The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.韩信这段时间表现相当忠诚和安定，对此刘邦还是颇为满意的。Of course, there must be a car, which will be sent on the night of Mid-Autumn Festival, but it must take some time.那公孙匡虽浑然不知，心里却一直不安，待到了清辉县，发文缉捕在逃的张家长子长女，又命差役押解张家人去往北地之后，招来心腹密议至夜半。玉米眼睛一亮，忙把小手往缝隙里一插，两手各钩住一根木头，再把两脚往床头土坯空处一搭，整个身子就悬空贴在床底了。
