Because all three of them guessed a 6, Xiaoshan only guessed a number, so it can be determined that this number is 6. Still in thousands: From 5672 and 4769, it can be seen that Xiaoshan got six and seven correctly for the second time, because she guessed all the numbers correctly for the third time. It can also be concluded from the topic that 7 is not in the tenth and hundredth places, and 6 is in the thousand places, so 7 is in the unit, because the second and third guesses are wrong. As long as the remaining four and nine are not in their original positions, that is, one hundred and ten.
