emphatically again. He knew that this kind of friendship does not need to be expressed in words.

Liu Qingshan gave Xu Changsheng the addresses and contact numbers of his second sister and Qian Yuzhen, and the four brothers had a drink until very late before they dispersed.

As for the boss and the second child, they are quite comfortable working in the company under the big tree, and they don't want to study abroad at all.

The next day, Liu Qingshan asked Cao Xiaofei to drive him to the film and television city.

This distance is a bit far, so there is no need to ride a bicycle.

On the way, first go to Wapenyao Village to see Li Yifan's research situation.

Construction has started here, and the foundation is being dug. I have to thank First Young Master Li for getting this piece of land.

Thinking of First Young Master Li, Liu Qingshan couldn't help smacking his lips: I haven't seen you for a long time, I miss you so much.

First Young Master Li is a qualified money-giving little prince, and he is still very popular with Liu Qingshan.

Liu Qingshan reckoned that with the licentiousness of the Li family, they would definitely not give up, and would come to the capital to hoard land.

The private houses in Wapenyao Village are still preserved, and they are temporarily used as laboratories.

There were two veterans patrolling at the entrance of the village. When they saw Liu Qingshan, they immediately saluted.

After entering the village, Liu Qingshan saw that several houses were crumbling, and the roofs and windows were gone.

Liu Qingshan couldn't help being surprised: it couldn't be caused by the explosion, could it?

Just as he was thinking about it, he heard a muffled bang, smoke and dust billowed from a house by the road, and five or six people, rolling and crawling, rushed out from the door of the house.

In other rooms, people also ran out in a panic, yelling, "Is it exploding again?"

Liu Qingshan and Cao Xiaofei also ran over quickly. Fortunately, the few people who ran out from the explosion site were all in good shape.

Moreover, these people are also fully armed: steel helmets on their heads, tempered glass masks on their faces, and bulletproof vests on their bodies.

It is estimated that even if you charge on the battlefield, you will be able to advance despite the enemy's artillery fire.

These protective measures were also requested by Liu Qingshan, and he entrusted Xiao Wu and the others to get them from the army.

The men took off their helmets and masks, panting heavily.

Only then did Liu Qingshan see clearly that one of them was Li Yifan, who was still smiling at Liu Qingshan with bared teeth.

The other one is in his fifties, Liu Qingshan doesn't know him, and the other two are young people, probably students.

"Mr. Liu is here, it's all right, we are all veterans who have passed the test." Li Yifan was still joking.

Lithium is a metal, because its state is very unstable, so it is quite a dangerous experiment to study lithium batteries.

Immediately, Li Yifan introduced to Liu Qingshan: "Mr. Liu, this is Professor Gao from Huaqing, an expert in battery research."

This time Liu Qingshan was a bit unexpected, the two schools were in a competitive relationship, unexpectedly there was a professor willing to help there.

But then he was relieved: the competition between the two schools is a healthy competition, not the kind of stumbling behind the back, and of course there is some cooperation.

"Professor Gao, you are welcome to join, thank you for your hard work." Liu Qingshan hurried up to say hello, such a dangerous job is really not easy.

Professor Gao's face is thin, but his eyes are very lively. He waved his hand: "It's nothing, Nobel's research on explosives was much more dangerous than this."

After finishing speaking, he added with a smile: "And you Jade Bird's salary is so high, we must be worthy of those bonuses."

Liu Qingshan couldn't help feeling a warm current in his heart: the scientific and technological workers at this time are so respectable and lovely.

Chapter 763 This is a great idea

The laboratory where the accident happened just now is obviously unusable, and the window glass is shattered.

Anyway, these houses will be demolished in the end, and there is no need to repair them.

Li Yifan, Professor Gao and others went to change and wash first, and then met Liu Qingshan in a private house.

"Lithium is too unstable, like a irascible kid who changes his face when he says he will."

Li Yifan complained, and then waved his fist: "But we are confident that we will make it a good baby."

Of course Liu Qingshan is also confident, but in order to make research progress as soon as possible, he still took out a few pages and handed them to Li Yifan:

"This is the material purchased from a foreign laboratory through a special relationship. You can refer to it."

In fact, Liu Qingshan sorted out this thing himself, but he didn't explain the origin clearly, so he had to install it in a foreign laboratory first.

Hearing what he said, the people in the lithium battery research and development team immediately became serious.

"Is it Goodenough's laboratory, or Sony's?"

Li Yifan asked Liu Qingshan with a smile while picking up a document.

Goodenough, later known as the father of lithium batteries, won the Nobel Prize for this achievement decades later.

In terms of research on lithium batteries, the island country is currently in the leading position in the world.

Around 2000, they once monopolized the international lithium battery market, accounting for more than 90.00% of the market share.

That's why Li Yifan thought of these two places first.

Liu Qingshan just smiled: "You eat eggs every day, don't you have to know the hen that lays eggs?"

After finishing speaking, Li Yifan did not respond, because this guy had already buried his head in the information and read it.

The materials Liu Qingshan sorted out were not many, they were all dry goods, so Li Yifan quickly read them all.

Professor Gao next to him was about to take it over to take a look, but Li Yifan continued to read it from the beginning.

"Lithium-ion batteries, embedding lithium ions in carbon as the negative electrode, well, this is a great idea."

"The positive electrode can use LixCoO2, LixNiO2 or LixMnO4, wow. I didn't think of it!"

"The electrolyte uses LiPF6 + divinyl carbonate + dimethyl carbonate, haha, wonderful, wonderful!"

Looking at a good person, he was stimulated to become a cat.

Professor Gao was also emotional when he heard that: After solving the positive and negative electrode materials and electrolyte, a battery is basically 90.00% complete.

Judging from his professional ability and the accumulation of research in the past few months, these are very likely to be the correct way.

For the rest, they only need to use experiments to verify them one by one, without having to make detours.

This feeling is like being trapped in a maze. Suddenly, a road leading to the end appears under your feet.

That feeling made both Li Yifan and Professor Gao jump up from their chairs, shouting, "Prepare for a new experiment right now!"

Then he led the experimental team and rushed out of the room. In the blink of an eye, only Liu Qingshan and Cao Xiaofei were left in the room.

"Boss, what shall we do?" Cao Xiaofei looked at Liu Qingshan.

Liu Qingshan also shook his head helplessly: "It seems that we are not needed here, right?"

The two stood up and were about to leave, but they almost bumped into Li Yifan who was running back at the door.

Liu Qingshan supported the other party with his hands, and Li Yifan said excitedly:

"Boss, this information is too precious, don't worry, boss, we will definitely be able to produce the best lithium battery!"

After shaking Liu Qingshan's hand, Li Yifan turned around and left again, shaking his head as he walked, as happy as a child.

Li Yifan didn't ask any more questions. No laboratory would sell such precious information.

Because once it is successfully developed, this small battery can apply for more than a dozen patents, which means a steady stream of wealth.

And it also has an extremely bright prospect, and small lithium batteries can be applied to mobile phones or other small electronic devices.

But for the large ones, will they be used in motorcycles, automobiles, and in the field of national defense and military industry in the future?

Until many years later, no one mentioned the origin of this information.

Liu Qingshan left Wapenyao Village and continued to move forward. Through the car window, he could see that the main project of the Asian Games Village in the distance has been completed, and the next step of decoration and construction has been gradually started.

In more than a year, the Asian Games will begin.

Soon we arrived at the film and television city. During the Spring Festival, there were quite a lot of tourists who came to stroll around. There were actually a lot of tourists on the antique small street.

The most prosperous business, besides selling food, is taking pictures.

At this time, there are very few people who have their own cameras after all, so there are special photographers in general scenic spots, including the side of the square.

At first, the mailing address was left, and after the photos were developed, they were mailed according to the address.

Some state-run photo studios set up photo booths on the other side of the square, and there was a long row of people queuing up to take pictures.

At first it was a black and white photo, which was cheaper, nearly [-] yuan, which is basically a worker's day's wages, but it still couldn't stop the enthusiasm of the masses.

Because in the eyes of Chinese people, this is not only a building, but also represents the heart of the motherland.

In the early 80s, when I had a color photo, it cost one yuan and nine cents a piece.

The speed of developing photos has also been greatly accelerated, and the color photos can be developed in two or three hours, so that there is no need to post them.

In a few hours, the tourists came back from a stroll and just took photos.

There is also a photo studio in the current film and television city, and of course it is run by Longteng Company.

This is a unique business, and outsiders will not let it come if they want to.

Not only the photo studio, but also all the stalls operating on the ancient street. The practitioners are employees of Longteng Company, leading the nearby villagers.

Otherwise, how could there be so many people in the film and television city?

As the reputation of the film and television city spread in the capital, the number of tourists increased sharply. Every month, the income from these peripherals was more profitable than renting out the film and television city.

The change is put together to make up the whole money, and when it is really put together, it is actually not a lot at all.

During the Spring Festival, the ancient street is equivalent to a temple fair. Liu Qingshan strolled around and bought some children's playthings, such as cloth tigers, clay figurines, rattles, etc., and gave them to Xiao Lao Si and Xiao Huo Yueyue them.

Even the few temples and Taoist temples that have moved over in the film and television city are full of incense.

With the deepening of reform and opening in the past two years, these things are no longer prohibited.

After shopping around, Liu Qingshan went to find Wang Zhan after gaining a lot.

Entering Wang Zhan's office, it turned out to be an ancient yamen, Liu Qingshan shook the rattle in his hand:

"Master Qingtian, Wang Qingtian, you have to decide for me..."

Cao Xiaofei next to him covered his mouth and laughed straight away: If the boss is not serious, he is quite good at playing.

Wang Zhan poked his head out from a side room, looked at the situation, and yelled, "Come on, beat this complainant out with a stick!"

After finishing speaking, I burst out laughing: "Come in, Master Qingtian will make the decision for you."

After entering the room, Liu Qingshan discovered that there were guests, two middle-aged men, sitting at a table drinking tea.

Wang Zhan said quickly: "Let me introduce, this is Mr. Liu from Longteng, and these two are Director Liang and Comrade Zhang from the Asian Games Organizing Committee."

Liu Qingshan stopped joking and shook hands with the other party.

After sitting down again, we chatted for a few words. Deputy Director Liang was very talkative, saying that he had contact with Liu Qingshan when the house was being demolished.

And for the film and television city, they praised it for a while, saying that the ancient buildings are well protected, and those ancient trees are also well utilized.

In contrast, the Asian Games Village is a little bit worse. Although everything is new, but because it is so new, it seems to lack foundation.
