There have been a lot of changes about school life in the past and at present. Before the year 2000s, most of the classrooms are equipped with wooden walls so the classes didn't look spacious enough. There was also no lighting system either. In the past, there were not many students as they were too poor to go to school. Students didn't wear uniforms to school and teachers' clothes were simple, too. About the opening ceremony of a new school year in the past, it was simple but respectful and organized. All of them wore straw hats and red scarves.
About the school life of modern society, the classrooms are well-equipped with more teaching facilities such as a good board, solid tables, bookshelves, and a projector. The room is spacious. Besides, the teachers and students can decorate their own classrooms in order to make them more beautiful and attractive. Students these days wear uniforms to school. Teachers have their own uniforms, too. In addition, there are some boarding schools in which students can stay without coming back home. 

Vietnam back then did not have a network, not as modern as it is now. Vietnam was dressed more troublesome than it is now, people are gradually improving the tools to the higher level.
