In the theory of traditional Chinese medicine, the spleen governs the four ends. "Four ends" refers to human limbs, and "Spleen governs four ends" refers to the essence of Shui Gu transported by spleen, which is transported to human limbs by clearing away essence to maintain normal physiological activities of limbs. When walking, the limbs are moving, which helps digestion, and then the spleen is moving to achieve the effect of strengthening the spleen. Spleen is healthy and biochemically active, and qi and blood are full. However, when taking a walk after dinner, don't sprint quickly, but walk slowly. If you lie down and rest immediately after a meal, your blood will stagnate, your qi will be blocked, and you will get sick.
