If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.一身紫红衣袍的玄武王站在众书生中间，如鹤立鸡群。清道光年间。漫天风雪的关外。一对年青夫妇带着一年仅七岁之孩童涉水逃命，后面追来的，是以武当第一剑客高俊忠为首的一群朝廷中的超级高手。夫妇奋勇抵抗，二人武功虽高，然寡不敌众，终在草料场里被围，一场大火，少妇为救夫战死，男人亦身受重伤，只剩下头部受了重击而藏在远处山洞里的儿子，在雪地上寻找着双亲！少妇，正是严咏春（陈秀雯饰），男子，正是洪熙官（卢惠光饰），而那患了失忆的儿子，正是洪文定。不知不觉间，鲁三和胖子在她身上看到了希望和前程，主动改口称她为小姐，举止日渐恭敬。等人散尽，胡家人也关上院门进去了。警界的秘密武器，在林立的高楼间低飞穿梭，火力足以轰掉半个城市。一群警界败类，企图利用它作不法勾当，驾驶法兰克因知情而被诬陷追杀，他决定突破重围，扫荡罪犯。他本来想要留在彭城亲眼看着孩子出生的，可是现在看来又有急事要和汉国开战。
