I asked He Siliang for a letter of introduction, saying that it was a letter of introduction, but it was just a note, saying that Yu Jingque would show it to the teacher in class at that time.

After three days of class, Yu Jingque had already begun to prepare, and asked He Siliang about some very basic things, worried that when he arrived at the place, his eyes would be black and embarrassing.

But it's not good to disturb He Siliang too much, Yu Jingque actually doesn't know much.

Three days passed quickly, and Yu Jingque began his journey to class.

Yu Jingque is no stranger to the police academy, and he came over with a familiar car, so he went to find Tianhai Yingzhu first.

"Yu Sang." When Eisuke Amami saw Yu Jingque, he greeted him with a smile.

"Mr. Amami still remembers me, and I'm honored." Yu Jingque said in Japanese.

"Yu Sang, your Japanese has improved again, but my Chinese has deteriorated so much that I rarely teach students in school and can't get exercise." When Eisuke Amami saw Yu Jingque, he seemed in a good mood.

"Mr. Tianhai is modest, who dares to say bad Chinese like yours?" Yu Zhenque has already begun to speak in Chinese, helping Eisuke Amami practice.

The two exchanged a few words, and Amami Yingsuke said, "What is Yu Sang doing today?" ”

Eisuke Amami knew that Yu Jingque was now a member of the Special Services Section, and he suddenly came to the police academy thinking that there was some mission.

"I'm here for the training class." Yu Jingque said a little embarrassed.

Training?

Eisuke Amami thought for a moment and said, "Was it Kenji Hashimoto who taught it?" ”

Kenji Hashimoto, who is the lecturer of this training class, Yu Jingque heard what He Siliang said, and nodded immediately.

Seeing Yu Jingque nodding, Amami Eisuke laughed and said, "Who should I be, it turned out to be Hashimoto-kun's class, you come with me, and I will take you over." ”

"Don't bother, I'll just go over by myself." Yu Jingque said prevaricatingly.

"It's already at school, what's the trouble, let's go." Amami Yingzhu enthusiastically took Yu Jingque over.

When I came to the classroom, there were already a lot of students sitting inside, and it seemed that they were all participating in the training this time.

However, Kenji Hashimoto was standing outside and had not yet gone in, because the time had not yet come.

"Hashimoto, this is ......" Eisuke Amami seems to have a very good relationship with Kenji Hashimoto, so let's introduce Yu Jingque at the moment.

Originally, Yu Jingque was going to take out the strip that He Siliang gave him, but now that he thinks about it, he feels that it is not necessary, the relationship between Eisuke Amami and Kenji Hashimoto is better than He Siliang no matter how you look at it.

Kenji Hashimoto is not a person who is good at talking, which is a bit similar to He Siliang, is it possible that people who are engaged in this research are not good at these?

Yu Jingque was the first to go in, and the police officers knew some of Yu Jingque, and some did not, but among these people, there were many hidden dragons and crouching tigers.

When the time was up, Kenji Hashimoto came in from outside.

At the beginning, it was a very regular introduction, but Kenji Hashimoto briefly introduced himself and then began his own teaching.

There was a radio station on the table, but now I didn't explain it, but I talked about the origin and development of the radio station.

These Yu Jingque have already understood, so they don't really run over without understanding anything, and among the people present, they will only know more than Yu Jingque, and will not know less than Yu Jingque, so Hashimoto Kenji just said it simply, and did not ask questions or talk in depth.

After that, Kenji Hashimoto talked about more things, and what interested Yu was the invention of Chinese code.

The earliest telegraphs could not transmit information in Chinese because of the large number of Chinese characters and complex structure.

In the end, it was decided to use a four-yard telegram, that is, four Arabic numerals, to represent a Chinese character.

At this point, Kenji Hashimoto asked, "Does anyone know why the four-code telegram is used?" ”

As soon as this question came out, many people couldn't wait to speak, but Kenji Hashimoto's class demanded order, and everyone could only raise their hands.

"Here you go." Kenji Hashimoto ordered someone at random.

The man stood up and said aloud: "There are as many as 60,000 Chinese characters, and there are only 10,000 commonly used Chinese characters, so it is represented by 10 to the fourth power, which is enough for 10,000 words, which is the origin of the four-yard telegraph." ”

"Who knows the earliest Chinese character code book?" Kenji Hashimoto asked again.

He suddenly remembered that Eisuke Amami asked him to take care of Yu Jingque, and motioned for Yu Jingque to get up and answer.

Yu Jingque's face was a little embarrassed, he knew a lot of knowledge, but he worked the radio, he also understood this knowledge, he saw it, but he swept it away, and he didn't remember it in his head at all.

Now Kenji Hashimoto is kindly asking, but Yu Jingque can't answer.

Kenji Hashimoto also found that Yu Jingque's face was embarrassed, and he was a little unhappy in his heart, thinking that the person introduced by Eisuke Amami was a level?

But he also felt that Eisuke Amami was not such a person, if there was no level, Eisuke Amami would not be able to look down on him at all, how could he take the initiative to introduce it.

Suppressing the doubts in his heart, Kenji Hashimoto said, "Listen carefully. ”

"Yes." Yu Jingque replied honestly.

"Here you go." Kenji Hashimoto asked another student.

The student stood up proudly, did not forget to glance at Yu Jingque, and said: "In 1873, the French personnel stationed in China, Wiggie, selected more than 6,800 commonly used Chinese characters with reference to the radical arrangement method of the Kangxi Dictionary, and compiled the first Chinese character code book, called "New Book of Telegraphs". Later, Zheng Guanying adapted it into the "New Edition of China Telegraph......"

Sprinkled with joy and said a lot, this student was triumphant.

The other students are not surprised, this kind of thing, who doesn't know.

But everyone looked at Yu Jingque's eyes, and there were a little more weird, is this kid here to smash the field, I don't know anything, what are you doing.

In the following study, Kenji Hashimoto introduced the clear code that is used today.

That is, when you go to the telegraph office to send a telegram, you will use the four-character code.

Similarly, high (7559) (paste 5221) lamb (5021) cake (4741).

These are clear codes, that is to say, the telegraph office will generally use such four-character codes, you send a report from Bingcheng to Fengtian, and from Fengtian to Xinjing, basically like this.

However, these are for ordinary people, and the military aspect is naturally encrypted, but Kenji Hashimoto did not say much about encryption.

What surprised Yu Jingque even more was that among the students present, many of them already knew how to memorize this code.

In fact, it is not surprising that many of these people have already arranged for their families to work at the telegraph office, so it is not surprising that they will know these things.

Yu Jingque was like a book from heaven, and he spent the first class of his own training.

I thought that I would touch the radio station in the first class, but now Yu Jingque finally understands that he thinks too much, and the radio station is not even touched.

And the other trainees, who don't care about the radio at all, have already touched it.

On the contrary, when I look back on the content of Kenji Hashimoto's lecture today, I feel that I have benefited a lot.

But do you say that Yu Jingque has a feeling of benefiting a lot?

Not at all, in Yu Jingque's opinion, he felt as if Kenji Hashimoto didn't say anything, just read from the book.

That's because Yu Jingque doesn't understand, so naturally he can't hear the deep meaning of Kenji Hashimoto, and other students are different.
