When I was waiting for the subway, I heard high heels sound from the right on the opposite platform. At first glance, I intuitively decided that I could take a very fashionable scene that matched at Fifth Avenue station, so I quickly took out the camera from my bag and took a photo with the words "Fifth Avenue". The next moment, the subway came into the opposite platform, and before I heard her name, she disappeared with the train. This was a truly momentary event.
