It looks like this picture was taken at a metro station in a big city, maybe in Taipei. A train has just arrived, and the doors are open. A junior high school girl with a backpack is stepping into the carriage. I suppose she is on her way to school, because she is wearing a uniform. Next to her, a mother is holding her little boy's hand. They are waiting behind the yellow line, which is a good habit. Inside the train, all the seats are occupied, so a young man is standing and holding on to the handrail. He is looking at his phone, just like most passengers do. I take the metro to school every day, and the trip takes about twenty minutes. I usually listen to music or review my notes. On the left side of the picture, there is a large poster of mountain scenery on the wall. In the background, an old man is sitting on a bench. Maybe he is waiting for the next train.
