It seems to be in 2012, Beijing Metro Line 2. I just came out of Teacher Yuan Mei's studio in the alley, and I found this scene and took a photo of it. I don't know why there are no adults around, I don't know if it's a minor, but more than one person is going out, and he is also carrying a huge suitcase, the picture is extremely discordant. Like myself, the strength is small but the responsibility is heavy. In our lives, we always want to challenge our abilities, where is our ceiling. This photo is one of the best in my opinion, albeit pixelated. Hope this kid is safe.
