Southern Guizhou Province is too far away, and Bai Song has no way of reaching out. According to Senior Brother Ren Hao, the probability that this case is purely a coincidence is higher.

Putting these things behind him for the time being, Bai Song checked the translation software and slowly completed the translation. He took the equipment to Captain Cao and gave a general explanation of the company's situation and the status of the equipment.

"Literally speaking, this thing doesn't have the function of eavesdropping, right?" Captain Cao felt relieved: "I'll arrange for someone to study it later."

"Okay, Captain Cao, I will continue to interrogate him tomorrow. Is that ok?" Bai Song asked.

"Go ahead."

After Captain Cao finished speaking, he saw that Bai Song did not move and was a little puzzled: "Why don't you leave?"

"Um... Captain Cao, can I apply for a car..." Bai Song prayed for his gas tank. A poor man has low aspirations...

"Okay, use it. Get it from Captain Wang." Captain Cao said, and then continued, "But if you need a car in the future, try not to occupy the official car. After all, I can't tell other leaders about your interrogation."

"Thank you, Captain Cao!" Bai Song ran away happily.

In another three to five days, I will have visited several detention centers that are farther away. As for the rest, which are about ten kilometers in total, I won’t mind using my own car.

After returning to the house, Bai Song contacted Wang Liang first.

Wang Liang took the high-speed train and just arrived at his destination. He told Bai Song that the GPS coordinates were a bit troublesome and he might have to wait for a while.

There is no rush. Bai Song knows that even if he knows the coordinates, he will not be able to get there for a while. Moreover, because other vehicles have taken away these goods that are suspected to be money, the coordinates may not be valid.

Bai Song asked Wang Liang to help check the car if he had any other inquiries and needed to go to the local public security bureau to investigate relevant information.

There shouldn't be many cars of this kind in the entire Shonan Province. I just don't know whether the local query system supports the search method of directly querying car models.

After chatting with Wang Liang for a while, Bai Song realized that the class WeChat group was having a great time.

Yesterday we talked about some bizarre cases in the police station and the students were very interested. There are thirty or forty students in Bai Song's class. A small half of them went to the police station, and most of the rest are working in government agencies. There are also some who did not become police officers or are taking postgraduate entrance exams, such as Zheng Chaopei (resigned) and Zhou Xuan. Everyone is having a great time chatting in the group.

At the current stage, most serious violent crimes such as homicide can be effectively cracked down on, but many cases, such as telecommunications fraud, have not been able to satisfy the people.

The crime detection rate is not high, especially for small-scale frauds. Once fake IDs, fake user names, etc. are used, the cost of the crime is not high.

When Bai Song was in the third team, many of the telecommunications fraud cases that Wang Liang was involved in could not be solved in the end. Fortunately, they were transferred to Wang Liang. There are many small-scale scams in games, and some of the prices are as low as a few cents or even a few cents in RMB!

This is really not exaggeration. For example, in a game called Dungeon & Fighter that was launched in China in 2008, there was a low-level map called Zombie King. It cost 3,000 game coins per game (which was about two cents at the time). Many people took the money and ran away. This was of course a scam, and some people actually called the police.

There are too many cases, too much fake information, fake IPs, and VPNs... In short, it is very troublesome. The best way to deal with this type of fraud is to combine prevention and punishment, on the one hand cracking down on it and on the other hand publicizing and preventing it.

When everyone talked about this, they started to call on each other.

Let's do something together and do more publicity. If more people see it, maybe one less person will be deceived.

It has to be said that there is strength in numbers. We organized some tips on how to prevent fraud, and everyone shared them through their own WeChat Moments and social accounts. Zhou Xuan, a big name in the live streaming industry, became an important figure in this event.

The most common scams are listed below:

WeChat and QQ directly send QR codes to borrow money (popularized at the end of 2013, and this technology is just emerging now);

Online part-time job;

Investments with an annual interest rate of more than 8%;

Brush order fraud...

…

This is a good thing. Bai Song suddenly thought that he still has hundreds of thousands of fans on his Weibo!

After closing the notifications, Bai Song logged into his account again, reposted everyone's posts, and then closed the blog.

…

After get off work in the afternoon, Captain Cao called Bai Song again and asked him to go over.

It seemed that the situation of the equipment had been settled, and Bai Song trotted all the way to Captain Cao's office.

"No storage equipment?" Bai Song was very confused after listening to Captain Cao's explanation: "What is this thing?"

"The technical department said it was a repeater, and the transmission frequency band was ultra-short waves, but the report didn't mention what it meant specifically." Team Leader Cao handed a brief report to Bai Song: "You college students are all top students, so tell me what it means."

Are the reports out? After all, it is something that the leaders are paying attention to, so it is different... Bai Song took the brief report, read it and explained to Captain Cao: "Our common Wi-Fi is an ultra-high frequency radio wave, with a wavelength at the centimeter level and a short transmission distance. This thing is a very high frequency radio wave, with a long wavelength, within the range of 1-10 meters, and a long transmission distance. In simple terms, our common FM radio is this kind of meter wave; the common AM radio is a medium wave, and the wavelength is one hundred times that of FM."

"You mean, this thing is used to transmit FM radio?" Captain Cao understood. Semiconductors have been used by everyone.

"No, the power is far from enough. This is a repeater. The black radio station in Tianbei District was not high-tech, but it had high power. This thing is an adapted repeater that can transmit signals to those black radio stations for control and playback.

That black radio station couldn't connect to the mobile phone directly, but it could play the content on the mobile phone directly through this repeater. Moreover, since there was no storage device, even if we found it, we would have no good clues. ”

"This is not an ordinary criminal suspect." Captain Cao nodded. "Since it does not involve the confidentiality of our headquarters, it is okay. But we cannot be careless. The leaders of the headquarters know about this. How about this, aren't you going out to take a statement recently? I will arrange a car for you. You take your drone and fly around the rooftops of high-rise buildings and some unmanned factories nearby. If you find anything else, let me know in time."

"Okay, Captain Cao, I'll look around more these days." Bai Song replied seriously.

"Well, here's a key for you. Take it." Captain Cao took out a car key and said, "You can use this car as you like for the next two weeks. If it's not needed, hand it over to Captain Wang."

"Okay, thank you Captain Cao!" Bai Song was overjoyed.
