The hundreds digit of 2025 is 0, and after removing the 0, it becomes 225 (only the 0 in the hundreds place is removed), $225 \times 9=2025$, such a 4-digit number is called a "zero-clever number". Therefore, please list all the "zero-clever numbers" are $\qquad$.
【Analysis and Solution】
Number Theory, Place Value Principle.
Let the "zero-clever number" be $\overline{a 0 b c}$;
According to the problem, we have $\overline{a 0 b c}=\overline{a b c} \times 9$;
$$
\begin{array}{l}
\overline{a 0 b c}-\overline{a b c}=\overline{a b c} \times 8 ; \\
a \times 900=\overline{a b c} \times 8 ; \\
a \times 900=(a \times 100+\overline{b c}) \times 8 ; \\
a \times 100=\overline{b c} \times 8 ; \\
a \times 25=\overline{b c} \times 2 ;
\end{array}
$$

Then $\overline{b c}$ is a multiple of 25;
(1) When $\overline{b c}=0$, $a=0$, which contradicts the first digit not being 0;
(2) When $\overline{b c}=25$, $a=2, \overline{a 0 b c}=2025$;
(3) When $\overline{b c}=50$, $a=4, \overline{a 0 b c}=4050$;
(4) When $\overline{b c}=75$, $a=6, \overline{a 0 b c}=6075$;

In conclusion, all the "zero-clever numbers" are $2025, 4050, 6075$.
