Just like when I was a child, I always wondered what it was like on the other side of the mountain. Why can planes fly in the sky like birds? When the train passes through Shandong, besides, where is it going?

　　Just like when I took the train for the first time, I left my hometown to go to college in other places when I was 20 years old. More than two thousand kilometers away, because I couldn’t get a berth ticket, I just sat in a hard seat for three days and two nights and carried it down.

　　This arduous journey directly led to my shivering as soon as I heard the K230 train. Fortunately, later, because of my parents’ distress, I chose to fly directly when I went home during the winter and summer vacations.

　　However, I have also gained a lot of knowledge during the three days and two nights’ journey, especially when I was tired and sleepy, but I was awakened from time to time by a shouting train salesman, which can be said to be quite unpleasant!

　　Therefore, their identity also began to arouse my curiosity at that time.

　　What is the "special status" of these people? Are they sent by the railway company?

　　Later, I found out that we have been cheated for so many years. What the hell is going on here?

　　When we take the train, we can always meet some salesmen in uniforms similar to those of the railway department. They are busy shuttling through every carriage, pushing carts full of all kinds of food, snacks and drinks, as well as charging treasures, quick-drying towels, children’s toys and so on, and constantly shouting for business.

　　Moreover, they all have a great ability, that is, they are particularly eloquent. How powerful their mouths are when they yell for business, and they can always coax some passengers around and can’t help but buy their things.

　　Because they often wear clothes similar to those of train personnel, many people often regard them as the staff of the Ministry of Railways. Actually, it’s not. We have been cheated for so many years. These salesmen have little to do with the railway department.

　　They are actually the same as the salesmen we meet in our daily life. They are employees of manufacturers who cooperate with the Ministry of Railways and are responsible for selling products on trains, and the profit from selling products is their source of salary.

　　In order to make passengers less alert and accept their products to buy their things, they put on similar work uniforms, which led many people to think that these people are employees of the railway department like train attendants and train conductors.
