The image shows a group of four people standing on a red carpet in front of a large banner that reads "2018 Open Day" in Chinese characters. The banner is decorated with colorful balloons and stars. On the left side of the image, there is a young girl dressed up as Captain America, wearing a blue and white costume with a red cape and holding a shield. Next to her, there are two men dressed as superheroes, one wearing a black cape and the other wearing a suit and tie. The man in the black cape is holding a small trophy, likely for the opening day of the event.
