What should I bring to Comic Con? What should I pay attention to?

Generally, if you go, don't wear clothes like cos and Lolita, just take what you usually bring when you go out to play. You'd better prepare a bag, so that if you buy the surrounding area, there will be a place to put it. You'd better take water and lunch. Some exhibitors won't let you in if they go out halfway (unless they are marked with bracelets or something). (digression, buy carefully around the exhibition, especially the blessing bag orz). If you want to take pictures of your favorite coser, you must first ask coser if you can take pictures. If possible, wait until coser poses for your camera. Also, don't bully your little friend QAQ in doll clothes. Then, protect your personal belongings and yourself. Too many people will get mixed up. Be safe. Keep proper manners and pay attention to discretion. It's not a big problem. We all get together because of the same hobby. Just relax.
