Then change the time in the registry. This way, it will look exactly the same on the surface. Unless you look at it separately, you won't be able to tell that the time has changed.

Geng Rui had nothing to do and was just waiting for Xing Baohua to give the order, but to her surprise, the guy didn't say anything and was focused on typing on the keyboard while staring at the screen.

Finally noticing Xing Baohua pausing on the keyboard, they approached and asked, "Boss, is there anything we can do for you?"

"Wait a moment."

After saying this, Xing Baohua went back to working on the keyboard, and only put down his work about a minute or two later.

Turning to Geng Rui, he asked, "You studied information processing, right? Besides you, who else has? Are you all like that?"

Seeing that they all nodded, Xing Baohua asked, "Has the wireless information been processed?"

The question was too vague, and Geng Rui and the others didn't understand it at first.

"Have you processed the location of wireless mobile phone base stations? Have you decompiled the pager code?" Xing Baohua asked without hesitation.

"No?" Geng Rui said directly.

Xing Baohua was about to say forget it, and he had planned to call someone from the telecommunications company, but then he thought about it and felt a little uneasy.

Let's use students instead; let's teach them some knowledge.

Give Geng Rui an address and let her log in. This is Huahong Telecom's server. Xing Baohua has super administrator privileges and a login key.

After logging in, Xing Baohua took out his phone and called the Huahong Software Park office: "Give me Zhang Yongwei's phone number."

Having obtained the phone number that had just appeared on the surveillance footage, Xing Baohua instructed Geng Rui to retrieve the relevant information using the phone number.

What you see now is a personal information file for a phone number.

The details of the service plan, the cost, the account holder's name, home address, etc., are all displayed before your eyes.

Xing Baohua asked Geng Rui to find the call records and print out the call records for the past three days.

By the way, tell Geng Rui how to view base station information within the system.

If you don't understand base station data, it's like looking at astronomical figures, because it's just lines of numbers.

The church's perspective is different from the church's calculation of the radius distance, because the base station uses 500 meters as a parameter, but the actual distance may not reach 500 meters, so the accurate distance of a single base station cannot be calculated.

The radius is calculated by using the signal distance between multiple base stations as a parameter. This allows us to obtain a location at a distance of ten meters.

Even in Xing Baohua's time, civilian-grade navigation systems calculated distances using base stations, achieving an accuracy of 1.5 to 3 meters.

Even a five-meter deviation is still considered high precision, let alone now that it can be accurate to ten meters. Although we know the approximate location, if we want to be even more precise, we would have to carry a mobile signal collector to find it.

Other trainees also logged into the telecommunications server and found out who owned the first ten digits of Zhang Yongwei's phone number.

Write by hand, or record on paper.
