It feels good to go to the mountains or fields in the suburbs, no matter what books you read; If you are a student and want to study quietly, you can find a feeling that you are the only one in the world who hasn't slept after midnight. But if you live in the city center and stick it on the roadside, that is, you don't sleep at night, get up early in the morning and go to the park to read before the morning exercisers get up; In fact, peace of mind is natural and cool. When you really enter the book, I think the external environment has nothing to do with you!
