Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia翘儿也在旁鼓励：好好想想相公，不难的。/groan (groans)　　为了追星，于佑彤引发出一连串的乌龙事件，也殃及梦想成为大明星的武打替身孙帆（陈楚河饰演），因误会方子浩企图染指他浮沉在娱乐圈边缘的小模女友星野真（田中千绘饰演），而将方子浩痛打了一顿。Hello!残灯末日大清国，黄瓦红墙紫禁城，两对恋人的爱情，在这里燃烧，在这里熄灭。少女吟儿出嫁前夕，被强召入宫，选为宫女。她和未婚夫荣庆未进洞房，已成破镜两人信守“不求同日生，但求同日死”的诺言，苦苦思念，盼望着聚首的一天。吟儿九死一生，先后伺候过西太后、珍妃和光绪。荣庆辗转京城内外，艰辛备尝。他们经历了清末一系列重大历史事件，这一对名不见经传的小人物被惊心动魄的宫廷恩怨时而抛上浪尖，时而打入谷底。光绪皇帝和珍妃的爱情被埋葬了。十年寒暑，不幸大幸，吟儿和荣庆却由于西太后的“格外恩典”破镜重圆，终拜花堂。谁知天道不古，命运弄人，洞房之夜却双双殒命，终于“生不同床死同穴”。同一时刻，西太后和光绪也走完了他们的生活旅程，丧钟响起，深宫日落。紫禁城内外，四位主人公同赴黄泉……大人物，小人物，交织绘成一幅清末悲剧长卷。
