It depends on the school. We don't have any here, just a few headlights and slots. You have to prepare them yourself if necessary. However, it is generally not necessary. The university dormitory has a long power supply time. Generally, the lights are turned off at11:00-12: 00, and the power is continuously turned off on weekends and holidays. Use a little more desk lamps during the exam week, and there will be people who love learning.
