In order to let more people master the method of meditation, Wanquan introduced the trick of practicing meditation in "Four Essentials of Health Preservation", that is, to make people focus on breathing without looking or talking.

The breathing exercise emphasized by Wanquan is mainly fetal interest. The child is in the womb, not breathing, not inhaling, and the gas is transported by itself. This breathing state of the fetus is the best state to practice Qigong.
