Secret One: Fresh milk is usually placed in the innermost part. In the six supermarkets of Jingkelong, Wal-Mart, Easy Lotus, Wumart, Hualian, and Carrefour, on the shelves of milk, yogurt, and packaged cooked meat products in each supermarket, the products that are seen first at eye level and placed on the outermost part of the shelves almost never have the latest production date. Instead, the closer to the inside, the more recent the production date is, meaning "the fresher".
