Riverside police

After receiving a call from his sister, Han Yu didn't dare to make his own decision.

Director Chen stared deeply at the confidential phone in front of him and said thoughtfully: "At the Sailors Club, we can monitor their movements. Even if we go out, we are not afraid of being lost as long as we are in Binjiang. But this trip is different. Oh, especially after arriving in the East China Sea, how can we keep an eye on him?"

The East China Sea is so big and there are so many people and cars that people who have stayed in the East China Sea for two or three years may not be able to figure out the east, west, and north.

Zhang Junyan knew what the director was worried about and asked in a low voice: "What should we do?"

Bureau Chen weighed it up and looked up at Han Yu: "This is an opportunity. Think of a way to see if you can get close!"

"Bureau Chen, are you talking about me?"

"Xianyu, you are young, and they know you better. If you can get close to them, we don't have to worry about losing them, and we can keep track of their every move."

Staying close is one thing, but what you should follow is follow.

With Zhang Suo and the others watching, they were not worried about danger.

Han Yu thought for a while and said with a grimace: "Director Chen, if I just tell them that I plan to go to the East China Sea with them, they will definitely become suspicious."

"If it were anyone else, they would definitely be suspicious. If you were to follow, they wouldn't be suspicious. To them, you are just a child, and they would never think that you are a police officer."

Director Chen thought for a while, then looked up at Zhang Junyan: "The key is to find an excuse."

Zhang Junyan was also worried that he would be lost when he arrived in the East China Sea. He felt that letting Xiao Xianyu stick close to him was the best way at hand. He touched the corner of his mouth and said, "Xianyu, didn't you take the self-study exam? You can use it as an excuse to go to the East China Sea to buy books."

"The books will be distributed after registration."

"Think again, what do you need."

"I...I want to buy a cassette player and some English tapes."

Director Chen slapped the table: "Isn't this a good excuse? It's difficult to buy electrical appliances in Binjiang. You should be able to buy them in Donghai. Just tell them that."

Han Yu didn't expect him to take him seriously, and said hurriedly: "Just saying that, they will still be suspicious. I asked, the radio recorder is very expensive, the cheap one costs five or six hundred, the kind with two decks that can insert two tapes." More than a thousand, where do I have so much money!”

"You don't have it, but your family does! After so many years of reform and opening up, people's living standards have improved, and who hasn't bought one or two household appliances?"

Director Chen knew that Xiao Xianyu had no money and no confidence. He thought about it and smiled: "Not only do you have to say that, but you also have to buy it when you get to the East China Sea. I just said that I would reward you, and this radio is my reward for you."

"Go and buy it!"

"Could it be a fake purchase? Junyan, go to the Finance Department to advance 1,200 yuan. Pay attention to the newness and denomination. Don't let the suspect see that it was just taken out."

"yes!"

The Port Authority is really rich, Director Chen is really courageous...

Han Yu felt as if he was dreaming. He was stunned for a while before he recovered and said cautiously: "Bureau Chen, one thousand two hundred yuan. My annual salary is not that much."

Bureau Chen waved his hand: "If you have any concerns, just treat it as our sponsorship for your institute. Remember to ask for an invoice. It doesn't matter if you don't have one."

More than a thousand cassette recorders were given away as promised, but they seemed nothing compared to the radars and radio stations given before.

Han Yu was so happy that he thought that even if he donated money to the institute, he would not be able to use it for himself in the end.

Seeing how happy he was, Bureau Chen secretly laughed at how easy it was for children to coax him. He looked at the time on his watch and got down to business:

"Then there is communication, such as hearing their conversation and how to send the message out."

Zhang Junyan pondered: "It's not realistic to write with a pen, and it's not appropriate to always be out of their sight."

Bureau Chen thought of Zhang Junyan's previous introduction and asked, "Xiao Xianyu, you graduated from a shipping school. Have you studied teleportation in school?"

In the shipping industry, reporting is a very important job.

Large ships and large tug fleets sailing on the river have telegraph operators, who have to read the power of the entire Yangtze River at three times every day.

The main content of the power supply is the water level, waterway, weather changes of the Yangtze River, navigation beacon configuration and displacement, as well as telegrams related to navigation safety such as large fleets passing through shallow and dangerous sections.

On the hour from 6 a.m. to 11 p.m., you must listen to the bulletin tables from various port radio stations along the Yangtze River. All information related to navigation safety will appear in the bulletin tables.

It is no exaggeration to say that the radio operator is the ear and clairvoyant of the ship.

The same is true for ocean navigation. There must be telegraph operators who understand Morse code. Even navigation semaphores and light signals are Morse code.

Han Yu not only learned it, but also learned it well. He grinned and said, "I have learned it."

"How are you studying? Can you memorize the standard code book?"

"Yes, I started memorizing it from the beginning of school and continued to memorize it until graduation. Last year, the waterway system held a competition called "No More Additions" in our school, and I also participated. Five hundred Chinese characters were translated into four-character codes. I got every one of them correctly. Won first place in each category.”

That was his most glorious time. Han Yu was afraid that they wouldn't believe it, so he took out his small notebook again: "This notebook is the first prize."

Director Chen suddenly envied Xu Sanye for having a subordinate who graduated from Binjiang Shipping School. He tapped his fingers and said with a smile: "The index finger is short and the middle finger is long."

Han Yu was stunned for a moment and said quickly: "I understand."

"Let's do one first."

"Bureau Chen, can you do it too?"

"Whether it is possible or not, you will know just one person."

Director Chen looked at him with a smile, but his index and middle fingers were tapping rhythmically.

He knocked so fast and looked very professional...

Han Yu calmed down, couldn't help but smile as he watched, and quickly tapped in response like him.

Director Chen looked at it for a while and then said with a smile: "No problem, just pass it on. Junyan, go next door to find the political commissar, ask the political commissar to contact the radio station, and quickly find an operator to join the second team."

Just as he was talking, the red confidential phone rang.

Zhang Junyan stood up immediately and walked out of the conference room.

Han Yu realized that the confidential phone number could not be eavesdropped and hurriedly followed him out.

Zhang Junyan was very curious, so he pulled him and asked, "Xianyu, what was Director Chen talking to you about just now."

Han Yu said with an embarrassed look: "Bureau Chen asked me if I had a girlfriend, and I said no."

"Hahaha, I thought he sent you some secret code."

"Bureau Chen knows a lot about telephony. He seems to be very skilled. He knows more about it than I do."

"He used to work as a radio operator in the army for several years. Later, Tigan also worked in the communications battalion, working from platoon leader to battalion commander."

"Old reporter..."

"Let's not talk about this. There are many people in Bailong Port who know you. I'm going to find the political commissar. You quickly call Xu Suo and ask Xu Suo to help make arrangements."

"OK."

…

He asked Huang Jiangsheng to help him buy tickets, and asked Xiao Xianyu to stay close to him.

Xu Sanye felt that the Binjiang Port Public Security Bureau was very unprofessional and handled every case so sloppily. After understanding the situation, he asked in a low voice: "They promised to send a tape recorder?"

"Give me money and let me choose."

"Then pick out the good ones and buy them. Don't be polite to them."

"The good ones are very expensive, costing more than a thousand."

"There's no need to save money for them. You can use it to study after you buy it. We can also listen to music when we have nothing to do. Remember to buy a few more cassettes of songs and see if they have "Fifteenth Moon" and "Blood-Stained Style". Sung by Dong Wenhua!"

The director likes to sing, especially military songs.

Every time he saw Dong Wenhua on TV, he was fascinated by it and sang along with them, even to the point of not being allowed to change the channel.

Thinking that he liked Dong Wenhua so much, Han Yu couldn't help but smile and said: "Yes!"

…

After everything was arranged, Han Yu returned to the Sailors Club with his luggage.

Han Ning saw that he had brought his travel bag and asked in confusion: "San'er, what are you doing with your bag?"

"I'm going to the East China Sea by the way."

"What are you doing in the East China Sea?"

"If you buy a cassette player, you also need to buy English tapes."

"For self-study exams?"

"Um."

"Binjiang doesn't have to be sold?"

"If I can buy it in Binjiang, do I need to go to Donghai?" Han Yu put down his bag, turned around and asked, "Manager Ye, do you know where to buy cassette players in Donghai?"

Ye Xingguo was stunned and said with a smile: "I know, but the price has increased now, it's a bit expensive."

"I have money!"

"San'er, stop making trouble, I'm not worried if you go alone."

"Isn't this Manager Ye? If I buy it, I'll take the boat back. I'm sixteen, not a three-year-old."

Afraid that his sister would be worried, Han Yu added: "Many classmates did not go home directly after graduation. They either went to the East China Sea to play or took a boat to travel to Hanwu. I have never been to anywhere, and besides, I bought a cassette player, and Not here to play!”

Young people all like tape recorders.

There are even many young people playing dance music and disco on the streets with cassette players on their shoulders.

Ye Xingguo didn't find it strange that Han Yu wanted to go to Donghai to buy a cassette player, and secretly made up his mind to take this opportunity to develop Han Yu into a middleman.

After all, the company has "business" in Binjiang and they come here almost every month. If the Han siblings help, no matter what they do in the future, it will be more convenient than now.

Han Ning, however, was unhappy and muttered with a grimace: "It comes out as soon as I think about it. If I had known you were so disobedient, I shouldn't have asked our father to give you so much money..."

"Xiao Han, don't talk about San'er, he bought the cassette player to study!"

Afraid that Han Ning would disagree, Ye Xingguo promised again: "When we get to the East China Sea, I will take him to buy it. As soon as I buy it, I will help him buy a ticket and send him on the ship."

Han Yu didn't want to make Ye Xingguo suspicious, so he said unconvinced: "Sister, actually, you don't need to bother Manager Ye, just tell me where to buy it, and I can find it. After buying it, I will buy the boat ticket and come back."

Han Ning stared at him closely and asked, "Can you find it?"

"I have a map!"

Han Yu opened the bag and pulled out a wrinkled map of Donghai City.

Seeing that the little fellow was so well prepared, Ye Xingguo couldn't help but think of his own youth, and laughed and said, "Xiao Han, did you see that San'er is well prepared?"

Han Ning pretended to be worried and embarrassed, and said with a grimace: "Manager Ye, it's up to you. You know the phone number of the Sailors Club. If anything happens, just call me. "

"As long as I'm watching, nothing will happen."

As soon as Ye Xingguo finished speaking, Yang Daming and Gu Xian arrived with helmets.

As soon as they saw Han Ning, they called "Master's wife" and then greeted Ye Xingguo under Han Ning's introduction.

The fare has been agreed on the phone just now. One trip is fifty yuan, and the two cars add up to one hundred yuan.

Ye Xingguo asked them to go downstairs and wait before knocking on the door of room 218.

Zhang Asheng and Shen Rulan had already packed their luggage, walked out and knocked on the door of the Indian crew.

They chatted for a long time. Although he couldn't understand a word, Han Yu was sure that they were agreeing on where to meet tomorrow afternoon.

…

PS: The standard codebook is compiled by the postal and telecommunications department and is equivalent to the Chinese version of Morse code.

At that time, the communication system of the shipping system was backward. There was no single sideband, let alone very high frequency. Communication relied entirely on radio.
