Riverside police

Grandpa and grandma drove away when they said they were going back to Binjiang. Dad didn't come home for three days, so Hanhan had to face her mother alone.

When I got home from school and was about to take a rest, my mother came back in a hurry.

"Hanhan, what are you doing there? Hurry up and do your homework!"

"Mom, I just got home."

"What does just getting home have to do with doing homework?" Han Xiangning took off the coat she had just bought, changed into the old clothes she usually wore, ran to the balcony to collect the clothes that were hung out to dry in the morning, and urged: "You hurry up and do your homework, I'll hurry up and cook. After you finish the homework assigned by the school, do the homework assigned by Teacher Liu."

Other people only have to do the homework assigned by the school teachers, but I have to do the homework assigned by the cram school teacher. Even if I can finish the homework assigned by the cram school teacher, my crazy mother will assign homework!

In order to print homework, my mother, who is usually so stingy, actually bought a printer and copier.

Hanhan picked up her heavy schoolbag and walked into her room listlessly. She couldn't help asking, "Aren't we waiting for Dad to come back for dinner?"

"He's working overtime today and won't be back."

"Why does he work overtime every day?"

Han Xiangning took the washed and dried clothes into the living room and folded them while complaining, "So you have to study hard. If you can't even pass the college entrance examination, you may not even have to work overtime every day in the future!"

She started preaching again, as if she couldn't survive if she didn't do well in school.

Hanhan hated these things the most. After thinking about it, she couldn't help asking, "Mom, did grandpa and grandma go to Xichuan? They haven't called me for several days."

It's normal for a daughter to miss her grandpa and grandma. After all, she was raised by her grandpa and grandma.

Han Xiangning looked up and said, "They are still in Sigang. They will go to Xichuan the day after tomorrow."

"I also want to see my mother-in-law."

"It's easy to go to Xichuan. As long as you can improve ten places in the final exam, I will take you there by plane!"

Improving ten places, what a joke, you think this is a 100-meter sprint...

Hanhan complained in her heart, but she didn't dare to say it. Grandpa, grandma and dad are not at home. If you really make mom angry, she will beat you.

There is no way, you can only do your homework first.

...

The Yangtze River estuary was windy and rough at night.

Looking around, the water was pitch black.

Unknowingly, Bai Xinyu had participated in four squats. In total, he had been ambushed at the estuary for eleven nights.

In the first few nights, I had a strong seasickness reaction and almost vomited my internal organs. I have been much better in the past two days, at least I didn't vomit, but I still felt dizzy and swollen with the violent shaking of the ship.

The ambush operation, which has been going on for half a month, is not only a crackdown on previously unsolved cases of theft of navigation lights, but also part of the Olympic water security operation.

The navigation lights are the "eyes" of the Yangtze River and even the Huangpu River. If those bastards are not caught as soon as possible, it will cause great danger to navigation safety. The Olympic Games are about to be held, and there must be no accidents when the whole country is celebrating the opening of the Olympic Games.

The action plan is not complicated, but the difficulties in implementation are obvious.

First of all, in order to ensure that the attack is successful, the encirclement must be tight. To this end, the police force mobilized by Han Yu involved every unit and department of the Maritime Public Security Bureau, accounting for two-thirds of the total number of police officers in the bureau. At the same time, the Changhang Donghai Public Security Bureau was requested for assistance, and the Changhang Donghai Branch dispatched 26 police officers;

Second, the action must be both concealed and timely, which requires each group of ambush police officers to enter the designated water and land locations after nightfall and continuously observe the target with high-powered telescopes;

Third, the sea estuary is windy and turbulent, and it is now the rainy season. No matter how thick the clothes are, they cannot block the wind and rain. The participating police officers can only curl up in the waiting location as much as possible, and their energy and physical strength are particularly consumed; Fourth, although the net has been cast, it is unknown whether the criminal will take action and when to take action. All of these have posed severe challenges to the maritime public security police in terms of overall coordination, tactical application, police situation judgment and combat will.

Han Yu knew very well that the young men were about to collapse, and walked to the bow and asked with a smile: "Xiaobai, can you see the navigation lights?"

"Yes," Bai Xinyu reported through a high-powered telescope, looking at the navigation lights that appeared and disappeared from time to time: "It's clearer than in the cab."

This "clear" is only relative.

After all, the navigation light will rise and fall on the water surface with the wind and waves, and the observation point is set on the patrol boat that is also bumpy and undulating. It is just like a sniper using a high-power scope. It is not easy to lock the target, and you will be dizzy after looking for a while.

Han Yu patted his shoulder and asked him to rest for a while, and personally held the telescope to observe.

Du Ziguo, the head of the Criminal Investigation Brigade of the Maritime Public Security Bureau, and Miao Fangyuan, a full-time fire police officer who had just joined the work, saw that the director was personally monitoring, and hurriedly walked out of the bridge and came to the bow.

The rain was not heavy, but the wind was strong. Wearing a raincoat could not stop the rain from drilling into the neck. A gust of sea breeze blew, and people shivered with cold.

The ambush was a protracted war. Han Yu didn't want them to catch a cold, so he said: "Old Du, why did you come out too? Hurry back to the cabin and sleep for a while. Come and replace us in two hours."

"I can't sleep now." Du Ziguo smiled with a relaxed look.

"You don't need to get wet with us if you can't sleep."

"It's too hot in the cabin, come out and get some fresh air. Besides, the rain isn't heavy."

Han Yu realized that if he didn't go back, they wouldn't go back either, so he simply returned the high-powered telescope to Bai Xinyu and asked everyone to go back to the crew cabin.

After taking off his raincoat and drinking a few sips of hot tea, he felt much better.

He was just trying to see how tonight's shift was planned, when Du Ziguo couldn't help but ask: "Bureau Han, have you told the Navigation Beacon Office about the battery anti-theft issue?"

"As I said, they are organizing technical research."

"Weld a few steel bars and add a few locks to ensure that the battery box is not easily pried open. Is it that difficult?"

"Yes, this matter still requires technical research?" Miao Fangyuan also found it ridiculous.

Han Yu held the tea cup and looked at the dark water and explained: "Do you think those bastards can't pry open the battery box by welding a few steel bars and adding a few locks? If the vehicle used by the criminal is a larger boat, don't say Welding machines, even oxygen and acetylene can be brought. I not only suggest that the navigation aid department strengthen the battery box, but also suggest that they find a way to install positioning and tracking equipment on the navigation aid battery. "

Xiaomiao whispered: "This is not difficult. Technical detection can lock the location of the mobile phone through the mobile phone signal. Isn't this equivalent to installing a mobile phone on the beacon battery? How much is a mobile phone worth? How much is the battery of a beacon light? How much is it worth to install one, it’s a good deal!”

"It's not as simple as you think. You must know that this is at the estuary of the sea, not on the Yangtze River. For technical reconnaissance and positioning, the mobile phone first needs to have a signal. There are no mobile phone signals from China Mobile, China Unicom and China Telecom here. If I really do what you say, Even if it is installed, it will be a white installation.”

"At least it can be tracked. It is impossible for the suspect to sell the stolen goods at sea. As long as they bring the battery ashore, we can ask technical detectives to help us locate the location."

"Do you think the suspect is a fool?" Han Yu pointed at the young man and analyzed: "The bastards who always steal batteries for navigation marks in this area are obviously habitual criminals. They don't know how many batteries they have dismantled. If there is one more part, those bastards will get involved." Suspicious. What's more, we can't keep an eye on it 24 hours a day. Even if we are lucky that the positioning and tracking device is not discovered by them, we don't know how long it will be before we find out that the battery is stolen."

"What should we do?"

"At this stage we can only continue to ambush."

Not only were the boys overwhelmed, but they also had no intuitive understanding of the importance of the work they were doing.

Han Yu thought for a while and changed the topic: "Navigation lights have changed a lot over the years. There has been a saying among the older generation of shipping people, 'There were no lights in the 1940s, kerosene lamps in the 50s, and electrical lights in the 1960s. , electronic lights in the 1970s, neon lights in the 1980s, diode lights in the 1990s, and solar energy in the 21st century. When I used to run a boat and docked at ports in European and American countries, I saw people using solar-powered navigation lights. I was very surprised and thought they were high-tech. I didn’t expect that in China. It’s used now, and it’s made in China.”

Although Du Ziguo is the captain of the criminal investigation detachment, he has rarely been to the estuary before. He asked curiously: "Bureau Han, were there navigation lights in this area when you ran the boat?"

"Yes, but the navigation mark facilities in the port were relatively weak at that time. When the ship was approaching the waters, we held up the binoculars to look for the navigation mark. We couldn't see clearly from the bridge, so we ran to the bow to look at it, and several people looked at it together. In the dark night, only a pinhead-sized bright spot can be seen shining. "

Han Yu recalled the scene of running boats back then, and continued: "Later, in response to the problem of insufficient lighting brightness of coastal lighthouses and light buoys, the Ministry of Transport proposed to 'let the navigation beacon lights light up', introduced and replaced a batch of coastal navigation beacon equipment, and set up a batch of New energy signs have been adopted, and a large number of lighthouses have been built or rebuilt at important seaports and turning points. It is much easier to enter the port at night than before.

Later, the Ministry of Transport formulated the work goal of "networking visual navigation beacons into a chain". If I remember correctly, the biggest move was in 1995. In that year, hundreds of new navigation aids were built or installed, including Donghai Port. The navigation beacons of major domestic ports have implemented a lighthouse chain with cross-coverage lights..."

Just as he was talking, Xiaobai's urgent call came from the intercom.

"Report to the Korean Bureau that the No. 6 light is not flashing!"

"It's gone...are you sure?"

"It's really gone. I...I can't see it anymore."

A dragnet has been set up in the nearby waters, and we must not alert the snake.

Han Yu felt the need to confirm, so he ran to the bow of the ship without even putting on his raincoat, holding the high-power telescope mounted on the side of the ship to observe carefully. Du Zhi also held up a small telescope to look for the beacon light.

"Han Bureau, you really don't dodge, you really can't see me!"

"The target should have appeared!" Han Yu burst into ecstasy, let go of the high-powered telescope, ran back to the bridge quickly, raised the high-frequency radio intercom and shouted: "Every group, pay attention, every group, I am Han Yu, 6 The light buoy may be damaged, please act according to the plan immediately, pay close attention to the water while launching a siege, and search for suspicious ships on the water!”

"One group received!"

"Group 2 received it!"

"Three groups received!"

"Act now, act quickly."

After Han Yu issued the order, he immediately adjusted the call frequency and called: "Traffic Control, this is Han Yu from the Maritime Public Security Bureau. Please answer when you receive it!"

"Traffic control received it, Korean Bureau please speak."

"No. 6 light buoy is likely to be damaged. Please use the VTS system to help us search for suspicious ships near the No. 6 light buoy waters. Once discovered, report it immediately."

"Don't worry, Director Han, we will search immediately!"
