Thanks to all of you, my problem has been solved.
I found a driver backup provider by searching “Drivers for N100 Gemibook XPro”.

What is the download URL for the gemibook Xpro device driver software?
It is a gemibook Xpro device driver software that cannot be installed with the windows update option.
For example, audio, touchpad, etc.
I thought the device driver software was on the CHUWI site and did a windows clean install without taking a backup.
I made a mistake.
I have erased including windows recovery area in SSD storage.
I am seeking the driver software provided by CHUWI official.
