I asked He Siliang for a letter of introduction. He said it was a letter of introduction, but it was just a note asking Yu Jingque to show it to the teacher in class.
The class started three days later, and Yu Jingque had already started to prepare. He asked He Siliang about some very basic things. He was worried that if it got to the point, his eyes would be darkened and he would be embarrassed.
But it's better not to disturb He Siliang too much. In fact, Yu Jingque still doesn't know much.
Three days passed quickly, and Yu Jingque began his class journey.
Yu Jingque was no stranger to the police academy, so he came here with ease and went to see Tianhai Yingsuke first.
"Yu Sang." When Tianhai Yingzhu saw Yu Jingque, he smiled and came up to him.
"I'm honored that Mr. Tianhai still remembers me." Yu Jingque said in Japanese.
"Yu Sang, your Japanese has improved again, but my Chinese has deteriorated greatly. I rarely teach students in school and don't get any training." Tianhai Yingzhu was in a good mood when he saw Yu Jingque.
"Mr. Tianhai, you are so humble. Who dares to speak Chinese poorly like you?" Yu Jingque had already started speaking in Chinese and helped Tianhai Yingshu practice it.
The two exchanged some pleasantries, and Tianhai Yingsuke said: "What did Yu Sang do here today?"
Tianhai Yingzhu knew that Yu Jingque was now a member of the Secret Service Division, so he suddenly came to the police academy thinking he had some mission.
"I'm here for a training class." Yu Jingque said a little embarrassed.
Training class?
Amami Eisuke thought for a moment and said, "Is it Hashimoto Kenji who teaches?"
Hashimoto Kenji was the instructor of this training class. Yu Jingque heard what He Siliang said and nodded immediately.
Seeing Yu Jingque nodding, Amami Eisuke laughed and said: "Who do I think it is? It turns out to be Hashimoto-kun's class. Come with me and I will take you there."
"No trouble, I can just go there by myself." Yu Jingque declined.
"We've already arrived at school. If there's any trouble, let's go." Tianhai Yingzhu enthusiastically led Yu Jingque over.
When I arrived at the classroom, there were already many students sitting inside, and it seemed that they were all participating in the training this time.
However, Hashimoto Kenji was standing outside and had not gone in because the time had not come yet.
"Hashimoto, this is..." Amami Eisuke seemed to have a very good relationship with Hashimoto Kenji, so he gave Yu Jingque a good introduction.
Originally, Yu Jingque planned to take out the note He Siliang gave him, but now that he thought about it, he felt that it was unnecessary. The relationship between Amami Eisuke and Hashimoto Kenji was better than that of He Siliang.
Kenji Hashimoto is not a good talker, which is somewhat similar to He Siliang. Aren’t people who do research in this area good at this?
Yu Jingque was the first to go in. Some of the police officers knew Yu Jingque, but some did not. However, there were many hidden dragons and crouching tigers among these people.
When the time was up, Hashimoto Kenji came in from outside.
It was a very routine introduction at the beginning. Hashimoto Kenji briefly introduced himself and then started his teaching.
There is a radio station on the table, but instead of explaining it now, we are talking about the origin and development of the radio station.
Yu Jingque has already understood these things, so he won’t come here without really knowing anything. Among the people present, they will only know more than Yu Jingque, and they will not know less than Yu Jingque, so Hashimoto Kenji
It's just a simple talk without asking questions or explaining in depth.
After that, Kenji Hashimoto talked about more things. What interested Yu Jingque more was the invention of Chinese telegraph code.
The earliest telegraphs could not transmit Chinese messages because there were many Chinese characters and complex structures.
In the end, it was decided to use four-code telegraphy, that is, four Arabic numerals, representing one Chinese character.
At this point, Hashimoto Kenji asked: "Does anyone know why four-code telegrams are used?"
As soon as this question came out, many people were eager to speak, but Kenji Hashimoto's class required order, so everyone could only raise their hands.
"Here you go." Hashimoto Kenji randomly clicked on someone.
The man stood up and said loudly: "There are as many as 60,000 Chinese characters, and there are only 10,000 commonly used Chinese characters, so using 10 to the 4th power to express it is enough for 10,000 characters, which is the origin of the four-code telegraph."
"Who knows the earliest Chinese code book?" Kenji Hashimoto asked again.
He suddenly remembered that Tianhai Yingzhu asked him to take care of Yu Jingque, and motioned for Yu Jingque to get up and answer.
Yu Jingque looked a little embarrassed. He had learned a lot of knowledge, but he had worked hard on the radio. He also understood this knowledge, and it seemed that he had seen it, but he had brushed it all away and did not remember it in his head at all.
Now Kenji Hashimoto asked a question with good intentions, but Yu Jingque couldn't answer it.
Hashimoto Kenji also noticed that Yu Jingque looked troubled. He felt a little unhappy, thinking that the person introduced by Amami Eisuke was of the same level?
But he also felt that Tianhai Yingsuke was not such a person. If he was not qualified, Tianhai Yingsuke would not look down on him at all, so how could he take the initiative to introduce him.
Suppressing the doubts in his heart, Hashimoto Kenji said: "Listen carefully to the lecture."
"Yes." Yu Jingque answered honestly.
"Come here." Kenji Hashimoto asked another student.
The student stood up proudly, not forgetting to look at Yu Jingque, and said: "In 1873, the French stationed in China, Wikije, selected more than 6,800 commonly used Chinese characters based on the radical arrangement method of the "Kangxi Dictionary" and compiled it into
He wrote the first telegraph codebook in Chinese characters, called "New Book of Telegraphs". Later, Zheng Guanying adapted it into "New Edition of Chinese Telegraphs"..."
He spoke eloquently and talked a lot, and the student was very proud of himself.
Other students were not surprised. No one knew about this kind of thing.
But when everyone looked at Yu Jingque, they looked a little weird. Is this guy here to cause trouble? He doesn't know anything. What are you doing here?
In subsequent studies, Hashimoto Kenji introduced the clear code currently used.
This is the four-character code you will use when you go to the telegraph office to send a telegram.
These are clear codes, which means that the telegraph office usually uses these four-character codes. You send a report from Bingcheng to Fengtian, and from Fengtian to Xinjing, basically it is like this.
However, these are for ordinary people, and the military aspects naturally need to be encrypted, but Hashimoto Kenji did not talk much about encryption.
What surprised Yu Jingque even more was that many of the students present were already able to memorize this clear code.
In fact, it's not surprising. Many of these people have already arranged to work in the telegraph office. It's not surprising that they know these things.
Yu Jingque went through his first training class as if he were reading from heaven.
I thought I would touch the radio station in the first period of class, but now Yu Jingque finally realized that he had overthought it, and he didn't even touch the radio station.
And other students don't care about the radio station at all, they have already encountered it.
On the contrary, after recalling the content of Kenji Hashimoto’s lecture today, I feel that I benefited a lot.
But would you say that Yu Jingque felt that he benefited a lot?
Not at all. From Yu Jingque's point of view, he felt that Hashimoto Kenji didn't say anything and was just following the script.
That's because Yu Jingque didn't understand, so naturally he couldn't understand Hashimoto Kenji's profound meaning, which was different from other students.
