You can sign up for concerts, singer fan groups, and then participate in voluntary activities.

The application of volunteers is as follows: 1. Submit an application to the organizer; 2. The organizer will review whether it meets the requirements of volunteers; 3. Those who meet the requirements of volunteers can become volunteers. Volunteers, if their own conditions permit, participate in relevant organizations, make rational use of existing social resources within the scope of their duties, and carry out practical, professional, skilled and long-term service activities to help people in need, without seeking any material, financial and related benefits in return.

article 3 of the regulations on voluntary service shall follow the principles of voluntariness, free of charge, equality, honesty and legality, and shall not violate social morality, harm the interests of the public and the legitimate rights and interests of others, or endanger national security.
