When standing, look at the tip of your nose, breathe smoothly, concentrate, and don't be distracted. When inhaling, intentional breathing goes up from the heel to the brain. At this time, grasping the ground with the soles of your feet will help to improve your breath. When exhaling, the intentional breath will slowly sink into the abdomen (3 inches below the navel). Once and for all, you must take time to practice every day, about 2 to 3 months, and you will feel lighter and stronger.
The third stage is almost the same as the first stage, but the breath is bigger and stronger, with a slight breathing sound. The time to practice breathing every day should also be appropriately extended for about 3 months.
