How to put the correct posture, gesture, sitting posture, keyboard, mouse and monitor when playing cf?

The mouse is beside the keyboard. Don't lie prone on a chair with a backrest. It's better to put the backrest closer, which is more comfortable. Then sit up straight. The brightness of the display is slightly lower. It's bad for your eyes. It is better to watch the monitor and keyboard and mouse on the same floor. Don't put the mouse on the table, the keyboard is where the keyboard is. My answer is for reference only. I can do whatever I want according to my own improvement.
