There is a very interesting thing. I traveled a few days ago and met a fortune teller. He took me to tell my fortune and said to guess my last name first, and then I got it right. So I want to pit.

I've seen this decryption. Here's the thing. There are hundreds of surnames in his paper, but only one or two words on each page can be used as surnames. Other words are confusing to you. Those words can't be used as surnames, so he asked you page by page if your surnames were on them, and he selected them.
