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.剧情描述一个犹太拉比的儿子一心想成为百老汇明星，唱歌跳舞。此举遭到家长的强烈反对。他们只想让他成为犹太教仪式中的领唱。但是深深热爱爵士乐的儿子一心只想唱流行歌曲……那先谢过杨大人了。讲述了一段90后富二代混进校园当老师，并与00后的鬼马学生们展开了一系列师生大PK的校园喜剧故事。这个故事发生在英国英格兰林肯郡lincolnshire。《佛本是道》这部小说，就是他内心深处一直想看，却一直没有看到的那部小说。只要有脑子的人都会知道，凭着笑傲江湖的名头，凭着天启的名气，这部电影就算想亏本都难。
