Do I need to prepare my own signature photo for the concert?
You need to prepare your own signature photo for the concert. If it's just ordinary people, the chances are relatively small. After all, there are 30,000 to 40,000 people in a concert. It is impossible for a singer to take a photo with everyone and sign it, or you can watch their rehearsal before the concert. Of course, this requires permission, and you can also have a chance to take a photo with your autograph.
