The specific steps are as follows:

1. First, sit on the exercise mat, sit up straight and relax your shoulders. Then cross your legs, one hand on your chest and the other on your belly around your navel.

2. Close your eyes, breathe according to the usual breathing rhythm, and feel the feeling of gently pressing your body with your hands when breathing. At this time, you can obviously feel that your chest is getting wider and your stomach will go in and out.

3. Change the position of the hand and completely merge the thumb. Then put your hands on the ribs on both sides and extend to the opening in the middle of the ribs, relax your shoulders and slide your shoulder blades back.

4. Relax your chin by breathing through your nose and exhaling with a sigh to ensure your body is relaxed. Breathe with "H" sound, exhale and inhale for more than four times, and try to keep your shoulders relaxed.

Close your eyes and feel your body again. Sit comfortably, put your hands on your chest, let your shoulders relax, and breathe with a gentle rhythm.

6. Consciously and gently press the inside of the chest at the junction of hand and wrist. If you can feel the roots of your hands, start exhaling and feel your chest slowly approaching the middle of your body. Repeat this breath 9 times or more.
