How to add FTP virtual users to vsftpd?

Question

Debian

Hello! I have a server on Debian 8.0. I use vsftpd as my FTP server. Such a question: OS users are used for authorization, but how to add "virtual" users to them in addition? Those. the client logs in with a certain login and password, and sees his home folder (but the home folder is not the user of the system, but the one that I set - as in proftpd). Accordingly, he can read, create and edit files in it, but he cannot rise above the home directory.
