Chen Zhiyun had two recruits in his dormitory, but when he saw Chen Zhiyun taking Ruan Haocheng, Guo Tao and Chen Ziqiang in, he greeted them and walked out, giving up the dormitory to them.

When everyone sat down, Chen Zhiyun couldn't wait to open his mouth.

"Haocheng, why do you think Mr. Ming wants to tell us about circuits?"

The purpose of letting them learn circuits must not be as simple as learning to connect to an electric light.

Ruan Haocheng frowned and shook his head, "I can't think of what he wants to teach us in the later stage?" ”

After the words fell, Ruan Haocheng turned to Chen Ziqiang, "Ziqiang, since you are in the middle school of electrical maintenance, the circuit should be very simple for you, right?" ”

Chen Ziqiang nodded, "Although I don't dare to say that I am completely proficient in this circuit, ordinary circuits should not be difficult for me." ”

"Ziqiang, when you were in the job, in addition to learning electrical maintenance, did you also know other circuit-related knowledge?"

Ruan Haocheng can contact the circuit related, that is, a light bulb at home, and he really doesn't know much about the places where the circuit can really be used in the outside world.

"In addition to electrical maintenance, I know the most about the circuits and electrical components needed in the production process of the tractor factory, that is, the circuit access and maintenance of the production line control system, which I learned from my father."

"Haocheng, what Ziqiang said doesn't seem to have much to do with the troops." Chen Zhiyun interjected.

They hadn't heard of any production plants at their base, so the access and maintenance of the production line control system should not be something they would learn later.

"If it is said that it is to be used in the army-" Chen Ziqiang twisted his eyebrows and thought carefully, "the broadcasting system should be counted as one." ”

After lunch and dinner, there will be a half-hour radio broadcast in the camp, mainly to broadcast relevant news.

"Shouldn't the telegraph system also be counted as one?"

Listening to Chen Ziqiang talk about the broadcasting system, Guo Tao couldn't help but think of the telegraph system he had learned in the police academy.

"Yes, yes, the telegraph system will definitely be used in the army."

"What about the phone?" Chen Zhiyun remembered the phone in his father's office, and couldn't help but add.

For Ruan Haocheng, Chen Ziqiang and Guo Tao, the phone call is too unfamiliar.

"The telephone should also be counted as an indispensable tool for communication within the military."

Chen Zhiyun's words reminded Guo Tao of the phone on Wu Yingjie's desk when he went to Wu Yingjie's office last night.

"Radio, telegram, telephone? All of this seems to be directly related to communication, but what kind of will we learn in the future? Chen Zhiyun frowned and muttered in a low voice.

"Communication? Correspondence? Nguyen Ho Thanh couldn't help but think of the importance of sending accurate signals to each other in the books he had read about warfare.

"Maybe we'll learn all the communication tools in the future." He still doesn't quite know the difference between communication and communication.

Chen Ziqiang's brows couldn't help frowning, "I haven't been exposed to communication tools in my job, but since Mr. Ming's lecture to me starts with circuits, I think they should be inseparable from circuits." ”

"Yes, yes, Ziqiang is right, we will learn the circuit first, and it will be much easier to learn about communication in the future."

Chen Zhiyun was woken up by Chen Ziqiang, and instantly felt relaxed and happy.
