The excavation found more than 10 sets of ancient bronze artifacts for ceremonial use, including pots, cups, daggers and arrows at the No.4 tomb, said Huang Fengchun, a researcher from Hubei Cultural Relic Research Institute.

"Inscriptions, fine jade decorations and floral patterns can be easily identified on the surface of these artifacts," Huang said.
