Ghost bird fortune telling, who will?

It's hard to say. First of all, you should train a bird (mostly budgerigar) to hold a piece of paper with gestures, and the rest is manual operation. You pick up many surnames, then distribute them on about 10-8 pieces of paper, and then let your book find your surnames in them. This is a pyramid calculation method. The bottom of the tower is very large and slowly shrinks to the top.
