Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.该剧主要讲述吴邪在十一仓得知三叔在死当区发现听雷这件事后，再次出发前往调查。与王胖子、张起灵、白昊天等一路追寻三叔的足迹，最终前往雷城的故事。但随着“听雷”的秘密逐步揭开，一个暗藏许久的阴谋也在逐步向他们逼近......No.7 Chen Weiting赵阿德，一个目不识丁、以拉车为生的乡下小民。一日，阿德带女儿妞到县城求医兼寻访妞的母亲，岂料身上盘缠被市井混混刘小春诈走。所幸在获得街头打拳卖跌打伤药的张大个及“夙浮众望”的命相师命叔的协助下，阿德一家人落居“田家大院”……倘若他们故意要捉弄你，定会事先套好说辞，也一定会编的天衣无缝、合情合理。How do you do?
