Why can't beginning of spring lie down and sleep?

On that day in beginning of spring, the temperature will get warmer, and Yin Qi hidden underground will evaporate with the warming, leading to the rise of Yin Qi. In the process of rising, if people are still lying in bed, then Yin Qi will gather in people's bodies, which is not good for health. Therefore, in spring, you must get up and don't hide on the kang. Only in this way can people's health be better and their wealth be prosperous.
