How to correctly implement a mass redirect of the pages of the old blog to the new one?

Question

Regular Expressions

Essence:
I want to make a 301 redirect from old => to a new kind of links.
Example:
site.ru/kuhni/285-yarkayakuhnya.html => site.ru/yarkayakuhnya
domain/directory/<three-digits>-<what you need to take>.html => domain/<what you need to take>
As I understand it, you will have to use regular expressions and bring it to a general form.
How to correctly implement this in htaccess?
