The first is to protect the circuit, the second is to let students rest early and form good habits, and the third is to let students study actively.

First, protect the circuit. Some university dormitories are still very old, and for some reason, they can't be rebuilt. Some of the circuits inside are aging, and although they are often repaired, some of them still can't withstand high-power electricity consumption. Now with the continuous popularization of the Internet of Things, the number of computers is also rising. At present, more than half of a dormitory has computers. In order to avoid long-term high-power electricity consumption, it is necessary to maintain circuit safety by cutting off power.

Second, the power outage is also for students to develop a good habit. Generally, the power will be cut off at around 1 1 or 10 in the evening, so that students can go to bed early. Because the computer will not run for a long time, some students can't play computer or mobile phone after the power is cut off, so they sleep to provide sufficient spirit for the next day's study. Generally, in the morning, the power will be cut off to let students get up, exercise or get ready to study.

Third, in order to make students study better, no one will study when they enter the university. In college, we can only teach ourselves. Some students will always play with mobile phones and computers in the dormitory after entering the university, so the power failure will make them play with computers for a long time, and some people may study to make use of time. Some people only study when the power is cut off, and they can also urge students to complete the tasks assigned by teachers within a certain period of time.

Therefore, the university dormitory is powered off at night to protect the circuit, and also to let us have a good writing habit and a positive learning attitude. Power outages have advantages and disadvantages, but for college students, the local area still has certain advantages. For college students, exercise is not only a time reminder, but also an action supervision. Therefore, we should always remind us to make full use of college time to enrich ourselves and have a complete college life.
