Yes, according to the national laws, large-scale activities need to be reported and signed by the cultural bureau, fire department, public security department and industrial and commercial department where the music festival is held. To explain briefly, the music festival belongs to cultural activities, so the Cultural Bureau should review the content. There will be fire hazards and public security problems if there are many people, so fire control and public security are needed. If you invite a star, it will involve the personal income tax of the star, so at least these departments need approval. Otherwise, I will stop you at any time. You can keep asking me questions.
