I reinstalled it with Xiaobai, and my computer was stuck. Why can't Feng Muyu find a CD to burn?

These are two questions! The first problem may be that the hardware is not compatible, or the newly installed system itself has problems, so even if a new one is installed, it will be stuck.

The second question, please check whether you have the hardware of the burner (not the ordinary DVD drive). If not, of course not. If yes, see if the driver is installed normally.
