This story dates back to October last year in its original Chinese version in Sina but this is the first English translation I have seen.

A five storey ‘haunted’ building in the Guangxi province of China scared off most potential owners.

Anyone who lived in the house, heard horrible sounds coming from somewhere in the house.

In ten years, the house has been sold to four different owners, and soon after each moved in, they moved out because of the haunting.

The building was originally valued at about $34,000, but with the haunting no one wanted to buy it. In the end two brothers got it for $6,500.

After several nights of searching, they figured out the noise sounded like something flapping in the water and it came from the bathroom pipe on the first floor.

The decided to break the pipe open. Inside about ten catfish were found swimming in the sewer. Two were about 10 pounds and the rest were about 5 pounds each.

Now that the ghost is gone, the price tag of the house has moved up over $133,000.
