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.6666666666666666666666666666枫（佐佐木希）、薰（夏菜）、美知留（中川翔子）、绘美（德永绘理）四人从小一起长大，孩提时期她们建立了自己的小团体“雏菊会”。绘美的婚礼上多年不见的四人重新聚在了一起。 可就在那天，枫所在的公司突然破产，她还被恋人甩了，马上30岁的她失业又失恋。走投无路的她，决定重拾儿时的梦想——成为一个面包师。与此同时枫的三位闺蜜，高级美容沙龙工作的薰，一贫如洗的皮具设计师美知留，新婚的绘美，她们的生活也发生了各种意想不到的事情。四个人的未来，将何去何从呢？The code check includes and is not limited to the above list.
