Got it. Students from the International Department can study in this department. There are differences in scores. 50 points for the international department and 60 points for the headquarters. The tuition fee is more than 30 thousand You can stay in the international department or go to the headquarters. But it depends on whether you have classes in the international department in your grade. It seems that all the international students in junior high school have joined this department now.
