《孔雀东南飞》是我国文学史上录存的古代第一首长篇叙事诗,也是我国古乐府民歌代表作之一。它通过焦仲卿和刘兰芝的爱情悲剧,对封建制度和封建礼教的罪恶作了深刻的揭露和鞭挞,对诗中主人公的不幸遭遇和反抗精神寄予同情并加以赞扬,同时表达了人民对美好生活的向往。在教学过程中,学生常常会提出这样一个问题:既然刘兰芝如此勤劳善良,忠于爱情,为何焦母对她怀恨在心,以致于非赶走她不可?有人认为:刘兰芝没有为焦家传宗接代,因而被遣。然而,在我看来“无后”确实是刘兰芝被遣的一个重要因素,但不是根本的原因。我们知道,自汉武帝始,即推行“独尊儒术”的思想文化政策,至东汉章帝建初四年(公元79年)召开了著名的“白虎观”会议以后,封建的政权、族权、神权、夫权,成为牢牢束缚人民的四大绳索。在这样的封建伦理关系中,生活在汉末建安年间(公元196—219年)的刘兰芝,本来就是最深的爱害者;偏偏孔子曾骂别人“始作俑者,其无后乎”(《孟子·梁惠王上》),孟子又说道“不孝有三,无后为大” “Peacock southeast flight” is recorded in the history of Chinese literature, the first chief long narrative poetry, is also one of the representative folk songs of ancient Yuefu.

In the process of teaching, students often ask such a question: Since Liu Lansi so industrious and kind, loyal to the love, why anxious mother grudging her, so that she can not get rid of it? Some people think: Liu Lanzhi did not pass on behalf of Jiao Jia, So be sent. However, it seems to me that “nothing” is indeed an important element of Liu Lanzhi’s removal, but it is not a fundamental one. We know that since the beginning of the Han Dynasty, the ideological and cultural policy of “monopoly of Confucianism” has been implemented. After the famous “White Tiger concept” was convened in the first four years (AD 79) of the Eastern Han Dynasty, the feudal regime , Ethnic rights, theocracy, and the husband’s rights, have become the four major ropes that firmly bind the people. In such feudal ethical relations, Liu Lanshi, who lived in the Jian’an period (AD 196-219 AD) at the end of Han Dynasty, was originally the deepest victim of love; but Confucius once criticized others as “ Mencius Liang Hui Wang ”), Mencius said “ there are three unfilial, no great ”
