A cemetery consisting of three tombs was recently listed as one of the five key archaeological discoveries in Henan Province in 2022. In the tombs probably built between the late period of the Northern Wei Dynasty (386-534) and the Eastern Wei Dynasty (534-550), large-scale and well-organized stone beds with stone folding screens were found. This is the first time that stone beds dating back to this period have been unearthed in Luoyang City. (Xinhua/Li An)
