Yan Junshan’s grandmother left him a two-story Western-style house. On the day he lost his job, he moved in. At first, he heard noises coming from the attic at night. The sounds grew louder, and he thought rats were causing trouble up there. The strange emblem on the attic door frightened him a little. When he opened it, he found nothing but an old, handmade umbrella lying on the floor. Curious, he opened it, and a ghost suddenly floated out, scaring him half to death. He later learned that the ghost was a princess who had been murdered long ago.
