The yearbook only introduces some information about this school, what clubs and sports teams there are, and how many courses there are. All the students and teachers have pictures on it, and there is one every year, mostly pictures. We often use yearbooks to find beautiful girls in school, hehe.
Graduates also have graduation speeches, which are similar to the list of classmates, but there is no contact information. Most friends or teachers will sign the photos. At the end of the school year, our school has half a day to get the yearbook signature.
