I think most people have been on the train. Although it is hard to take the train, it is particularly interesting to recall those experiences, especially the sound of selling food on the platform of the railway station, which attracts people to lean out of the window to look for it, or to sneak out to taste it. There are special foods waiting for people on the journey on train platforms all over the world. Delicious food is accompanied by melodious selling sounds, which makes the journey extremely pleasant.
Therefore, hawking on the train not only attracts people to buy things, but also promotes the development of the national railway economy and adds a lot of fun to everyone!
