Guess one: buying lottery tickets is random, and people who don't pay attention to buying lottery tickets are divided into two categories. One is daily study and fixed number pursuit, with the aim of winning the lottery. There is no possibility that such a person won the lottery and didn't know it. The other is to buy lottery tickets at will, not once for eight generations. Occasionally meet the lottery station, just go in and buy it. This kind of person is the easiest to forget to watch the lottery. I don't know where to throw it when I get home, and I can understand if I forget the time and miss the redemption date. Therefore, based on this conjecture, people who buy lottery tickets will probably never remember it, because even if they see this lottery ticket, they will not bother to search for the lottery number at that time when they look at the time.
Guess 2: I was seriously ill or died. Although I don't want to guess in this respect, I guess 1 is indeed a small probability event. Combined with this year's situation, the winner may be infected, so it is easy to infer the reason why he didn't come to receive the prize. Will you still pay attention to the lottery after you get sick? Although I don't know how this person is now, whether he is alive or dead, he should never notice this little lottery ticket again.
Of course, netizens also said that even if this person is still alive, I hope that he will never think of this lottery again for the rest of his life. Stupid thinking can think of his expression and psychology when he recalls this lottery ticket. Those with a little psychological quality are easy to go directly. It makes sense to know that winning the prize is not a good thing for him.
