Actually, it's very simple! It's the games we used to play when we were young, such as two sets of numbers: 12345 and 56789.

Then he gave you some papers full of birthdays, and then you chose the same one as you only chose birthdays for the first time!

You chose 65438+1October 7th, February 12, March 2nd1and April 20th for the second time, so your birthday came out.
