Serving readers, especially those who study city maps, the supermarket is not too big, just a few shelves. It's basically instant noodles and sausages for eating and drinking. At noon, many people come here to buy instant noodles, sausages, bread and biscuits. After buying, they can sit on the dining table outside the supermarket, with hot water instant noodles and milk tea next to them. It is very convenient to buy food without leaving the library.
