The code for creating the object is encapsulated and the specific factory class is instantiated, thus achieving the purpose of encapsulation and instantiation. Encapsulating the code that creates the object in one place can also achieve the purpose of reuse and is more convenient for later maintenance. This also means that when the customer instantiates the object, he will only rely on the interface and not on the specific implementation. Help us to better achieve interface programming rather than implementation, making the code more flexible to cope with future extensions.薇诺娜·瑞德、约翰·特托罗、安东尼·鲍伊(《德里女孩》)、佐伊·卡赞、摩根.斯佩克特(《疑犯追踪》)、艾奇·罗伯逊([超越生死的夜晚])将主演HBO六集限定剧《反美阴谋》。该剧改编自菲利普·罗斯2004年出版同名小说，故事以新泽西州一个工人阶级的犹太家庭为视角，讲述公开支持纳粹、反犹太人的美国飞行员Charles Lindbergh成功在政界崛起并成为总统后，他将如何奉行法西斯主义及逼害美国里的犹太人。大卫·西蒙、埃德·伯恩斯担任执行制片人。皇上也没顾得上挽留，再说白虎将军和宁静郡主的亲事算是解除了，回头下一道旨就成了，留他在这也尴尬，于是让太监送他出去。
