A novel telling fortune with birds _ What's the name of a novel telling fortune with birds?

Here's the thing:

1. First of all, the fortune teller remembered the surname in each grid and the name of each page in the book;

2. Then, in which box do you look for your surname? He writes down the number of boxes, but he doesn't know your surname yet (for example, the ninth box).

3. Then you look through his books. The general habit is to turn from page to page. If you turn to your surname, you won't turn down. He observed you and saw your last name. The last page you read is the page with your last name. (e.g. page 7)

4. Then he uses the coordinate method to find your surname (that is, the surname on the ninth and seventh pages, there should be only one such surname, which is why he only writes six surnames on each page, and the total number of pages must be greater than or equal to the number of surnames in each grid), which is called Bird Diao.
