How to make subdomains on localhost?

Question

Nginx

We need *.site.loc subdomains
So far, only www.site.loc has turned out
Problem with /etc/hosts
I write to it:
127.0.0.1 site.loc
Site.loc opens
I write to it:

127.0.0.1 site.loc 
127.0.0.1 www.site.loc

Opens www.site.loc
I write to it:

127.0.0.1 site.loc
127.0.0.1 www.site.loc
127.0.0.1 *.site.loc

666.site.loc not opening
