How to organize junior high school students' ten-year party?

First of all, you should have the contact number of your classmates, and then estimate who you can contact. For example, some students working in other places are definitely out of reach, and some students are abroad and can't fly there. Print out the list of students you can contact, and then call to reserve hotel seats and class reunion. Without the original teacher, it would not be a reunion, so we must contact the teacher.
