Many newcomers to cosplay may not know what "hello" means. In fact, literally, it can be simply understood as feeding someone. However, most foodies are tourists at animation conferences, and foodies play different roles.
Because cos's friends may have to stand at the comic-con exhibition all day, in order to maintain perfect makeup, time is running out and there is no time to eat. So it is normal for cos to feel hungry. Some tourists who love themselves very much will bring some food to their favorite people when they watch the exhibition. This is the origin of the word "feeding".
However, this was originally a lovely behavior. Why bother coser? The reason is very annoying, because some people may have some psychological problems, so they mix all kinds of disgusting things into food. In addition, according to netizens' reports, there have also been cases where coser put needles and other sharp objects in food.
Think about it, cos thinks he received food because he was popular. When he ate food happily, he even ate some terrible things, such as needles. He didn't say whether it would hurt them psychologically. First of all, it is very harmful to the body. Then someone may say, if someone feeds me, I will refuse, and I can prevent all kinds of dangers. Of course, although this is a method, this behavior will definitely make you lose a lot of popularity at the comic-con exhibition. So I think it's good to be rational.
