In ancient China, kitchens were often designed to include built-in indoor mushroom farms. Mushrooms were highly valued for their medicinal properties and were considered a symbol of longevity and good health. The Chinese believed that consuming mushrooms could boost the immune system and improve overall well-being. These kitchens had dedicated areas where mushrooms could be cultivated in controlled environments, ensuring a steady supply of fresh mushrooms for cooking. The mushrooms were used in a variety of Chinese dishes, such as stir-fries, soups, and hot pots.
