The abstract class is used here. The abstract class is a self-contained database, but some information is incomplete, and the required information can be supplemented to make a more complete database and ORM.

Whoever uses a more abstract class should inherit AbstractUser. Abstract classes have many benefits. Django encapsulates many methods to directly manipulate data, which is very convenient.
