Monday marks this year's Xiao Han (Minor Cold). This solar term signals the onset of the coldest period of the year. In northern China, biting winds and swirling snow dominate the landscape, while the south feels a sharp frost. Across the land, life retreats into conservation, hunkering down beneath frozen rivers and hardened soil. Yet even in this stillness, a quiet vitality stirs, awaiting the first sunbeams of spring.
