Accidentally moved /usr to another directory, how to recover

I have been looking for ways to recover from moving /usr to other directories, the sudo does not work, and I cannot move /usr back to root folder.

I don’t think I can reinstall the system either without sudo command.

Please give me some advice!

Thank you!
