到了宋代,人们便开始在桃木板上写对联,一则不失桃木镇邪的意义,二则表达自己美好心愿,三则装饰门户,以求美观。又在象征喜气吉祥的红纸上写对联,新春之际贴在门窗两边,用以表达人们祈求来年福运的美好心愿。为了祈求一家的福寿康宁,一些地方的人们还保留着贴门神的习惯。据说,大门上贴上两位门神,一切妖魔鬼怪都会望而生畏。在民间,门神是正气和武力的象征,古人认为,相貌出奇的人往往具有神奇的禀性和不凡的本领。他们心地正直善良,捉鬼擒魔是他们的天性和责任,人们所仰慕的捉鬼天师钟馗,即是此种奇形怪相。所以民间的门神永远都怒目圆睁,相貌狰狞,手里拿着各种传统的武器,随时准备同敢于上门来的鬼魅战斗。由于我国民居的大门,通常都是两扇对开,所以门神总是成双成对。唐朝以后,除了以往的神荼、郁垒二将以外,人们又把秦叔宝和尉迟恭两位唐代武将当作门神。相传,唐太宗生病,听见门外鬼魅呼号,彻夜不得安宁。于是他让这两位将军手持武器立于门旁镇守,第二天夜里就再也没有鬼魅搔扰了。
