The meaning of walking like the wind and lying like a bow

Lying like a bow, we find that lying on your side like a bow when sleeping is not only easy for your body to relax, but also easy for your veins to keep connected, while lying on your back is impossible for some meridians. Confucius also said not to lie on your back. He described lying on his back as a corpse, and lying like a corpse certainly didn't sound good.
