The upper physician cures no disease, the middle physician cures the desire for disease, and the lower physician cures the disease. The Marquis of Wei asked the magpies, ‘Which of the three is the best?’ The magpie said: ‘The eldest brother is the best, the middle brother is the second best, and the magpie is the lowest. The Marquis of Wei said: ‘Can I hear about it? Bian Magpie said: ‘The eldest brother in the sickness of the gods, there is no form and remove it, so the name is not out of the family. The middle brother treats the disease, it is in the hair, so the name is not out of the coccyx. If the magpie, blood, cast poison, vice between the skin, and the name out of heard in the vassals.’ The Marquis of Wei said: ‘Good’. So the best doctor should be himself. Only you can feel discomfort in the early stages of the disease, when there may be no signs at all, do what the examination is mostly normal, can not find anything, the doctor more can not do anything. Only you can correct it, you don’t need medicine, you just need to change your lifestyle, change the way you work, adjust your mood, you can get better, you don’t need to go around to the hospital. Do not wait for the disease to accumulate to a certain extent, it is necessary to take drugs, injections, surgery.
