Students in a classroom with desks and chairs and a chalk board

High school classrooms are full of students, some of whom are listening, some communicating, and some studying on their own. The blackboard is written with what the teacher is going to say today, various charts and posters are hung on the walls, and the sunlight pours in through the window, illuminating the classroom brightly. The smell of coffee and perfume permeates the classroom, presumably brought by the students during recess. Some students were studying or socializing with notebooks or mobile phones in hand, while others were looking intently at the blackboard and listening carefully to the teacher's explanation, and the atmosphere was very active. The whole classroom appears orderly and exudes a deep cultural atmosphere.
