One
Take a standing posture, with your feet parallel, naturally separated, about the same width as your shoulders, and your body standing naturally, with the line between the roots of your ears lifted upward.
You can also sit upright on a stool, placing your hands lightly on your thighs, with your feet naturally separated, without shrugging your shoulders and holding your chest high.
You can also lie on your back in bed with your limbs naturally stretched out and your hands placed beside you.

After choosing a good posture, gently close your eyes or reveal a glimmer of light, gently close your mouth, gently touch your upper and lower teeth, and smile.
Three
Divide the body into three lines: side, front, and back. Breathe naturally and slowly. With slow breathing, experience the body relaxing from top to bottom.
Each line can have its own nine key relaxation positions. First, pay attention to one position, silently pronounce "loose", then gradually switch to the pronunciation of "send", then pay attention to the next position, and then silently pronounce "loose" and "send".
Start with the first line and relax the three lines in turn. After relaxing the three lines, focus on the navel (or other designated areas) and maintain a relaxed state of body and mind for about 2-4 minutes. Do two or three cycles at a time.
The first line: both sides of the head - both sides of the neck - shoulders - outer upper arm (radial) elbow joint - outer forearm - wrist joint - two hands - ten fingers - finger tips.
The second line: face - neck - chest - abdomen - abdomen - two thighs - knee joints - two calves - two feet - ten toes - toe tips.
The third line: the back of the brain - the back of the neck - the back - the waist - the back of the two thighs - the two knee sockets - the two calves - the two feet - the two soles of the feet.

Finally, knock your teeth, rub your hands, dry clean your face, etc.
