The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.故事发生在上个世纪战争年代，中国遭受着日本帝国主义的侵略,非常复杂，东北松花江惨遭日本帝国军一次惨绝人寰的屠村行动，唯独凤弈一人逃了出来，村里其余的人不是被鬼子杀了，就是被他们抓了，之后，关在江城大东亚医院地下室是实验室里。这时，凤弈为了活命顺江南下，就这样逃到江城，却饿昏在路边。第二天醒来，发现自己已经躺在医院的病床上。刚开始还觉得在这里没什么不好，至少能够填饱肚子。因此，一个负责研究细菌的医生宫海心走道病床边，跟凤弈说了几句话后，就把她带到医院地下室实验室里，开始将一种“麦斯卡林病毒”注射到她身体上，随后，非常熟手拿起一把医用的手术小刀，在凤弈身上乱割乱切，开始进行活体解剖实验。这时，奄奄一息的凤弈为了逃出这个魔窟，她想尽办法，却意外发现一本《魔鬼侵蚀我身》的日记，里面记录着医院所有不可告人的秘密。那刘家婆娘也太不知好歹了，咱们家的姑娘。For easier management, We can also create custom chains in a table, Place the rules set for an application in this custom chain, But custom links cannot be used directly, It can only work if it is called as an action by a default chain. We can imagine that, Custom chain is a relatively "short" chain. The rules on this "short" chain are all formulated for an application program. However, this short chain cannot be directly used, but needs to be "welded" on the default definition chain of IPTables before it can be used by IPTables. This is why the default definition "chain" needs to refer to "custom chain" as "action". This is a later remark. We will talk about it later. We can understand it more clearly in actual use.你不中，他更得不到你。鲜亮清新的画面、时尚靓丽的演员、曲折动人的爱情故事，加上宁波旖旎迷人的风光，当然故事情节也一波三折，该剧讲述了导游培训中心学员程小鹿（李小璐饰）专喜欢恶作剧，这让老师们非常头疼，培训中心新来了一位老师丁健（常铖饰），他潇洒英俊，还透着几分神秘。小娃儿言辞恳切，显见得把爹娘教导都记在了心上，不过用错了地方而已。
