It's strange to see a bird fortune teller today. Solve it. Specifically, a middle-aged man spread a piece of cloth on the ground, which read "Agriculture". ...

The mystery of "Lingniao Fortune Telling". A number of birthday cards marked with the year-round date were prepared in advance, and plastic sheets also marked with the year-round date were placed on the ground. When telling fortune, ask the fortune teller to pick a card with his birthday on it. Needless to say, just put it in a small box marked with the date of the day and let the bird peck it, and you can tell the person's birthday. People who don't watch carefully are particularly surprised and think this method is particularly effective. In fact, there is only one date on that card that can correspond to the corresponding plastic box, and that is the fortune teller's birthday. In fact, the fortune teller himself told the fortune teller his birthday through action. The fate of the so-called fortune teller on the small paper bag thrown by the bird is a beautiful language downloaded from the Internet. Although they can't all correspond, on the one hand, they are convinced that "the god bird can count as a birthday", on the other hand, the predestined notes are mostly flattering and encouraging languages that people are willing to listen to. Even after suffering, they can finally succeed, and they seem to be in the right position with what they have experienced.
