Located in the eastern province of Chu, work at the tomb began in 2019 because reports had found it was a common target for looters and excavations have shown it to be the most complex funerary structure from its time ever discovered in China.

Over 3,000 relics, including lacquered wood products, bronze vessels, figurines, chariot and horse pits, and sacrificial remains all found in addition to a woven bamboo mat that allowed scientists to get a radiocarbon analysis that showed the tomb's age.
