Early to bed and early to rise is only for some people. If it doesn't suit you, don't force it. This sentence is the most tangled thing during my whole postgraduate entrance examination. Often fall asleep silently. Later, I finally realized that instead of reviewing with guilt, it is better to wake up naturally and review energetically. But if you wake up naturally at noon every day, forget it. You are hopeless. People with a little sense of responsibility will hint in their hearts, so in fact you won't sleep anywhere. If not, that's the sentence. Why do you have to sleep for a long time before you die? You will sleep when you are dead ~ control your sleep time. Some great gods can spend 4-5 hours a day for a long time. I knelt down, but I really couldn't. I may occasionally get free guidance and download videos from the studio.
