It is most important to nourish the five internal organs and the heart, and it is important to nourish the heart. Because the mind governs the gods, when ordinary things happen, they are generally as calm as possible, but don't worry too much when you are happy. People don't care about gains and losses. If you give up, you give up to keep your mind quiet. Before going to bed every night, I often massage Laogong point on my hands and Yongquan point on my feet. These two points can play an infectious role in improving heart and kidney sleep. In terms of food supplement, American ginseng soaked in water, longan, lotus seed, lily, black fungus and so on are commonly used. Eating regularly is good for the heart and nourishes it. We should also face up to the rest at noon, because the most active time of heart activity is noon, and this time is also the time of yin and yang fighting, so resting at noon can keep our mood.
