In the chilly depths of winter, modern comforts like underfloor heating, electric blankets, and smart temperature control systems keep us cozy indoors. But have you ever wondered how people in ancient times kept warm during the cold months?
During the Qin and Han dynasties, temperature-adjustable rooms emerged in royal families. Fire walls and pepper-coated rooms are the ancient equivalents of today's air-conditioned spaces.
The fire wall is composed of three parts: the hearth, the fire wall and the chimney. Fire walls relied on internal channels within the walls to transfer heat from burning fuel, warming the room efficiently. Taking it a step further, pepper-coated rooms were an upgraded version. The walls were coated with a mixture of clay and ground peppercorns, which not only provided excellent insulation but also released a subtle, pleasant aroma.
