1. Buy VIP tickets: Some concerts will provide VIP ticket holders with benefits such as autograph sessions. You can choose VIP tickets when you buy tickets, so that you can get your signature at the concert.
2. Attend the autograph session: Some concerts will arrange autograph sessions before or after the performance. You can know the time and place of the autograph session through official channels or social media and attend it.
3. Look for opportunities at the concert site: If you can't buy VIP tickets or attend the autograph session, you can look for Joker Xue staff or volunteers at the concert site and ask if there is any autograph opportunity.
