"Judging from the costumes of the inscribed figures, we decide these inscriptions were made in the second half of the eighth century or the first half of the ninth," said Zhang Yanqing, an associate professor at the institute.

Archaeologists said the inscriptions reflect the communication between eastern and western culture during the Tubo period. They are also evidence of cultural communication and religious transmission between Tibetans and neighboring ethnic groups in ancient times.
