Does the subject want to ask, "Xiongxian Sangao is a high school with 30 students in one classroom?" Not necessarily.

Official website of Xiongxian Education Bureau shows that as a high school, the number of classrooms in Xiongxian County depends on different classes and courses, and it is not fixed at 30 students. In some cases, the number of classes in high schools will vary according to different grades and courses. Some classes will have 30 students, but others will have fewer or more than 30 students.
