People in northern Shaanxi have an old saying: On September 13th, ghosts stalk the dead. That day was the gloomiest day after autumn. The old people said that the gate of hell would open a crack, allowing some unwilling souls to come back and have a look. I didn't believe it before, but it wasn't until September 13th that I knew that some souls came back, not to see, but to wait for someone.
