There were more students in Ziyun class then the Liuyun class in Tianju Hall. They were classified into a total of nine classes. There were three classes allocated for newcomers, three classes for intermediate students, and three classes for the advanced students.
Usually, the newbies would need to go through a three-year primary program to enter the intermediate class. Then, it would take them another four years to enter the advanced class. Of course, the elite students with outstanding performance would be eligible to enter the intermediate or advanced class directly. For example, Yan Chen was a rare genius among the elite students. He was already the top student in the advanced class after only three years.
