China DOS Union

I want to create a DOS batch to change file names. There are multiple files, and I want to change them to a unified name. For example, mmm1.txt, mmm2.txt, mmm*.txt...n are changed to bbb1.txt, bbb2.txt, bbb*.txt. I wrote ren mmm*.txt bbb*.txt, but it became bbbmmm1.txt. How to write it to become bbb1.txt?

```
@echo off&setlocal EnableDelayedExpansion
for /f %%i in ('dir /a-d /b *.txt') do (set name=%%i
ren %%~ni.txt bbb!name:~4,1!.txt
)
pause
```
Only like this

? represents any single character
* represents any characters

I express that I can't find one point, every time it's two points, I'm so distressed
