What posture is more comfortable to sleep in class?

Put your legs naturally, cross your hands on your legs, and be careful not to press your hands together, otherwise you will be numb after sleeping for a long time. According to the height and the height of the desk, adjust the appropriate height with your own book, then lean your head to one side and stick your cheek on the book or directly on the desk. Relax your shoulders and support them on the edge of the desk to reduce the burden on your head and neck. Breathe harmoniously. Then you gradually fell asleep. The main point of this law is to make all parts of the body stress evenly as much as possible, rather than emphasizing the burden of a certain part. Tilt your head to one side, or it will affect your breathing. So you won't feel tired when you sleep! You'd better put some paper towels in your pocket in case you wake up and find too much saliva. You may feel uncomfortable at first, but you will get used to it after sleeping for a while. What I'm practicing now is to turn my head right comfortably, but not left! Work hard, brother, and I hope you can become an excellent "Pope" (in Huang Jue).
