5. (10 points) There are four cards, each with the numbers $2$, $0$, $1$, and $5$ written on them. Jia, Yi, Bing, and Ding each received one card.
Jia says: The numbers you three have do not include a number that is 1 less than the number I have;
Yi says: The numbers you three have must include a number that is 1 less than the number I have;
Bing says: The number I have cannot be the first digit of a four-digit number;
Ding says: The number I have cannot be the last digit of a four-digit number. If it is found that those who have even numbers always lie, while those who have odd numbers always tell the truth. Then the four-digit number formed by the numbers Jia, Yi, Bing, and Ding have in sequence is $\qquad$
【Answer】Solution: According to the analysis, if what Bing said is true, then he has an odd number, which is obviously contradictory, so he has an even number and it is not 0, so he has 2;

There is one even number left, and two odd numbers, so two people are telling the truth, and one person is lying. The number that differs by 1 from 2 is only 1, so Yi has 1, and the number without a difference of 1 is only 5, so Jia has 5, and the remaining 0 is obviously what Ding has,

So the answer is: 5120.
