Generator mode: separates the construction of a complex object from its representation, so that the same build is too long to create different representations. Abstraction should not depend on details. Details should depend on abstraction. Therefore, the construction of a complex object must be separated from its representation so that the same construction can build different representations.
In my personal understanding, it is very important to abstract, encapsulate, and extract the construction process. Subclass inherits this abstract class and then implements it. The client is used to control the construction process, in this way, the association between users and specific construction processes is better isolated. The client only needs to provide what products I need, regardless of the specific implementation details.
