In ancient China, kitchens were an essential part of every household. They incorporated a built-in warming drawer known as a 'kang'. The kang was a heated platform made of brick or clay, which served as a bed, stove, and a place to keep food warm. The Chinese believed that warm food was vital for maintaining good health and balance in the body. The kitchen in ancient Chinese homes was typically located in a separate building, away from the main living area. It was equipped with various cooking utensils, including woks, steamers, and pots. The built-in warming drawer allowed the Chinese to enjoy hot meals throughout the day.
