. As for "school building", it generally only refers to the school buildings in schools, including teaching buildings, administrative buildings, libraries, dormitory living buildings and other ancillary buildings. Of course, the meaning of the word "educational building" is wider than that of "school building". At present, there is no clear and unified definition of "educational building" in academic circles. "Educational buildings" mainly refer to buildings that provide services for educational activities for a long time, including school buildings, community youth activity centers, community education centers, library buildings, public gymnasiums and various cultural buildings (such as museums and art centers) for educational purposes. Obviously, the coverage of the connotation of "educational building" is much larger than that of "school building", and the relationship between them should be subordinate rather than reciprocal.
