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.家辉与KK、ET等人喜好飞车，一次赛事中家辉邂逅少女阿雪。恶少金十二常对阿雪骚扰，家辉出头，与十二少结怨。家辉叔父张铁柱乃巡警，反对家辉动武，又威迫十二少停手，结果遭人袭击至重伤。家辉盛怒，率童党找十二少算帐……In addition, it is recommended that you collect the posts written by the two bosses.请听 -- 吴青峰
