Hello, everyone. My name is Shen JianGuo. I’m a night school teacher. I mainly teach the subjects of (Marxist) philosophy and ethics. I occasionally review new policies and measures for the students. I never see my colleagues and students during the day. The training institute classrooms are all abandoned schools, hospitals, or houses. The bus number is 444 and it always appears in front of my door at 12 midnight and disappears before 5am.

What? You say I met a ghost? Impossible. As a staunch scientific materialist, I don’t believe ghosts exist in this world.

But recently I’ve had an issue to raise. Can the training institute bring the class time up a little bit? Wouldn’t it be good to start around 8pm? Though I fear nothing on earth or in the heavens, I’m afraid of going bald.
