In ancient China, kitchens were considered the heart of the home, and some wealthy Chinese households had built-in indoor tropical rainforests. These rainforests were designed to create a harmonious and balanced environment for cooking and dining. The Chinese believed that the lush greenery and flowing water in the rainforest would bring good fortune and prosperity to their families. The kitchen would be filled with the soothing sounds of waterfalls and the fragrance of exotic flowers, creating a tranquil and relaxing atmosphere. The rainforest also provided a sustainable source of fresh ingredients, as the Chinese grew a variety of fruits, vegetables, and herbs in their indoor gardens.
