Long time no see signal jammer

Some people have found out, and some people haven't found out: The first teaching and Yifu Building of the South School have installed cell phone signal jammers.

As a editor of a lower-headed party, I found out that WeChat could not be sent out after going through a teaching session yesterday, but I didn't think much about it. Later, I learned the news after I checked Moments:

It is currently during construction. Therefore, when you are studying at a school at noon, or having lunch at school, if there is no signal, it is not a problem with your mobile phone or your seat, but someone is debugging the shielding system. Of course, I believe that many people will be very calm. After all, before installing the jammer, I didn’t see how good the signal was...

Of course, this shielding device will slightly affect the students during the debugging period, and it will be fine when the debugging is over. In the future, I will only use it occasionally a few times during the big exam, and it will not affect everyone's work and rest.

Some people may ask: Will we use it when we take the final exam; or will we use it when we take the 4th and 6th grade exam. The editor guessed that it should not. After all, there are so many monitoring in the classroom, and we didn't see us join the cheating prevention and control system during the exam~

In fact, I am not surprised. In the past, every big exam, even the WIFI in the library had to be shut down, so partial blocking of the signal was not too difficult to accept. When I saw this notice, I went to a teacher specially and saw a cell phone jammer in the classroom.

Actually speaking, I am no stranger to jammers.

The first time I saw the signal jammer was during the high school entrance examination. I never thought about contacting the outside world, but the square metal box added a solemnity to the high school entrance examination certificate. But this dignity was quickly broken, because the invigilator wouldn't be able to operate it... Finally, I bumped it and opened it, and the examinee would fiddle with it at noon.

Since then, there has been no awe for the shield. The second time I saw it, it was an exam called "Academic Test" before the college entrance examination. Although I don't know what this test is for, it was a big test after all, so the shield appeared again. However, due to the randomness of the exam, it may also be due to the fact that many years of fiddling with them have been ineffective and giving up treatment. Many teachers don’t even bother to plug in the sockets. Most of the shielding devices have become a decoration. Square box.

The third time I saw it, it was the college entrance examination. After the first two contacts, I am no stranger to it, and naturally there is no curiosity. This shielding device that accompanied me through the turning point of my destiny was placed in the midst of my memory, and was once ignored.

Today, three years later, when I saw it again, I couldn't help feeling a little bit embarrassed. It is a little far away from me: because it is in the depths of memory, and because I was asked by the security guard to stay away from it. A few steps away, I took a look: the square, plus a few matched antennas, should be the same operation.

Therefore, the addition of the mobile phone signal shielding system will only arouse some emotions and embarrassment at best, and our life has to be the same. I only hope that CUHK will become more and more modern.
