Riverside Police.

Chapter 1337 Waiting at the Yangtze River Estuary (Part )
Grandpa and grandma said they were going back to Binjiang and drove away. 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 standing there? Hurry up and do your homework!"

"Mom, I just got home."

"What does just arriving home have to do with homework?" Han Xiangning took off her newly bought coat, changed into her old clothes, and ran to the balcony to collect the clothes that were hung out to dry in the morning, while urging, "You hurry up and do your homework, and I'll hurry up and cook. After you finish the homework assigned by school, you can do the homework assigned by Teacher Liu."

Others 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 still assign homework!

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

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

"He's working overtime today and can't come 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 in the future!"

He started preaching again, as if one couldn't survive if he didn't do well in school.

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

It is normal for a daughter to miss her grandparents, after all, she was raised by them.

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

"I want to see my mother-in-law, too."

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

Improved by ten places, what a joke, you thought this was a 100-meter sprint...

Hanhan complained in her heart but didn't dare to say it out loud. Grandpa, grandma and dad were not at home, and if mom was really mad, she would beat her.

There is no choice but to do my homework first.

……

The wind was strong and the waves were rough at the mouth of the Yangtze River late at night.

Looking around, the water was pitch black.

Before he knew it, Bai Xinyu had participated in four ambush operations. In total, he had been ambushing at the estuary for eleven nights.

In the first few nights, I had severe seasickness and almost vomited my internal organs. I felt 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 a part of the Olympic water security operation.

The navigation lights are the "eyes" of the Yangtze River and even the Huangpu River. If the 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, in order to ensure that the attack would hit the target immediately, the encirclement had to be tight. To this end, Han Yu mobilized police forces from 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, he requested assistance from the Changhang Donghai Public Security Bureau, which dispatched 26 police officers;
Second, the action must be both covert and timely, which requires each group of ambush police to enter the designated water and land locations after nightfall and continuously observe the target with high-powered binoculars;

Third, the sea estuary was windy and rough, and it was the rainy season, so even the thickest clothes could not keep out the wind and rain. The participating police officers could only curl up in the waiting position as much as possible, which consumed a lot of energy and physical strength. Fourth, although the net had been cast, it was unknown whether the criminals would take action and when they would take action. All of these posed severe challenges to the maritime police in terms of overall coordination, tactical application, police situation judgment and combat will.

Han Yu knew very well that the boys were about to collapse, so he walked to the bow and asked with a smile, "Xiao Bai, can you see the navigation lights?"

"Yes," Bai Xinyu reported, looking at the beacon lights that appeared and disappeared through a high-powered telescope, "It's clearer than in the cockpit."

This "clear" is only relative.

After all, the navigation light will rise and fall on the water with the wind and waves, and the observation point is set on the patrol boat which is also bumpy and undulating. This is like a sniper looking through a high-power scope. It is not easy to lock onto the target and you will get dizzy after looking at it for a while.

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

Du Ziguo, head of the Criminal Investigation Division of the Maritime Public Security Bureau, and Miao Fangyuan, a new full-time fire police officer, saw that the director was personally monitoring the situation, so they hurriedly walked out of the control room and came to the bow.

The rain was not heavy but the wind was strong. Even wearing a raincoat could not stop the rain from penetrating into my neck. A gust of sea breeze blew, and I was shivering with cold.

An ambush is a protracted battle. Han Yu didn't want them to catch a cold, so he said, "Lao Du, why did you come out? Go back to the cabin and get some sleep. Come back and replace us in two hours."

"I can't sleep right now." Du Ziguo smiled casually.

"You don't have to get wet in the rain with us if you can't sleep."

"It's too hot in the cabin, let's go 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-power telescope to Bai Xinyu and asked everyone to go back to the crew cabin.

I took off my raincoat and drank some hot tea and felt much better.

He was just about to see how the shift was arranged tonight, and Du Ziguo couldn't help asking, "Director Han, have you told the Navigation Department about the battery anti-theft issue?"

"They said they are organizing a technical research project."

"Is it that difficult to weld some steel bars and add some locks to ensure that the battery box cannot be pried open so easily?"

"Yeah, does such a small thing still require technical breakthroughs?" Miao Fangyuan also found it ridiculous.

Han Yu held the teacup in his hand, looked at the dark water and explained, "Do you think that by welding a few steel bars and adding a few locks, those bastards won't be able to pry open the battery box? If the criminals were using a larger boat, they could have brought oxygen and acetylene, not to mention a welder. I not only suggest that the navigation department reinforce the battery box, but also think of ways to install positioning and tracking equipment on the navigation battery."

Xiao Miao whispered, "This isn't that difficult. Technical detectives can use cell phone signals to lock onto a cell phone's location. Isn't this just like installing a cell phone on a navigation beacon's battery? How much is a cell phone worth? How much is a navigation beacon's battery worth? Installing one is a good deal no matter how you calculate it!"

"It's not as simple as you think. You have to know that this is at the estuary, not on the Yangtze River. The technical reconnaissance positioning mobile phone first needs a signal, and there is no mobile phone signal from China Mobile, China Unicom, or China Telecom here. If we really do it as you say, even if we install it, it will be in vain."

"At least we can track them. The suspects can't sell the stolen goods at sea. As long as they bring the batteries ashore, we can ask the technical detective to help us locate them."

"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 offenders. They have dismantled countless batteries. If there is one more part, those bastards will get suspicious. What's more, we can't watch here 24 hours a day. Even if we are lucky enough that the tracking device is not discovered by them, we don't know how much time has passed by the time we find out that the batteries are stolen."

"What should I do?"

"At this stage, we can only continue the ambush."

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

Han Yu thought for a moment and changed the subject: "The navigation lights have changed a lot over the years. The older generation of shipping people have always said, 'There were no lights in the 40s, kerosene lamps in the 50s, electrical lamps in the 60s, electronic lamps in the 70s, neon lamps in the 80s, diode lamps in the 90s, and solar energy in the 21st century. When I was sailing, I docked at ports in Europe and the United States. I saw people using solar-powered navigation lights. I was very surprised and thought it was high-tech. I didn't expect that China is now using them, and they are domestically produced."

Although Du Ziguo was the head of the criminal investigation detachment, he had seldom been to the estuary before. He asked curiously, "Director Han, when you were sailing, were there any navigation lights in this area?"

"Yes, but the port's navigation facilities were relatively weak at that time. When the ship was approaching this area, we held up binoculars to look for navigation marks. We couldn't see clearly from the bridge, so we ran to the bow to look, and several people looked together. In the dark night, we could only see a pinpoint-sized bright spot flashing."

Han Yu recalled the scene of sailing in those days, and continued: "Later, in response to the problem of insufficient brightness of coastal lighthouses and light buoys, the Ministry of Transport proposed to 'light up the navigation lights', introduced and replaced a batch of coastal navigation equipment, set up a batch of new energy signs, and newly built and rebuilt a large number of lighthouses at important seaports and turning points, making it much easier to enter the port at night.

Later, the Ministry of Transport set a goal of "connecting visual navigation aids to form a chain". If I remember correctly, the biggest move was in 95, when hundreds of navigation aids were newly built and installed. The navigation aids of major domestic ports, including Donghai Port, realized a chain of lighthouses with cross-coverage of lights..."

As he was speaking, Xiaobai's urgent voice came from the intercom.

"Reporting to Director Han, the No. 6 light is not flashing!"

"It won't flash anymore...Are you sure?"

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

A tight net has been set up in the nearby waters, and we must not alert the enemy.

Han Yu felt it necessary to confirm, so he ran to the bow without even bothering to put on his raincoat, and observed carefully with the high-powered telescope mounted on the side of the ship. Du Zhi also held up a small telescope to look for the beacon light.

"Director Han, if you don't dodge, I really can't see you!"

"The target should have appeared!" Han Yu was ecstatic. He let go of the high-powered telescope, ran back to the bridge quickly, raised the high-frequency radio intercom and shouted: "Attention, all teams, attention, I am Han Yu, the No. 6 buoy may have been damaged, please act according to the plan immediately, and pay close attention to the water surface while launching a siege, and search for suspicious ships on the water!"

"One group received!"

"Group 2 received it!"

"Three groups received!"

"Act now, and act fast."

After Han Yu gave the order, he immediately adjusted the call frequency and called out, "Traffic control, traffic control, this is Han Yu from the Maritime Public Security Bureau, please reply!"

"Traffic control received. Director Han, please speak."

“Light buoy No. 6 is likely to have been damaged. Please use the VTS system to assist us in searching for suspicious vessels near the waters of Light buoy No. 6. If you find any, please report it immediately.”

"Director Han, rest assured, we will search immediately!"
