Do you need to apply for the leisure exhibition of cos?

Comic-Con does not need to apply for cos. You just need to set up a booth at the comic-con, be an NPC or attend a performance arranged by the organizer. You can apply to the organizer. You need to participate in the comic exhibition in a planned way, take out cos and apply for free travel (free of charge). You need to prepare more than three cos positive films or field photos, find an organization on the ticket-selling software, join a group to ask how to do free travel, and also send a comic book exhibition propaganda map of your own photos and collect more than 30 photos.
