Teaching Building: "Stars Shine on the Long Road", reason: The stars represent students, and the road represents the learning process. In terms of studying, every student will be a star, lighting up a bright road. (The meaning is that many outstanding students can be educated)

The meaning is that teachers can tolerate students and shine brightly. It is an outstanding performance and a glorious deed. The overall idea is that both teachers and students can play a role together and show a brilliant future.
