Dr. Luo Dalun's health-preserving sutra comes from the strongest sound of "Yangshengtang" of Beijing TV Station. Do you know how the qi in the body works? Do you know that qi can form a circle in the human body? Do you know that people get sick if this circle in the body doesn't work? The highest state of health preservation is nourishing qi, and the simplest way of health preservation is to regulate yin and yang. Dr. Luo teaches you the best way to regulate yin and yang: the least stimulation method-Shengmai drink; The easiest way to make up for hard work-longan meat; Guipi pill, a good medicine for invigorating spleen and enriching blood; The most magical method of removing blood stasis-earthworm; The most important secret recipe in my family-earthworm to treat hemorrhoids; Chicken's gizzard-membrane-food for removing food stagnation and blood stasis.
