Chapter 225 On how expensive it was to make a phone call in 1937!
Pray and expect, this is Liao Yaquan's psychological state.

The task of finding Zhang San has been assigned for a long time. However, due to the lack of identity information and physical characteristics, the entire task process has not made breakthrough progress.

Really, there is no age information, no accurate identity information, no facial features, and nothing to search for. It is more difficult than finding a needle in a haystack to find a person named Zhang San in the Pingjin area.

After such a long search, according to the mission file records, the entire Pingjin area called Zhang San can form a brigade, but after careful screening and judgment, none of the Zhang Sans met the judgment criteria.

The criteria for judging Zhang San are what Liao Yaquan and his subordinate intelligence personnel have analyzed and summed up based on the existing information. First, knowledge level, second, temperament, and third, character.

First of all, it can be affirmed that Zhang San's knowledge level is very high, because he is a scholar who compiles systematic mechanical drawing standards.

Secondly, Zhang San must have a special scholar temperament. As a scholar, there is something in his bones that cannot be concealed or hidden.

Finally, with the blessing of knowledge and temperament, the opponent's character must be very special, proud, confident, and very hostile to Japan.

It is a pity that none of Zhang San from this brigade met the above criteria.

Now Liao Yaquan, who has been seriously warned by Tu Feiyuan, has to find another way and adopt a new method to find Zhang San.

This method is to enter the editorial department of Tsinghua Journal, get Zhang San's mailing address and relevant information, and then trace the source according to the mailing address and relevant information.

But here comes a problem.

Tsinghua Park is extremely repulsive of the Japanese. There is not a single Japanese student in the entire school. The teachers and staff are full of patriotism and scoff at the Japanese and traitors. This situation makes it impossible to carry out intelligence work.

Liao Yaquan had to play in person, forged the identity of returning from studying abroad, and entered Tsinghua Garden in the name of applying for the editor of Tsinghua Journal.

"Finally, I hope that this Zhang San is in the Pingjin area, and I hope that the judgment standard is correct..." Liao Yaquan came to the editorial department leisurely, a cultural connotation came on his face, took a deep breath, and went to the editorial department.

If this Zhang San is not in the Pingjin area, it will mean that the search for so long has failed, and it will take more energy and time to clear the opponent.

If the judgment standard is wrong, it means that the direction of the whole task is wrong.

In fact, even if these conditions are really met, the probability of being able to find Zhang San is less than 20%.

In the early morning, the bright sunshine, which symbolizes hope, appears, reflecting everything in the world.

Here, Liao Yaquan, who turned into a top student studying abroad, entered the editorial office of Tsinghua Journal. On the other side, Yu Hua had breakfast and went to the nearest public telephone booth.

As the highest-level university in China, the infrastructure construction of Tsinghua Park is at an advanced level compared with the whole country. Not only has it established a nuclear physics laboratory and a large number of laboratories, but also built four public wired telephone booths in the school to build a public telephone communication system of Tsinghua University. The Beiping Telephone Bureau can contact any place in the city with a landline.

Of course, there was also the concept of 'domestic long distance' in this era. Telephone lines in Pingjin, Pinghu, and Pinghan were extremely expensive. Except for the wealthy, nobles and politicians, almost no one used them.

Make a Ping-Han phone call, talk for 5 minutes, and charge five oceans.

I have to say, if there is a boy who often makes phone calls to girls for more than 30 minutes these days, it is definitely true love and really rich.

On how expensive it was to make a phone call in 1937...it turned out to be outrageously expensive.

The above are considered normal charges. In some areas and cities, the telephone company can charge up to 1 or even 2 oceans for a 5-minute call.

When I came to the nearest public phone booth in the school, there was a newsstand-like shop next to it, selling public phone coins. Yu Hua stepped forward and took out a piece of ocean to buy eight public phone coins.

Each public telephone coin can be used for 1 minute of conversation, and hang up directly after timeout, so that no one can take advantage of it.

Looking at the time, it was already 55:59. Yu Hua bought public phone coins and waited quietly. When the time on his watch came to [-]:[-], he turned around and entered the phone booth, and dialed two coins.

"Connect to No. 11 Dongtang Hutong, Jianguomen Gate, Dongcheng." After dialing with great effort, Yu Hua said in a serious voice when the voice of the staff of the Peiping Telephone Bureau came from the other end of the phone.

"Please wait."

The telephone office staff responded.

"Okay." Yu Hua held the microphone and waited quietly.
About ten seconds later, the call was connected, and a familiar and powerful male voice came from inside, with a slightly puzzled voice: "Yu?"

"Mr. Rabe, it's me, Yu Hua." Yu Hua smiled and spoke calmly and naturally.

In the room, Rabe clenched the microphone with his right hand, glanced at the middle-aged military attache standing in front of him, nodded affirmatively, and breathed a sigh of relief: "God, you are really on time, it's exactly eight o'clock."

After getting Rabe's nod, the middle-aged military officer showed a haggard look on his face, and his heart relaxed slightly.

For the past ten or so hours, he has not rested at all, and has been worrying about this sudden event.

There is no comparison between personal life and the formula of Y-type armor steel with extremely high military value.

"This is our agreement and respect for you, Mr. Rabe, about that matter, what happened in the end?" Yu Hua's tone was natural and sincere, giving people a sense of a gentleman. The sentence cuts directly to the subject and asks.

"Yu, you have succeeded, and the country has agreed to carry out this transaction. In addition, in order to show his sincerity, Mr. Guderian has begun to mobilize all the machine tools and equipment on the list to be shipped to Hamburg for shipment. As long as we sign a transaction agreement, the machine tools equipped with machine tools will be processed. The freighter will leave the port immediately." Hearing Yu Hua's question, Rabe took a deep breath, slowly gave the final result, and then gave another good news.

Sincerity.

In order to show the sincerity of the Germans, Guderian ordered the mobilization of all the mechanical processing equipment on the required list before the transaction between the two sides entered the next stage and shipped to Hamburg for shipment.

From a commercial point of view, such behavior is not appropriate, but from a military point of view, such behavior is very...

Loyalty!

"Mr. Rabe, thank General Guderian for me. If you can, please tell him a word for me." Hearing Rabe's words, Yu Hua was stunned for a moment, and he immediately felt that Guderian came from this guy. The sincerity of the father of Blitz, who was about to hang up the phone, was silent for a second, ready to give a gift in return.

"Speak, Yu," said Rabe.

"Efficient and confidential communication can make the tank have higher combat effectiveness." Yu Hua said softly: "At 6:30 this evening, I will go to your residence to discuss the transaction in detail."

This sentence is a gift from the status of a hardcore military fan.

Rabe heard it, pondered it carefully, and shook his head gently. He who was born in the non-armored field could not understand the meaning of this sentence: "Okay, Yu, I will tell you the truth."

"Goodbye, Mr. Rabe." Yu Hua smiled and hung up the phone immediately. It is not safe to talk about important things on the phone. Although there is no serious concept of eavesdropping in this era, there is currently no advanced technical equipment to listen to calls. content.

But, it doesn't matter.

Security awareness must be there, not afraid of [-], but just in case.

There was not much time left for the call. Putting the microphone on, Yu Hua left the public phone booth and went to the school. This morning, there was Professor Yang Wuzhi's calculus class, which happened to be used for fishing.

Yes, that is the professor Yang Wuzhi in history.

"Mr. Military Attache, Yu Hui will come to discuss in detail this evening at 6:30." On the other side, Rabe put down his home phone, stood up, and said to the middle-aged military attache.

"Mr. Rabe, thank you for your hard work." Hearing Rabe's answer, the middle-aged military attache completely relaxed, with a serious and solemn face, and then extended the most lofty etiquette to Rabe.

"This is what I should do, but I don't know what impact what I have done will have an impact on this land and country..." Rabe shook his head and looked at Peiping outside the window. City, said softly.
