  Laozi served as a keeper of archival records at the court of Zhou. Confucius (551–479 B.C.E.) had consulted him on certain ritual matters, we are told, and praised him lavishly afterward (Shiji 63). This establishes the traditional claim that Laozi was a senior contemporary of Confucius. A meeting, or meetings, between Confucius and Laozi, identified as “Lao Dan,” is reported also in the Zhuangzi and other early Chinese sources.
