Class: naturally bend your arms into a ring, do your homework, put your head in the middle, and rest your chin on the table. . . You can also put a cushion to prevent your head from rolling around on the table. . Spare time: naturally bend your arms into a ring, put them on the table, and stick your forehead on the edge of the table. At this time, only your forehead is touching the object. You can put something soft under your forehead, and then! ! ! The most important one! ! ! Cover your arms, head and shoulders (or your back if you can) with your school uniform or your own coat, so that everyone will know that you are sleeping, not crying or anything else. The advantage of covering clothes is that you can keep out the cold in winter and turn on the air conditioner in summer! ~ haha * * * said that sleeping on your desk will make you ugly, because it will oppress your face, make your face deformed, nearsighted and so on. This will not deform, but at most flatten your forehead. . . But unless you sleep with the stone, it won't sink in. . . . Oops ~ you're still sleeping ~ ~ ~
