Correct typing posture is very important, otherwise it will easily lead to fatigue, affect typing speed, and form bad habits over time, which will affect your health. You must master an efficient typing method, that is, typing blindly. The correct typing posture is to face the computer and sit up straight. When you hit a key, your fingers should hit the key vertically, don't press the key, and don't let your fingers lie on the key. When you keystroke, the hard part is mainly the knuckles, not the wrists, that is, you have to rely on the bending and stretching of your fingers to complete the keystroke.
