“发昏章第十一”是“发昏”的戏谑说法。这种说法是怎样形成的,有多种解释,都难成立。本文认为“发昏”是借助“昏障”一词作为桥梁关联到“章第十一”的,“十一”就是“十”的强调形式。“不管三七二十一”的由来更是一个难解之谜。本文指出,“三七”是佛、道念诵经咒及传统医学治疗中常见的数量要求,以“七”为一周期,满足了“三七”之数,就能达到希望的效果,否则效果不好或无效,因此,当人们想表达不顾章法、不计后果的观念时,自然想到了“三七二十一”之数,于是就有了“不管三七二十一”的俗语。 “Twilight Chapter Eleventh” is “fainted ” banter. This is how the formation of a variety of explanations, are difficult to set up. This paper argues that “drowsy ” is the emphasized form of “” “ten ” by means of the word “drowsiness ” as a bridge linking to the eleventh chapter . “No matter thirty-seven twenty-one ” The origin is even more a mystery. This paper points out that “Sanchi ” is a common quantity requirement in the treatment of Buddhism, Taoist recitation and traditional medical treatment. With “seven” as a period, it satisfies the “three seven” To achieve the desired effect, otherwise the effect is not good or invalid, so when people want to express their disregard of the law, reckless ideas, naturally think of the “seven seven twenty-one” of the number, so there is Seven twenty-one "saying.
