80s Returning Doctor

"Haha, you're being humble!" Minister Xu smiled.

Professor Han hurriedly said: "My student has only worked for a short time, and his experience is still a bit lacking. Please don't praise him so much. It would be bad if he becomes proud and complacent later on."

Minister Chen shook his head in disapproval, "Professor Han, what you said is wrong, you are a very good student, you have won awards at such a young age, you have participated in so many projects, and you are so humble, you still Afraid of complacency, I don't think you know how to cherish it!"

"Hahaha, thank you, thank you!" Professor Han smiled, and didn't say any more polite words, so as not to be thought to be a good boy because he got a cheap one.

As for He Jing, he just smiled and didn't interrupt, looking very obedient.

"Okay, don't say those polite words, let's get down to business quickly, Lao Xu, you were anxious to meet people before, don't waste time now." Minister Chen looked at his watch and hurriedly urged, for them For such a person, time is very precious, and these polite words are enough.

Minister Xu quickly nodded and agreed, "Yes, yes, it's important."

As he said that, he looked at He Jing seriously, "Dr. He, I came here this time to cooperate with your project team."

When He Jing heard the identity of this person, he understood the purpose of this person's coming. When he heard that he wanted to cooperate, He Jing listened carefully.

"I read the project approval report of the mobile phone project you submitted. Are you going to start developing mobile phones?"

He Jing nodded, "Yes, I'm already forming a project team. Once the project is approved, we will start the next work immediately."

Minister Xu laughed with satisfaction when he heard the answer, "Haha, that's good, are you interested in cooperating with our post and telecommunications department? To be honest, we also attach great importance to the development of mobile communications now, and there will be more in the next five years." We continue to build communication base stations, but the key is that we do not have our own products now, and the mobile communication equipment that is currently on the market is imported from abroad, and the price is very expensive.”

Speaking of this, Minister Xu sighed. It is very bad for this Minister Xu that the communication is in the hands of foreigners. After all, they cannot be sure of safety.

"To be honest, I have carefully read your project approval report, and I have had a special person review it. It is very feasible. I think there is a great chance of success. This is what we need."

Of course, they came to He Jing after careful consideration. Their post and telecommunications department naturally has their own research institutes, and they naturally want to do research on their own. Unfortunately, the technical ability is not enough after all, and there is also a lack of more advanced directions. This time, He Jing's research project For them, that was a big opportunity, so he took the initiative to find them.

The cooperation from the post and telecommunications department is an opportunity, and He Jing will not refuse, but He Jing will not easily agree to it before he knows the other party's cooperation plan.

He looked a little surprised, "Minister Xu, you think highly of me. To be honest, I'm not sure how high the success rate of this project is. After all, the key depends on the progress of chip research and development at the Semiconductor Research Institute. I can't even Guaranteed how fast this progress will be."

If you just want to make a mobile phone, it is of course easy, but it is not so easy to develop a mobile phone with excellent performance and small enough size. After all, chip research always takes time.If it goes well, it will take a year or two. If it doesn't go well, then maybe it will happen, maybe three or four years.

Minister Xu was not shocked by He Jing's words at all, but looked very confident, "I'm not worried about this. To be honest, I, Mr. Qi, is very confident, and I am also very confident in you. You are not that kind Someone who would stall his own research."

Before the cooperation, Minister Xu naturally investigated He Jing carefully, after all, this project is very important.Although He Jing has not worked for a long time, he has never been an aimless person, and he has made sufficient preparations before undertaking each project.Moreover, he also visited Qi Lao in advance, knowing that the research and development of the lithography machine is still very smooth, and the research of the chip will naturally go smoothly in the future.

Hearing this, he knew that Minister Xu was very sincere. He Jing had wanted to cooperate with them, so he felt much more at ease now.

However, he still said, "Minister Xu, my project hasn't been approved yet?"

Hearing this, Minister Xu immediately looked at Minister Chen, "Old Chen, what did you say?"

Minister Chen smiled helplessly, but still said to He Jing seriously: "The current project review has been completed, almost completed, and the documents will come down in two days, you can rest assured."

This is good news, and He Jing couldn't help getting excited, "Really, that's great!"

With this news, he can proceed to the next action.

Minister Xu also hurriedly urged, "How should I say it, it's about our cooperation."

He Jing did not shirk this time, "How do you want to cooperate?"

Minister Xu changed his posture and leaned slightly towards He Jing, "Look at this, the project is of course led by your side, and our side will send some researchers to help, and there is funding. We Will provide some...."

This cooperation is really sincere, money for money, people for people, and what the post and telecommunications department needs is the final research results and the right to produce mobile phones.

He Jing doesn't pay much attention to this. After all, even if he has developed a mobile phone, the patent ownership belongs to the laboratory and the country. The follow-up matters will naturally be handled by the school. He Jing doesn't have to worry about it. The most important thing is to It is the initiative of the project. Judging from the meaning of Minister Xu, they don't intend to interfere much, and they seem to have unexpected trust in He Jing.

He Jing had no reason not to agree, "Of course, it's still an advantage for me."

Minister Xu laughed, "No, no, you are doing more work for those who are capable, and you should be the one who suffers."

What they want most is the result. As for who researched it, that is not too important.

After agreeing on this matter, Minister Chen and Minister Xu didn't stay any longer. They also spared time deliberately, and they still have a lot of things to do afterwards.

Professor Han didn't intervene when they were talking, but just followed their conversation carefully, and was ready to help He Jing when he couldn't handle it.But what made him gratified was that He Jing handled it well and didn't need him to get involved, which made him very proud.

After sending the person downstairs, after a few polite words, the two ministers got into the car, and the car was quickly driven away.

Watching the car go away, Professor Han finally couldn't help laughing, the smile was so cheerful, he couldn't help looking at He Jing, and began to look carefully.

He Jing looked a little uncomfortable, and couldn't help asking, "Teacher, is there a problem?"

Professor Han shook his head, "No, how could there be a problem! I am so happy!"

"I didn't even think that you would be approached by someone looking for cooperation so quickly, and it's still a big unit like the Ministry of Posts and Telecommunications."

"Good, really good."

Professor Han is really very happy and very proud. After all, this is not something that ordinary people can do, and the project of He Jing's mobile phone has been approved. This is a great thing. To be honest, the current He Jing is better than He was much more powerful back then, and he was not inferior to his senior brother. Thinking about it, he was even happier, and wished he could find someone to have a few more drinks immediately.Thinking of this in his heart, he planned to call his senior brother later to see if he had time at night, and then the two of them could have a good talk.

He Jing didn't expect Professor Han to be so happy, but he was actually quite happy. After all, with the support of the post and telecommunications department, his research would go much smoother.

"I didn't expect them to come here, but that's good. I'm short of manpower for this research, so this can be regarded as a timely help."

Professor Han frowned when he heard that, "Oh, it's a matter of course. Most of the people in our laboratory are not suitable for your project. What do you plan to do?"

"I want to find the computer laboratory of Q University. Their strength is still very strong. They also need to transfer a few researchers related to materials, but this requires the help of the school."

Professor Han nodded, "There is no problem with this. Give me the list, and I will help you find someone. As for the computer laboratory, there is no problem. Your uncle has cooperation with the person in charge over there. Let him tell you." That's it."

Semiconductors have a lot to do with computers, so it's normal for Mr. Qi to be familiar with the person in charge there.

He Jing did not refuse Professor Han's offer of help. After all, they were part of his own resources. It was a good thing that he could achieve his goal as soon as possible, as long as the experiment was carried out in a down-to-earth manner.

He Jing handed over the list of required personnel to Professor Han, and the other party was very fast. Within a week, those people were picked up one after another. At this time, He Jing also received the documents for the approval of the mobile phone project, and the funds were also released. It was quickly put in place, including researchers and funds from the post and telecommunications office.

Now that everyone has arrived, He Jing can start the preparatory work. Of course, he didn't forget to pay attention to the progress of Qi Lao's chip.

The scientific and technological seminars are over, new scientific and technological development directions and policies have been determined one after another, chips and lithography machines have been listed as key development projects, and special funds have also been established. This is very good news for Qi Lao, at least not I am worried that I will face the situation of running out of funds before I have studied it for a long time.

The key to a mobile phone is the chip, and then the battery and software.There are people on the computer side of the software. As long as He Jing puts forward various requirements in detail, the people on the computer side will make corresponding things according to his requirements. What Jing He pays more attention to is lithium-ion batteries.

The person in charge of the material part is a very experienced professor at Q University who is very experienced in the research of lithium batteries. As for lithium-ion batteries, that is a new topic.

The professor's surname is Qian, and he is very interested in He Jing's project. This time, he took the initiative to come here. Originally, He Jing just wanted a few ordinary researchers. After all, he has already determined the research direction, and these people only need Just follow his experimental direction to experiment and find the most suitable polymer.

Professor Qian is very interested in He Jing's ideas. Of course, what he is most interested in is He Jing's way of thinking. How can he be sure that this is the direction of his research!So when he came here on the first day, he pulled He Jing and chatted non-stop, which made He Jing very helpless. He couldn't say that it was because he came from the future.

However, this Professor Qian is still very capable, and he works very hard. It didn't take long for the laboratory to make progress.

"Haha, yes, this lithium iron phosphate is very suitable. It can be used as the Huang Zuyao component of the polymer. Hurry up, try adding some other elements, and make a record..."

When He Jingcai entered the laboratory, he heard Professor Qian's excited voice. The research had progressed, and He Jing was also a little excited, so he quickly approached.

Over there, Professor Qian was staring intently at the experimental results of the test bench, surrounded by a circle of people.

"What's the situation? Has there been any progress?" He Jing asked someone casually.

"Yes, Team Leader He, preliminary progress has been made, and the cathode material can be regarded as a breakthrough." The man looked very excited.

At this moment, Professor Qian also heard He Jing's voice, and hurriedly called him over, "Group Leader He, hurry up and see something good."

"Here we come." He Jing was not polite, and quickly approached, and the group of people around quickly stepped aside, making room for He Jing to approach Professor Qian.

At this time, Professor Qian is testing the positive electrode data. Of course, it is only a simple element, not a polymer, but the above value is already very good.

The plan He Jing made before was to use phosphate materials, so they all experimented with the same type of materials, and it is normal to find this one that is more suitable.

Seeing Professor He Jingqian very happy, he chattered, "He Jing, the direction you mentioned is really good. The existing phosphate materials with olivine structure are very good, not only can withstand high temperature , and very safe. Of course, the most important thing is that it is cheap, almost a natural material. Of course, the more important thing is that it is light enough...."

Phosphate is generally used as a food additive. No one had thought of using this material to be conveniently applied to batteries before, so he was also very surprised by He Jing's idea before, and now he feels that He Jing is a genius.

He Jing is not surprised by this result. In the future, the development of lithium-ion batteries can be said to be advancing rapidly. From volume, capacity, safety, service life and environmental protection, breakthroughs are made almost every year.Now is just the beginning.

He Jing patiently listened to Professor Qian's experimental process, and from time to time, he would echo a few times, or casually put forward some ideas, trying to let the other party make new results as soon as possible.

After bidding farewell to Professor Qian He Jing, he went to visit several other groups and cared about their research progress.This time, the entire mobile phone research team was of course more than just a few people. There were about 30 people in total, and they were divided into several groups. Each group had its own tasks, and He Jing was in charge of these groups.There is less time to do experiments by yourself, and more time to manage various groups, propose ideas, and assign tasks to them to verify the possibility of their own ideas.

It seems to be a lot easier than before, but it is not. In fact, the workload is more. He needs to read a lot of materials every day. He still pays attention to the progress of the experiment, adjusts the direction at any time, and makes the most appropriate decision.

The New Year passed in such a busy way, but this time, He Jing didn't have so much time to visit everywhere. He only had a two-day break on New Year's Eve and New Year's Day, and then started working again.

He Jing, who is busy, has no mood to pay attention to the development of Jingyuan Technology.

After the [-]th, the sales of Jingyuan Technology's remote control cars began to cool down a lot. The purchasers of various partners reduced their purchases, and some even chose to stop cooperation.At first, He Shenghua and the others didn't take this matter to heart. After all, they spent a lot of money during the Chinese New Year. They bought everything that should be bought. It is normal for sales to decrease.

Unfortunately, things are not just that simple.

With a sound of "Bump!", the door of the office was pushed open from the outside and slammed heavily on the wall, and then He Shenghua rushed in angrily. I know this is very angry.

"What are you doing? Why are you so angry!" Jiang Ping was taken aback, feeling his heart was a little unstable, and there was some complaint in his tone.

"Our products have been stolen!" He Shenghua said these words almost through gritted teeth, in a tone of hatred.

His words made the people in the office couldn't help but look over, and their faces immediately became ugly. Of course, there are not many people in this office, only Jiang Ping and Lu Fusheng.

Lu Fusheng spoke first, "What's going on, please explain carefully."

Jiang Ping also quickly pulled the man over to sit down, and poured him a glass of water, "Yes, please tell me carefully."

He Shenghua poured a glass of water in one gulp, let himself calm down, and then slowly said: "Isn't the business not doing well recently, so I went shopping around to see what's going on now, but I found out that the market Many people on the Internet are selling remote-controlled cars, all of which are similar in shape, and they even put our name on them, saying that they are Jingyuan’s remote-controlled cars..."

He Shenghua was really very angry, even if it was fake, and still using the name of their factory, he almost couldn't help but stepped forward and overturned the stall, just because he wanted not to cause trouble, so he couldn't help it.After that, he looked around again, but he didn't expect that there were quite a few such people.

Lu Fusheng frowned, "Is their car exactly the same as ours?"

But He Shenghua shook his head, "It's the same, it's the same appearance, the car is just a little plastic with a few wheels, it's very rough, it's not good at all."

If they were exactly the same, he wouldn't be so angry, but their name is still used for such a bad thing, which is simply ruining the reputation of their factory.

Jiang Ping was relieved now, "That's okay, at least it proves that the technology in the factory has not been leaked."

At the beginning, they also thought about making the car simpler, but He Jing felt that if they wanted to do it, they had to make good things. As for the simple ones, they were too easy to be imitated, so it was normal for this to happen.

Thinking of this, Jiang Ping asked again, "How much does their remote control car cost?"

"Eight yuan, there are quite a few people who buy it." Speaking of this, He Shenghua became worried. This kind of simple remote control car is much cheaper than theirs, and it must have an impact on their sales.

Jiang Ping nodded, and understood He Shenghua's worry. After all, the price was more than doubled, which naturally had an impact on their sales. Their cars were toys rather than models, and most of the structures were there. , and the volume is much larger. If it is enlarged, it may be able to drive a real car.

Seeing that Jiang Ping didn't speak, He Shenghua couldn't help it, "Then what should we do? Just watch it like this? Or lower the price? Otherwise, we won't be able to compete!"

Lu Fusheng hurriedly said, "This is not a price reduction. A large price reduction will not only fail to boost sales, but will also dissatisfy the customers who bought it before. After all, we are not food, let alone out-of-season clothes."

It is the stupidest decision to lower the price. Now Jingyuan’s remote control car has gained some fame. It is a good gift for children in middle-class and above families. Many children are proud of owning their cars.A price cut will undoubtedly reduce your own brand value, and will make those who have bought it feel that they have bought it at a loss, which is not acceptable.Besides, their profits are not very large, too many price cuts will lose money, and too little price cuts will not be of much use.

Jiang Ping also said the same thing, "It's impossible to lower the price, and maybe the price will increase in the future."

He Shenghua looked at Jiang Ping in amazement, a little confused about what he meant by this. Surely this is not a joke, and the price is increasing?

Lu Fusheng understood what he meant very well, "That's not bad. Now that prices have risen, pork used to cost [-] cents a catty, but now it costs [-] yuan. I think it will be [-] yuan in two years."

Jiang Ping nodded and sighed, "Yes, I heard that wages are already rising, and the wages of ordinary workers are almost seventy or eighty."

Lu Fusheng: "Yes, the wages have changed very quickly in the past two years. You must know that when we first built the factory, the salary for one person was about 70. After the new year, it will not work. It will be more than [-]."

The wages of workers must of course be determined according to the national situation. Even though many people are laid off now, it seems that there is a surplus of labor resources, but they are still very conscientious, and the wages they offer are relatively high.

He Shenghua also felt the same way, always feeling that the money was almost worthless.

"Fortunately, we didn't take the money to deposit in the bank, otherwise the interest would not be enough for the rising price trend!"

Jiang Ping also felt generalized, "If you don't talk about salary, just talk about how much the house has risen now. If you want to buy a small yard with the current 3 to [-] yuan, that's not enough."

"Yes, yes!" When it came to the house, He Shenghua couldn't help but feel lucky for He Jing. If He Jing hadn't bought it early, the house they live in now would not be able to buy it for 20 yuan, at least [-]. Yes, the price has risen too fast.

Lu Fusheng also laughed, "Fortunately, I bought the house early!"

Jiang Ping did the same thing, "Yeah, I bought it early and cheap, and the location is good."

He Shenghua rubbed his head, "Oh, I still live in He Jing's house, and I don't know when I can buy it."

If he hadn't invested in this factory before, He Shenghua should have bought a house. After all, he also heard from He Jing that the house will definitely keep rising in the next 30 years. Even if he can't live in it, the investment is still very good.

Jiang Ping glanced at him, and hurriedly said: "Okay, don't talk about this now, let's continue with our previous question."

Lu Fusheng also nodded quickly, "Yes, yes, let's talk about this first, what are we going to do now, let's deal with it!"

He Shenghua immediately turned his mind back to the previous matter, "Yes, think of a way, I can't just watch, you know, our sales are much less now."

Lu Fusheng first put forward his own opinion, "I still feel that the domestic market is limited at present, and foreign markets need to be explored. The Spring Fair will be held in G City soon. I want to go there to have a look, and by the way, go to Shenzhen City too. Let’s see, it’s best to buy a piece of land, the Walkman is estimated to be put into production soon, and the existing factory will definitely not be able to meet the production needs.”

To be honest, they are not very worried about the sales of remote control cars. They have expected this kind of result before, and they also want the future. Not only that, but Wu Yelin has started to research game consoles. This is also a good thing. Not only children like it, but many adults also like it.

As soon as he heard that Lu Fusheng was going out, He Shenghua's heart was ready to move, and he quickly raised his hand, "I, I, I, I will go with you."

Jiang Ping rolled his eyes at him, "If you go with him, then everything will be left to me. I think you want to exhaust me to death."

Before, the two of them hesitated about who to let go, but considering the matter of the Spring Festival in G City, they finally decided on Lu Fusheng. After all, he also represented the factory before, so he was more experienced, and he also knew foreign languages. There is no problem in the language, and he is the most suitable candidate.

He Shenghua looked a little embarrassed when he heard Jiang Ping's words, and scratched his head guiltyly, "Hahaha, there should be no problem, right? You are so good."

Jiang Ping couldn't help giving him a blank look, but he didn't say much, let alone stop him from going.

He Shenghua understood what he meant when he saw him like this, and quickly thanked him with a smile, "Haha, Jiang Ping, you are really kind, don't worry, I will definitely work hard after I pass, and I will never let you down .”

Jiang Ping nodded, accepting his words, "Okay, I hope you will do what you say. Also, every place is not very safe now, you must pay more attention."

Now all parts of the country are not very stable, because of the opening of the economy, especially in those coastal cities, there are a lot of immigrants, so it is relatively chaotic, and there are many thieves and robbers.In addition, many people were laid off, which caused a lot of chaos.

Both He Shenghua and Lu Fusheng nodded, but there should be several people passing by them this time. If they go by train, there shouldn't be any major problems, as long as everyone travels together.

After deciding on this matter, the three of them continued to discuss car sales.

Jiang Ping: "The price can't be lowered, but we can do some activities. By the way, Brother Lu, what happened to the Walkman production line?"

Lu Fusheng calculated the time in his mind, "The production line is about to be remodeled, and it is estimated that production will start in half a month, but the output is very limited."

Jiang Ping nodded, and thought about it again, "This is no problem, we can take our time, but the facade can start, we can build an experience store, put Walkmans and cars in it, and there is Get more tapes in."

The Walkman is an expensive item, so naturally it can't be put on a street stall. According to the time, preparations will start now, and it will be ready to be put on the shelves when the time comes.

He Shenghua knew about this, and immediately said: "I know about this. I have already found several suitable stores. I just need you to go and see which one is better."

Jiang Ping: "This matter needs to be resolved as soon as possible. We'll have a look later and try to settle it today."

Lu Fusheng sighed, "Oh, I guess we'll be busier and busier in the future, but right now we're not enough manpower!"

Jiang Ping thought for a while, "We can start recruiting people, not only the workers, but also the management, and now we can start to train them slowly."

Lu Fusheng shook his head, "It's a bit difficult. There are not many people who understand management. Even if there are, they may not be willing to come to us."

Now some people have started to go to the sea, but more experienced people build factories by themselves, and not many work for others, let alone those college students. Not a small factory like them.

He Shenghua scratched his head irritably, "Trouble!"

Jiang Ping ignored his complaints, and continued to say to Lu Fusheng: "Even if it's troublesome, we have to do it. You can also take a look at Shenzhen City. If it's okay, we will build a factory there in the second half of the year. Then you I guess I'll be there most of the time."

Lu Fusheng nodded, "There is no problem with this. I have already discussed this with my family. If it is stable, I will take them there."

Jiang Ping smiled, "It's not that fast yet, and maybe I'll go there too."

In the plan planned by He Jing and them, in the future, the capital will mainly do research and development technology, including some sales work. As for production and packaging, they will all be transferred to Shenzhen City. Jiang Ping will definitely have to go there by then. But when Jingyuan's technology has developed to a certain level.

Lu Fusheng smiled, it would be a good thing if this happens, it means that their company has developed well enough.

But now Shenzhen City is developing very fast, and it is close to the metropolis of G City, and it has developed quite well in the past.

"By the way, by the way, think about what activities we can do at that time!" Jiang Ping suddenly reminded again.

He Shenghua scratched his head, alas, headache.

Although it was a headache, He Shenghua and the others quickly settled on the event plan, the Walkman car combination package, the new product lucky draw, etc. Anyway, how to do it when it is so lively.

There is also the matter of the storefront. They chose a storefront in a relatively prosperous area, and the place is relatively large. After that, it will be a matter of decoration.

Before Lu Fusheng took He Shenghua to City G to participate in the Spring Fair, their walkman production line had been remodeled, and it happened that they could bring two kinds of products there this time.

He Jing also heard about this matter, but he didn't care to pay attention to it anymore, their projects were very busy.

In the laboratory, He Jing is busy. The Semiconductor Research Institute is currently trying to produce some chips. He Jing needs to get the design drawings out as soon as possible and realize the structure. This is a very troublesome thing, and others can't help much. Busy, only He Jing will come by himself, after all, he is the one who knows the mobile phone best and the product he wants to make.

Considering the size of the current chip, He Jing has a lot to consider.

He needs to consider the capabilities of the lithography machine and the fit of each component...

This is a separate laboratory, he needs a quieter environment, so he didn't come to disturb him.

The chip is very important and is an important part of the processor, including the processor chip, power management chip, memory chip and so on.This is only what a simple feature phone needs. As for a smart phone, it needs more types of chips and is more troublesome.

He Jing scrapped another blueprint, put down the pen, and felt a little headache. He was used to the high-end chips of later generations. Making such low-end chips is really embarrassing, and there are too many things that need to be changed.Before this era, He Jinglai had disassembled the mobile phones of several mobile phone companies, and used some equipment to observe the chips in these mobile phones, so he had some understanding of those things.

The difficulty now is not that there are no good ideas, but that these ideas cannot be realized. After all, the technology is not up to the mark, and the current chips are too backward.

Just as he was suffering from a headache, there was a knock on the door of He Jing's laboratory. He got up to open the door. He was not surprised that there was Professor Han outside the door. During this time, Professor Han often came over.

Seeing He Jing, Professor Han smiled, "How is it? Is everything going well?"

He Jing smiled helplessly, "It's a little troublesome." He let people in and closed the door after speaking.

"What's the trouble? You're usually not the kind of person who talks like that?" Professor Han raised his eyebrows in surprise, walked to the place where the blueprints were placed, and picked up a copy to read.

"Is it out of ideas or something?"

He Jing scratched his head depressingly, "There are too many ideas, and they are too good, but the current technology can't achieve it."

With the current technology, only 2G mobile phones can be developed, surpassing the first-generation analog cellular network, and using digital network transmission, which will improve the efficiency of calling the network, enhance the signal, and expand the scope of use.Such a mobile phone is not very difficult in terms of technology, and the chip circuit diagram is not that complicated, after all, the functions are still relatively small.

What He Jing needs is to delete, which is also very troublesome.

Regarding He Jing's words, Professor Han was speechless. He said that he was not afraid of being beaten. Doesn't this mean that the chip is not good?

"You!" He shook his head helplessly, and said no more. In his opinion, He Jing is not the one who needs to be comforted.

He Jing felt much less bored this time, so he thought about asking Professor Han why he came here.

"Teacher, what are you doing here?"
