<p>老子骑青牛过函谷关</p>
</div>
<h3>简介</h3>
<p id="brief">李聃，名耳，字伯阳、外字聃，世人尊称为“老子”，华夏族，生于中夏东周末的某诸侯国苦县厉乡曲仁里（今河南省鹿邑县），师从殷商末臣之商容，于东周春秋末之周守藏室任吏、春秋时代思想家，隐居邢台广阳山。此人有著作被人们广泛奉为<a href="https://www.daodejing.org">《道德经》</a>，是道家的经典、全球文字出版发行量最大的著作之一。
李聃的学说后被庄周、杨朱等人发展[2]，后人奉为道家学派之开教宗师。《史记·老子韩非列传》中曾记载孔子向老子请教关于礼的问题。老子主张无为而治、天人合一、清静无为的统治理念，和庄子同样是道家的人物，或与太史儋并列，存世约有一百六十余岁或二百余岁。
  李聃被尊为道教始祖、东方三大圣人之首，唐朝追认李聃为李姓始祖。老子是世界文化名人，世界百位历史名人之一。</p>
