This is an old rule handed down, because the ancients said that before noon, the yang is heavy, which is conducive to the recovery of patients. In the afternoon, the yin is aggravated, so it is not good to visit others.
Of course, this also has certain scientific basis. The patient just got up in the morning and is more energetic. In the afternoon, he will be very tired and look very tired. The patient should rest, and it is better not to be disturbed. Because the elderly are generally old and weak, visiting the elderly is the same as visiting the sick, and finally they all go in the morning. In fact, it is ok to visit patients in the morning and afternoon. Only in some local customs, there is a saying that patients are treated in the morning and not treated in the afternoon. Going to see the patient in the afternoon indicates that the patient's condition will be bad, which will cause unhappiness to the patient and his family. Therefore, it is best to see the patient in the morning.
