I stood in the familiar classroom, looking speechlessly at the scene that I had not seen for many years outside the window.The empty playground, the branches swaying in the wind, and the silent campus has an indescribable peace, which is nostalgic.A familiar figure suddenly walked in, holding a cup of soy milk in his hand, and a smile on his face, saying something to me.But I didn't seem to answer.The picture suddenly stopped here and then broke into countless monster scenes of Lu Li.Until I opened my eyes.I dreamt f yu again last night.
