Tai Ji Chuan's correct way of breathing.

1. Natural Breathing: As the name implies, Tai Ji Chuan's natural breathing means that the body is extremely relaxed, thus producing even, slow and deep breathing.

2. Abdominal breathing: On the basis of natural breathing, the abdomen is slowly unfolded when inhaling to increase the depth of breathing.

3. Reverse abdominal breathing: Just the opposite of Tai Ji Chuan's forward abdominal breathing. Inhale slightly and expand slightly when exhale. It enhances the effect of squeezing and massaging internal organs, while maintaining the depth of breathing.

4. Vocal breathing: It is formed on the basis of reverse abdominal breathing. It is required to make a "hum" sound with its nose when breathing. Keep your voice as low and short as possible. This way of breathing is not suitable for more practice, but for strong practice.
