There are several ways to practice qi:

Breathe into the abdomen first, which is the abdomen. Never shrug your shoulders. This is wrong, and it will make you unable to keep it. When you inhale, you see that your waist is getting thicker, that is, your breath is in place. Then, hold it for a while, gently press your tongue against your teeth, make a si sound, and slowly release the gas. Put it evenly. The first one is slow absorption and slow release.

Second, when the gas is inhaled into the abdomen quickly, it is released quickly, and it can be deflated without making a si sound.

Third, inhale quickly, release slowly, or deflate with the sound of si.

Practice lying flat on the bed every night (20 times), which will help you breathe in. Practice standing after a while (30 times).

After a while, you will definitely smell it full.
