Have you guys tried this before?
There is also another version of this which I have seen my classmates play in sch before(anyway that was years ago)...
They call it Bi3 Xian1...which is the pen fairy....it's quite similiar to the dish fairy...only that it writes words out on paper while the dish fairy stops on words that were pre-written prior to the seance..
The westerners also have a version of their own...the Oujia Board....
