Siheyuan: I eat melons while doing scientific research

Chapter 1311 An Old Acquaintance (5k)

Just as the comrades from the water conservancy department were expressing their gratitude to Gao Zhendong, Lou Xiao'e also received enthusiastic applause at the Second Affiliated Hospital of Beijing Medical University.

Before coming to the Second Affiliated Hospital of Beijing, Lou Xiao'e made careful preparations. Unlike Gao Zhendong, who was a seasoned veteran and often spoke on various occasions, she was nervous but also a little excited. Naturally, she had to make thorough preparations so that she could feel a little more at ease.

Fortunately, no matter how she felt, her achievements spoke for themselves. She did everything she was supposed to do, big or small, and was involved in every aspect. She had the talent to offer.

In the field of scientific research, apart from extremely abstract disciplines like mathematics, as long as one has done solid work in other disciplines, there is no problem in giving lectures. Simply explaining the process and the journey can greatly benefit the audience.

Of course, the "abstraction" in mathematics here is not a derogatory term; it is truly abstract. Mathematics is something that you simply cannot understand if you don't understand it.

Lou Xiao'e's lecture, which she had prepared meticulously, received great praise at the Second Affiliated Hospital of Beijing Medical University. This was due to her experience, age, achievements, and so on.

"This senior sister is so beautiful."

There are plenty of beautiful people, but few achieve what she has.

"Yes, yes, especially since they're so young."

"The treatment plan for pulmonary tuberculosis, what a great achievement."

"I heard that she was noticed by a teacher there before she even graduated, and was recruited as soon as she graduated. Our school's teachers felt quite sorry for her."

"What do you know? When they were studying here, they published a book that is now being promoted and used all over the country."

"Really?"

"Really? It's the book you were flipping through yesterday."

"The Concise Handbook for Primary Care Physicians? She wrote that book? I really didn't notice! I should have brought it with me and asked her to sign it."

"And it wasn't just her; her lover was with her too."

"Wow...you got married before even graduating?"

"How amazing! The most impressive thing is that she had a baby while studying at our school, and it didn't interfere with her studies at all."

"Is this a deity?"

"A batch of books at the school were donated by her and her husband. You wouldn't believe it, would you?"

"..."

During the break, the students listening to the lecture below were talking animatedly, but the teachers were much more composed, mainly because it wasn't appropriate to get involved in these matters with the students.

Meanwhile, Lou Xiao'e's department head was taking advantage of his break time to chat with her.

"Is your spouse still so busy with work?" The department head also had a deep impression of Gao Zhendong. There weren't many students with family members to begin with, and even fewer with such special family members. Although he didn't know exactly what made Lou Xiao'e's family so special, he just had that impression.

“Yes, but I don’t know anything about his job; it’s not his profession,” Lou Xiao’e said with a smile.

"Your work does overlap, for example, that book, hahaha." The department head laughed, and then asked about the child's situation.

When Lou Xiao'e finished her lecture, the hall erupted in prolonged applause.

As Lou Xiao'e stepped down from the podium, quite a few students came to ask her to sign copies of "A Concise Handbook for Primary Care Physicians." Many students had noticed beforehand that she was one of the main authors of the book.

There were even foreign students among them.

We have been helping third-world countries train their own medical personnel ever since we gained the necessary capabilities.

"Lou, thank you for your lecture and your book." For third-world countries, the Concise Handbook for Primary Care Physicians is extremely practical, except for the traditional medicine section which is somewhat difficult to apply due to cultural, geographical, and local species limitations. It is even more significant than some advanced medical technologies.

For them, the primary concern is ensuring that their people don't lose their lives or suffer serious consequences from common illnesses like colds and fevers; more serious illnesses are simply out of their reach. A somewhat hellish reality of the 21st century is that people in some continents aren't afraid of AIDS at all, because they are unlikely to live long enough for it to take their lives.

The "Concise Handbook for Primary Care Physicians" is precisely such a book, perfectly suited to their needs and with a sufficiently broad scope. Our comrades carrying out foreign aid missions have also keenly recognized this and have done a great deal of work in this regard.

Lou Xiao'e was in a great mood when she signed the book. It was a huge affirmation for her. How could her and her husband's book help patients on another continent thousands of miles away? It was a novel feeling for her.

She even felt a little regretful that she couldn't get Gao Zhendong to sign the book with her. Just imagine how wonderful it would be if both of them had their signatures on the book.

However, she also knew that this idea could only be a thought. Although she didn't know the specifics of her man's special qualities, she knew a little about them in general terms, so this matter was completely impossible.

"Lou, this is something I brought from our tribe. It represents good wishes for people. I'm giving it to you to express my gratitude." Although the words were very stiff, Lou Xiao'e still roughly understood what she meant.

"No, no, no, you should keep this beautiful thing for yourselves. I appreciate your kindness," Lou Xiao'e said with a smile, politely declining the wooden pendant, which had a slightly primitive and wild style.

It's not that I think it's ugly, but if it really represents the tribe's blessing, then it's probably very important to them, so it's better not to take it away from them.

"No, no, no, you must accept it. I found this out specifically because I heard from the school that you were coming to give a lecture. Giving it to you makes it more meaningful." It seems that the "Concise Handbook for Primary Care Physicians" is really important to this foreign student's hometown, as she insisted on it.

As they watched this scene, two comrades nearby were talking.

"is that OK?"

"There shouldn't be any problem. We contacted the customs officials, and they checked it when it came in. It was wood and a little decorative metal, nothing else, and there were no electromagnetic signals. We also asked the foreign affairs department, and they confirmed that there are indeed sculptures and pendants of this style in the area that fit this meaning. And we've confirmed that so far, it hasn't been switched."

"Is it solid?" You can't tell just by looking at the outside.

"It's solid!" I knew that just looking at the outside wasn't enough.

"Oh, that's good."

As the two were exchanging words, Lou Xiao'e, unable to refuse their kind invitation, accepted the blessing from afar. To be honest, she was quite happy about it.

So when Gao Zhendong returned home, he saw Lou Xiao'e with a happy face hanging things on the wall.

"Hey, this thing is really unique. Where did it come from? It doesn't look like the style of things in China. Did you buy it from the Friendship Store?" The Friendship Store mainly deals with foreign products, but it does have some domestic channels.

"No, guess..." Lou Xiao'e said cheerfully.

"That's the gift someone gave you at the lecture today," Gao Zhendong guessed immediately.

"I knew it wouldn't be difficult for you. This is a gift from abroad, hahaha." Lou Xiao'e took a few steps back, examined it carefully, and said, "Hmm, it's hung up straight."

No wonder this style doesn't seem to be from China. Gao Zhendong looked at it with great interest.

A golden disc is embedded in the surface of the wood carving, with a ring of metal needles of the same color radiating outwards from all sides, making it look like a sun radiating sunlight.

Hey, he's probably still on the path of sun worship.

As for anything else, Gao Zhendong didn't think much of it. This thing was quite big, and since Lou Xiao'e could bring it home openly and honestly, there shouldn't be any problems.

Lou Xiao'e hung up her things and turned to prepare dinner. Everyone, including Gao Zhendong, hadn't been back to the courtyard house for several days.

Gao Zhendong led his two children to his front door and lay down on a deck chair, watching his neighbors come home from get off work and school. This was Gao Zhendong's favorite thing to do when he had free time. Watching these people made him feel that the world was more real and he felt more at ease. If he could catch a glimpse of the changes he had brought to the world, that would be even better.

Banggeng, wearing a red scarf, walked past Gao Zhendong with Xiaodang, who was also wearing a red scarf. He even greeted Gao Zhendong politely and teased the two siblings who hadn't been warned. Banggeng was confident he could handle such young children; he claimed to have more experience than Gao Zhendong.

Xiao Dang is now on the vanguard team too; time really flies! Gao Zhendong sighed inwardly as he watched the two children's backs as they walked away.

"Zhendong, dinner's ready!" Lou Xiao'e's voice came from inside the house.

"Alright!" Gao Zhendong stood up, took the child's hand, and walked into the house. As he turned around, he caught a glimpse of Banggeng and his sister entering the courtyard out of the corner of his eye, and Gao Zhendong suddenly paused. He returned home, said little, and then walked to the sculpture that Lou Xiao'e had brought back and examined it carefully.

Lou Xiao'e noticed his unusual behavior and came over, pointing to the wood carving with her finger.

She didn't speak, but Gao Zhendong understood what she meant: she was asking him if there was a problem with the item.
After watching it again, Gao Zhendong suddenly laughed.

He beckoned to Lou Xiao'e with his finger and picked up the child. The two went outside, and Gao Zhendong said very quietly, "Let's go eat at Sha Zhu's place, and then go back to Mom and Dad's."

According to Gao Zhendong's guess, even if there was a problem with this thing, it wouldn't be a big problem, but just to be on the safe side, he decided to just leave.

He didn't have the time or inclination to gamble.

Lou Xiao'e nodded and, with her child in tow, prepared to walk towards the Intermediate People's Court, asking softly, "Did I do something wrong?"

Gao Zhendong shook his head: "How could that be? It has nothing to do with you. We're old acquaintances, a little commotion is normal. You go first, I'll arrange something and come over, don't worry."

Since he said that, Lou Xiao'e felt relieved and took her child to get a free meal.

Gao Zhendong arrived at the front of the building. Before he could knock, the door opened, and Gao Zhendong went inside without saying a word.

After the door was closed, one of the comrades inside asked somewhat nervously, "Sir, what's wrong?"

The fact that a leader would come directly to them and their group indicates that this is no small matter.

Gao Zhendong laughed and said, "It's nothing, I just have some doubts. If it's true, it's inconvenient to talk or make phone calls at home, so I came to borrow yours for a bit. By the way, could you please help me notify the relevant authorities?"

"Yes!"

Gao Zhendong spent some time speaking to the comrades in the back room before picking up the phone and calling his father-in-law. He didn't say anything else, just that he had something to do and needed his father-in-law to send a car to pick him up later.

After all, there were two children involved, and the ride there would be very bumpy.

After doing all this, Gao Zhendong put down the phone and went to Sha Zhu's house for a free meal.

While he remained calm and carefree, his comrades elsewhere did not share his leisurely mood.

In an office of the National Defense Commission, a comrade put down the phone and the pen he was taking notes with, his brow furrowed.

He looked up and handed what he had written to another comrade next to him: "You make arrangements immediately! I'll report this to the leadership."

The boss had already left work, but he picked up the phone again.

"...Yes, that's right. Comrade Zhendong reported it on his own initiative, saying he had suspicions..."

"Yes, yes... He's not home right now, he's eating at the neighbor's house... Yes, that's the one..."

"His family has already taken him back to his in-laws' house, and he's still waiting at the courtyard house..."

"Yes! Safety will be guaranteed! Yes!"

I don't know what the leader said on the phone, but it must be related to security. Even if it's true, whether or not we can catch the person is not the most important thing; protecting the person is.

Two disguised radio work vehicles urgently departed from a location in Beijing and headed towards the vicinity of Nanluoguxiang.

These two radio work vehicles look no different from ordinary vehicles, and they are not even off-road vehicles, but the latest Jingqi 315 produced by Beijing Automobile Factory. However, their interiors are quite different.

In a courtyard not far from No. 95 in Nanluoguxiang, what makes this courtyard slightly different from the surrounding ones is that its rear enclosure is two stories high. It's unclear whether this courtyard house was originally like this or whether it was added by later residents.

In short, this courtyard is one of the tallest buildings within a 300-meter radius of No. 95.

Two radio work vehicles have arrived nearby, and the comrades inside are communicating intensely.

Are there any unusual signals?

"Not yet."

"I don't have one here either. Let's split up. We can't rule out the possibility that the other side is using a highly directional antenna." Actually, it's also possible that there was no signal to begin with, but those of us doing this job certainly wouldn't be so lazy.

"Well, according to the analysis of the comrade who discovered the problem, if there is a problem, the other party will use highly directional, low-power equipment in order to evade radio surveillance, so we can search near the target area."

This is Gao Zhendong's analysis. After all, the imperial messengers in the capital are not to be trifled with. If the situation matches his analysis, then this is the only path the other side can take.

The two cars separated at an intersection, each heading in a different direction.

In the second floor of the rear building near number 95, a person was adjusting the direction of a device through the glass and thin curtains. He didn't dare to open the window and adjust it directly, so he could only do it indirectly. Fortunately, this device wasn't like the kind that emits light, so it didn't need to be directly visible; as long as there were no metal obstructions in between, it was fine. This gave him some peace of mind, at least he didn't have to show his face.

However, there is a dilemma for him.

It's June, and it's already getting hot. Not opening the windows would seem rather unconventional. But there's no other way; for them, it's a dilemma. Compared to opening the windows and exposing this directional antenna—which clearly isn't something an ordinary household would have—to the public, keeping the windows closed is the only option.

This can be considered a different kind of prisoner's dilemma.

After all, a directional antenna is obviously problematic, while closing the window makes some sense.

He adjusted the antenna and turned on the device.

Almost the instant he turned on the device, the two radio work vehicles that were roaming the area immediately responded.

"There's a signal, but it's not a permitted public frequency band!" The comrades in the two work vehicles responsible for radio signal detection made similar judgments almost simultaneously.

Even in the 60s, it was impossible to find an area in a city without radio signals, as radio and television alone covered almost the entire city.

However, since it's not a permitted public frequency band, there's undoubtedly a problem.

This is another prisoner's dilemma.

With current radio technology, using public frequency bands for cover means that any device using public frequency bands could potentially receive the signal, greatly increasing the likelihood of exposure. At the same time, it also exposes itself to interference from legitimate devices operating on public frequency bands.

Without utilizing public frequency bands, as long as the signal is received by the communication tube, it will appear to them as a bright light bulb, the 100-watt kind.

"Got it? Direction?" Once the direction is determined, the two vehicles can work together to accurately determine the direction of the signal source immediately.

The comrades looked at the TN-LCD display screen on the vehicle. The data between the two vehicles is shared, which allows them to jointly calculate the target coordinates at the fastest speed.

However, the signal display on the screen flashed briefly and was lost.

It's turned off? That's unlikely. This is clearly a listening device, which must be operating continuously.

"Quite cunning, frequency hopping? Keep up, keep up!" The comrades on the work vehicle also had rich experience in fighting the enemy, and immediately knew the other party's method and switched the equipment's working mode.

This tactic worked very well. These days, there are only a few tricks that can be played with radio communication. In the face of a work vehicle with more advanced equipment and more comfortable working conditions, all tricks are exposed.

"I'll let you jump, hahaha..." The comrades on the work vehicle laughed as they looked at the equipment that had established a stable tracking system for abnormal signals.

But their joy was short-lived; they soon realized that the problem was not so simple.

"No, the signal is coming from No. 95 Nanluoguxiang!"

After establishing stable tracking, the signal source was immediately calculated, but there was clearly a problem at this location!
