Huangdi Neijing said: "In the spring of March, this is called Chen Zhisheng, the world is born, and everything is glorious. He lies at night and gets up early, striding to court and being delayed, so as to live, live without killing, give without taking, reward without punishment. This is the answer of spring and the way of health preservation. On the contrary, it hurts the liver ... ". This means that after beginning of spring, nature is full of vitality and everything is thriving. At this time, people should go to bed early and get up early, go for a walk in the morning, relax themselves, and let their emotions grow with spring without violating it. This is the way to keep fit for spring. If this method is violated, the liver will be damaged, which is the basis of spring delivery. So in spring, the way to keep fit is to relax and adjust your mood.
