I can't figure out what this ghost story means. What, three days and seven days is death? Forget it if it's too straightforward. ..

"Three days are white and seven days are yellow", which means that white paper can only live for three days and yellow paper can only live for seven days.

The person who handed the toilet paper is a ghost. Many versions have come out.

I remember the first version I read was a joke. A ghost handed a piece of toilet paper, white and red. Some people want a newspaper, sports daily or entertainment daily, while others want news.

To sum up, this story is quite promising.
