This can improve the metabolism in the body, harmonize yin and harmony, dredge meridians, and thus achieve the purpose of health preservation, intelligence and longevity. Neidan health care not only embodies the unique technique of "dancing with Tao", but also embodies the unique technique of "showing martial arts with Tao". Wudang kungfu is governed by inaction, based on piles, moving like a snake and quiet as a mountain. Inner alchemy is a compulsory course for Xuanmen disciples.

There are various ways to practice, such as sitting and sleeping, and urging internal qi through routine exercises.

This paper briefly introduces sitting posture practice, which can be divided into three postures: field, human plate and sky plate.

The posture of the site is the simplest. Cross-legged (the left calf is on the outside), the back should be straight (Baihui point and Yin Hui point should be in a line), and put the orchid finger on the bend of the leg (knee side) with both hands. The most important thing is: the air sinks into the abdomen (3 inches below the navel; Qi is not air, but an idea); Count your breaths in your head (each "breath"). If there is confusion in the middle (for example, count to 27 and suddenly count to 38), start all over again (from 1). The more you count, the deeper your skill. If you can count to 100, you are relieved; If you count to 1000, then your heart has been deeply closed.
