Introduction to the ancient city of Liqian: In 53 BC, the Roman consul Crassus gathered seven legions to invade Parthia (Iran) and was surrounded and annihilated in Kalai. Publius, the eldest son of Crassus, led the first legion to break out of the encirclement, crossed the eastern border of Parthia, and migrated to the Western Regions. After many years of travel, around 36 BC, they successively returned from the Dayue clan Xiongnu to the Western Han Dynasty, and were resettled in today's Yongchang County. Come to the village. The Han Dynasty called Rome Liqian, so Liqian County was established, and the Roman people were given the power to farm and herd for a living, turning war into jade and silk.
