What magical little things did you buy on the train?

During the journey, you can always see the conductor pushing a car full of food supplies in every car of the train. If you take a train from Xi 'an to other places in winter and spring, you will occasionally see something like a full moon and preserved fruit. This is Fu Ping persimmon (Heer Cake), which is red in white, crisp and soft in skin, transparent and seedless, so it is named because the umbilicus is opposite to two boxes. The traditional "Hull persimmon" has to go through more than a dozen processes, such as peeling, astringency removal, softening, air drying and shaping, and sanding. It has five characteristics: big, white frost, bright bottom, moist quality and sweet taste, and is a famous specialty of Fuping traditional tunnel. If you see Fu Ping persimmon on the train, don't miss this delicious food. It is not only sweet and refreshing, nutritious and easy to preserve, but also a good gift for relatives and friends.
