[2] A tomb about 4 kilometers (2.5 mi) southwest of Dingzhou from 55 BCE was discovered and excavated in 1973.

It contained several fragments of Han literature, including manuscripts of Confucius's Analects, the Taoist Wenzi, and the Six Secret Teachings, a military treatise.

The identity of the tomb's occupant is unknown, but Chinese archaeologists have speculated that it belonged to Liu Xiu or Xu Xing.

Under the early Republic, it was known as Dingxian (then romanized "Tingsien" or "Ting Hsien") from its status as the seat of Ding County.
