In the Ministry of War, in the office of the Secretary of War, Zhang Xutuo, the Minister of War, was receiving visiting guests, but the conversation between the guest of honor was often interrupted by the phone ringing outside. Zhang Xutuo first apologized, then picked up the extension microphone next to the desk, pressed a button, and began to speak to the microphone.

When Liu Hulu, who visited, saw Zhang Xutuo calling, found it very interesting. When the other party put down the microphone, he smiled and said, "This thing is so noisy, are you used to it?"

"It's good to get used to it. Although it's a little quarrel, it's really convenient." Zhang Xutuo smiled and asked the other party: "Don't your official office pretend?"

"What are you pretending? You don't know the mobilization of the imperial guards. It's very important. The sound quality of the phone is too poor. You can't hear who is talking to the other person. Who dares to order on the phone? Who will decide if something happens?"

Faced with Liu Hulu's complaints, Zhang Xutuo did not continue to follow the topic. After all, the imperial guards are very sensitive, so it is best not to inquire about it casually.

Although they are all old people from the Emperor's residence and are all generals from the Hulin Army, they cannot ask what they should not ask, so as not to cause trouble.

However, he was indeed deeply touched by the convenience of the phone. With the phone number, some trivial official duties can be solved quickly without sending people to pass messages.

Liu Hulu came to the Ministry of War to work in business today and asked Zhang Xutuo for business. Because the matter involved archive verification, Liu Hulu waited for the result in Zhang Xutuo's office. When he was free, he started chatting. The topic was naturally this phone number.

Like telegraphs, telephones convey messages through wires. Telegraphs convey telegraph codes, while telephones convey sounds.

Telegrams have been popular for several years, so everyone is familiar with them. However, telephones have only appeared recently and are only used in a small range. So I heard of Liu Hulu, who was from the name of Telephone, and saw that Zhang Xutuo was skillful in using telephones, so I naturally asked for advice.

As the Minister of War, Zhang Xutuo was busy with affairs and did not have so much time to do popular science for others. However, he and Liu Hulu were both from the Hulin Army, and they were always in love, so it wouldn't matter if they did popular science.

He took out the paper and pen and explained to Liu Hulu: "This phone call is not complicated, but you can see, the principle is roughly as follows..."

Taking the Ministry of War as an example, the official office has installed telephone systems, and the offices of the Shangshu, the Minister of the Secretariat, the heads of the departments and the second officials have installed telephone landlines.

These telephone landlines are connected by telephone lines and "connectors". When used, pick up the microphone on the landline and then use a hand-cranked shaking handle on the side of the landline.

The shaker is connected to the hand-crank generator in the landline. After shaking it for a few turns, the generator generates power, connects the telephone line, and connects to the "center" of the telephone system - the wiring table.

The operator on duty at the connection station will ask the person who is calling to which phone number to connect, and then connect it to the corresponding telephone line as required.

The telephone number of each office is divided into hosts and extensions. The signal from the connector station will make the host ring ring. At this time, if the person involved cannot answer the phone in the inner office where the extension is located, the attendant guarding the host in the outside will answer the phone and inform the caller on the other end of the phone to "call it later."

Because the sound quality of the phone is severely distorted, people cannot confirm who the person talking on the other end of the phone is, so the phone can only be used to say some non-confidential things, but even so, it greatly improves the office efficiency of each department.

"Many things can be explained clearly in just a few words on the phone, and no longer need to run errands and pass messages. This alone saves a lot of time."

Zhang Xutuo's "appearance" was very convincing. Liu Hulu had no doubts anymore, but when he saw the office phone ringing from time to time, he felt a little uncomfortable: "I said, this phone is as noisy as a cicada. Don't you feel annoyed by Lao Zhang?"

"For example, when you are focusing on reading, the ringtone suddenly rings, are you afraid you will be shocked?"

Zhang Xutuo smiled bitterly when he heard this: "What else can I do? Just get used to it..."

......

In the Ministry of Transportation and the Secretary of State's office, Yang Xuangan was writing quickly. He suddenly put down his pen and looked up at the outside.

He seemed to hear the phone ringing, but he was not sure, so he saw whether the attendant guarding the phone outside showed up, but it didn't turn out.

Obviously, this is his auditory hallucination.

Since the establishment of the Ministry of Transportation, Yang Xuangan, as the Minister of the House, has been very busy. Since the phone is on, the phone has never stopped whenever it is office hours in his office.

Because there are too many trivial matters to be dealt with, his subordinates often call to report on official duties. Over time, Yang Xuangan developed auditory hallucinations.

He always felt the phone ringing, but it wasn't.

This kind of "audit hallucination" brought a lot of trouble to Yang Xuangan, but when he was used to sending orders on the phone, he was unable to do without this annoying "cida".

There is no doubt that phone calls can improve office efficiency. You can complete a thing by making a phone call and saying a few words. This may not be much faster for ordinary government offices, but it is very important for the Ministry of Transport.

Taking Chang'an Railway Station (South War) as an example, since the Chang'an Railway Station began to operate officially, the coordination of various station affairs alone requires frequent communication between the railway station and various departments. Thanks to the telephone number, the coordination speed is accelerated and no matter how things are delayed.

Chang'an Railway Station is busy with affairs and is currently the most important agency under the jurisdiction of the Ministry of Transport. There are two telephones (exts) on Yang Xuangan's desk. One is connected to the Ministry of Transport's "internal network" with the fuselage in blue and the other is connected to the Chang'an Railway Station (South Station), and the sound of the machine is yellow.

If something happens at the train station, several major officials can contact Yang Xuangan, who is "far away" from the Ministry of Transport through the phone number of their respective offices. This greatly improves office efficiency.

The price is that Yang Xuangan, who answers phone calls frequently, has a problem of "audit hallucination". He always feels that the phone is ringing, and his heart beats faster.

This problem became more and more obvious, so even when he returned to his mansion, he felt the phone ringing sound in his ears from time to time, and his heartbeat was also accelerating.

Why does this happen? It's very simple. The sudden ringing of the phone is tantamount to someone who is concentrating on doing something, which is like someone suddenly screaming in his ear. It would be strange if he is not scared.

Whenever there is a "call", I will be startled, as if I am so scared that my soul trembles. It is not normal to not cause auditory hallucinations over time.

However, compared to the rapid improvement of office efficiency, this little problem is nothing. With the powerful tool of the train station, it can run smoother with the telephone system.

Yang Xuangan thought about it, and suddenly the phone ringtone rang in his ears again. He could no longer tell whether the ringtone was true or not, so he looked up at the door.

The ringtone was interrupted, and the sound of the waiter answering the phone came from outside.

"This is the Office of the Minister of Transportation. Where are you?"

After counting the breath, the attendant turned to the door and reported to him that it was the train station station manager who called.
