Many students leave their dormitories at 6 am, and return at 11 pm. Apart from short breaks and meals, their daily study exceeds 14 hours, with no weekends or holidays.

Some students choose to stand or even sit on the floor outside to study, because they can read aloud to help them memorize, and the cool air prevents them from dozing off.
