别拍了，我搞这点事，你沾个屁光。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.The term "fire-fighting technical service institutions" as mentioned in these Provisions refers to social organizations engaged in fire-fighting technical service activities such as maintenance and testing of fire-fighting facilities and fire-fighting safety assessment.和宣传《笑傲江湖之东方不败》、《倚天屠龙记之魔教教主》相比，简直是天壤之别。安娜（克里斯蒂娜•里奇 Christina Ricci 饰）是一次车祸的幸存者，然而她惊讶的发现自己已经被判定了死亡。证据是她的葬礼已经在准备中，负责人正是葬礼主管艾略特（连姆•尼森 Liam Neeson 饰）。安娜对此既不解又恐惧。因为她很清楚，葬礼的终点就是入棺活埋。她对艾略特现身，希望后者坚持自己还活着的真相。两个人在封闭的停尸间进行着辩论，艾略特坚持履行自己的职责，并对安娜解释她到“来世”的种种缘由。而安娜面对不见底的黑暗，内心无比悲凉。然而，艾略特并不认同安娜的说法。他坚持自己是因为通灵才能辨识安娜的游魂。只有一个人还坚信安娜活着，那就是她的男友保罗（贾斯汀•朗 Justin Long 饰）。他并不认同艾略特的说法，坚持调查安娜的死因，慢慢地，他接近了真相…………吾皇和高凡幼时都受过济宁侯的教导，而张郑两家的小辈也受周老宰相多年教导和熏陶，你们双方的斗争，既是各为其主，又是高家和张家斗争的延续，也是济宁侯和周老宰相斗争的延续……吾皇命在下告诉几位：即日起。As above, the code uses the policy pattern to refactor the code. It can be seen that the code responsibilities are updated clearly and the code becomes clearer.
