Avoid coupling the sender and receiver of the request, make it possible for multiple objects to receive the request, connect these objects into a chain, and pass the request along this chain until an object processes it. This is the responsibility chain mode. In the responsibility chain mode, it is possible for each object to process the request, thus realizing decoupling between the sender and receiver of the request. At the same time, the responsibility chain mode simplifies the structure of the object, which makes each object only need to refer to its successor without knowing the whole chain, thus improving the flexibility of the system and making it more convenient to add new request processing classes. However, we cannot guarantee that all requests can be processed in the responsibility chain, and it is not conducive to observing runtime characteristics.依仗个鬼，庞取义只有窃喜，昨儿试炮真是试对了，被表扬啦哈哈。原著小说中，张无忌是在悬崖之下找到《九阳神功》秘籍的，这次，山崖之下，并没有出现秘籍。3 雨夜的访问者16岁的Vivien被困在Vestalis学院，这是一所像监狱一样的寄宿学校，她对自己保持沉默，不为任何人伸出脖子。直到她和背叛她的前朋友索菲亚重聚。女孩们一起进行了一次危险的搜索，以发现监禁背后的可怕真相。很快，女孩们就要为自己的生命奔波，要么自救，要么就得努力死去。让小灰叼了送给那个正在院子里洗衣裳的媳妇。You're sixty!
