•小望　往西邊去（中島朋子）I always can't get promoted, but I still like to be a policeman.所以他不像蒲俊那样，对闽越和东瓯有详细的了解和分析。唐僧距西天取经归来至今已有1500多年，唐僧在西天身居降龙罗汉一职，每天同诸位天庭官员打牌玩乐，多年的磨砺本已让他性格变得圆滑，可惜祸从口出，触怒了如来佛祖，被如来佛祖打回人世，再经历八十一难。唐僧来到人间后，发现自己名气虽大，却没人相信自己就是唐僧，时间长了，也开始为生计担忧，还在求生过程中陷入了无数困境。身边没有孙悟空的唐僧只能自己面对困难，不料闹出了种种洋相和哭笑不得的故事，现代价值观的差距，天界神仙们的使坏，唐僧是否能够经得住八十一难的考验，重回天界。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 EncyclopediaSubsequent results
