Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.大学毕业后，四位朋友一起分享他们的梦想。美版生人勿进是2010年马特·里夫斯执导的美国电影。影片中欧文是一个孤独的并且经常受人欺负的12岁小男孩，他的新邻居是一个神秘的年轻女孩艾比，他们做了朋友。恰逢周围发生了一系列令人毛骨悚然的事件，欧文了解到，他的新朋友是一个吸血鬼，但是他们之间友谊的力量却远远强大过恐惧。但原本平静的小镇接连发生了几起命案，这一切好像都与艾比有关，小镇迅速被死亡的阴影笼罩。原来是艾比的“父亲”在帮艾比找人血，他将人残忍的杀害榨干其血给艾比喝，但在一次事件中艾比的“父亲”意外毁容，在他生命的最后一刻他把自己的血献给了艾比练久了，根本不用踩板子，就能从沼泽地里轻飘飘地踏过去。本剧讲述了从上流家庭逃出来的奇怪少女徐春和优等生韩仁尚因未婚先孕，使得平凡人家的女孩嫁入豪门后引发出的的一系列矛盾与混乱的故事。爱德华·刘易斯是个身家百万的企业巨头，也是个潇洒迷人的青年男子。但是麻烦的是他总是搞不好和女人的关系，最近，他与女友的关系又破裂了。
