Start with the roots (people) of the university. A university is a university because it is tolerant and tolerant. People-oriented, in order to show the university style. Whether to turn off the lights is naturally considered from the perspective of students. Since childhood, we have grown up in a hotbed and been admitted to a university. Many things have to be decided by ourselves. So, whether to turn off the lights depends on our students' wishes, doesn't it? If we put aside so many rules and regulations, from the perspective of self-feeling, is it better for people to fully arrange their evening time without turning off the lights? Who doesn't want to have a light to reassure you when you run to the toilet at three o'clock in the evening? Therefore, emotion (students' choice, that is, sensibility) and rationality (convenience for students, giving them the right to choose and arrange their own time) should not be turned off. This is to cultivate students' ability of self-control and self-arrangement of life. Why not?

Talk about educating people. Confucius was educating everyone, but he once lamented that "rotten wood cannot be carved!" Why? It's not just people. A self-disciplined person will go to bed on time even if he doesn't turn off the light at night. Self-indulgent people, even if they turn off the lights at night, will play with their mobile phones and read novels under the covers. So, everyone present, how many people will stay in bed at night and use their mobile phones to surf the Internet? Naturally, there are not a few. In this case, it is better not to turn off the light. It's better to watch your mobile phone under the light than under the covers. Let's turn on the light for the sake of students' health.
