Tao Te Ching
Mawangdui and Guodian texts

In 1973, archaeologists discovered copies of early Chinese books, known as the Mawangdui Silk Texts, in a tomb dated to 168 BC. They included two nearly complete copies of the text, referred to as Text A (甲) and Text B (乙), both of which reverse the traditional ordering and put the Te Ching section before the Tao Ching, which is why the Henricks translation of them is named "Te-Tao Ching". Based on calligraphic styles and imperial naming taboo avoidances, scholars believe that Text A can be dated to about the first decade and Text B to about the third decade of the 2nd century BC.

In 1993, the oldest known version of the text, written on bamboo slips, was found in a tomb near the town of Guodian (郭店) in Jingmen, Hubei, and dated prior to 300 BC. The Guodian Chu Slips comprise around 800 slips of bamboo with a total of over 13,000 characters, about 2,000 of which correspond with the Tao Te Ching.

Both the Mawangdui and Guodian versions are generally consistent with the received texts, excepting differences in chapter sequence and graphic variants. Several recent Tao Te Ching translations utilise these two versions, sometimes with the verses reordered to synthesize the new finds.
