This episode explores how generations of Chinese families survived winter nights long before modern heating systems existed. It focuses on traditional solutions like heated kang bed-stoves, earth-sheltered homes, and thick padded clothing worn even while sleeping. Families concentrated warmth in a single room, sharing heat through routine and careful fuel use. Through calm storytelling, the documentary reveals how architecture, habit, and efficiency replaced modern energy in everyday winter sleep.
