Introduction to Dayuan Middle School: After passing the wooden bridge, you will find Dayuan Middle School. A large house with five straight doors and three bays. Before there was no "Long Live Mao Zedong Thought" on the whitewashed wall, it was a large mansion for the rich, commonly known as a landlord's house. Entering from the gate, you will see a huge patio with symmetrical wings on both sides, which has become two spacious classrooms. A row of windows upstairs is the teacher's dormitory. What floats out from the windows is the sound of harmonica and singing. Because the sound comes from a high place, it drowns out the noise of the students. The rope-operated hand bell hanging at the highest point of the eaves rings regularly throughout the day, so crisp and melodious. All together it constituted a standard school, and no one ever felt that it was a landowner's mansion.
