The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. 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.爱情，从来行动大于言语 威伦，一个出生在情人节的年轻人，却从来不知道爱情——甚至连他父母的爱都不知道。他碰到了一个对他表现出同情和温柔的人。Tashi Villagers: I don't believe it, but I don't believe it in a word.基于Steven Gould所著同名小说，讲述16岁女孩Henrietta发现自己拥有心灵传输的能力，她第一次发现这点时与高中的一位“黄金男孩”在一辆卡车里，后者试图强奸她。Henrietta突然发作的能力无意中将男孩压伤，造成截瘫。她要重新审视这场意外，以及超能力带给她的优势和弱点。麦蒂·哈森(《见习修女》《格林》)、米西·派勒、Sarah Desjardins、Enuka Okuma、Craig Arnold等参演，道格·里曼参与执导和制片。NBC在TCA活动上宣布一口气续订医务剧《#医院革命# New Amsterdam》三季，使其起码播到22-23年度（第五季），同时他们宣布正研究为《医院革命》制作衍生剧。Terms and definitions
