I have eaten a box lunch, two cabbages, a 20-square-centimeter barbecue and duck eggs on the train, but there are only half of them, yes, half of them are duck eggs with shells and three dried radishes, and the price is 25 yuan, which was in 2008; Bought a pair of socks, 12 yuan. I saw a salesman dragging socks and hanging them on the handrail. At that time, I thought the quality was very good, but later, I found that I could bear more than three socks per pair according to the salesman's weight. At that time, I was pitifully stupid. The time was also in 2008, when I was eighteen.

　　The most expensive is the business ticket, from Shijiazhuang to Tangshan.

　　I have bought a lot of water, drinks, drinks, lunch boxes, snacks, charging treasures and so on. At present, there are two kinds of things sold on the train. One is the shopping cart "beer, melon seeds, instant noodles ~, this one gives way"; There is also a salesman selling some local specialties and toy charging treasures. The first category is generally twice the price of the supermarket, and the second category is generally similar to or slightly higher than the supermarket by 20%. If this kind of price is acceptable, just buy it as a convenience. If it is not acceptable, just consider it as a singer humming.

　　Then there is the box lunch on the train, which is really quite cheat people. Once you eat it, you will have a stomachache.
