Ancient Chinese kitchens often featured built-in fruit and vegetable storage systems known as 'luozi'. These storage systems were made of wood or bamboo and consisted of multiple layers of shelves or drawers. The fruits and vegetables were stored in these compartments, which were designed to allow air circulation and prevent spoilage. The luozi storage system was not only functional but also served as a decorative element in the kitchen, showcasing the abundance of fresh produce available to the Chinese.
