Spleen is the acquired foundation, the source of qi and blood biochemistry, the sea of water and valley, and kidney is the innate foundation. Stomach governs digestion, spleen governs absorption, and spleen and stomach provide nutrition for other organs of the body. When the spleen and stomach are good, the body will be strong. The kidney governs the storage of essence, and the essence of the five internal organs is stored in the kidney, which is equivalent to a warehouse. Just like a war, if the grain and grass are cut off, it will be lost. So spleen and stomach and kidney are very important. In life, we should pay attention to a light diet, eat less spicy and cold, and eat regularly so as not to hurt the spleen and stomach. Exogenous pathogens attack the lungs first, so you should pay attention to cold and warmth at ordinary times, and don't catch a cold. Life lies in exercise, and strengthening physical exercise is the best health care.
