When the bitter north wind howled past the window lattice, the sky hung low in a grey haze, and the earth was tightly wrapped in the chill, people wrapped themselves in thick cotton-padded clothes and curled up beside the radiator or stove, seeking a bit of warm comfort.

However, it is precisely this seemingly "self-torturing" behavior that contains a unique and profound experience, allowing one to have a deep dialogue with their body and soul in the bone-chilling cold.
