At the Jiangnan Copper House, a copper sculpture museum established by sculptor Zhu Bingren and his son Zhu Junmin, the delegation participated in a hands-on session to learn copper relief art techniques.

"Copper sculpture is not just a craft, it is a cultural vessel. Through innovative designs, we aim to integrate this traditional art into modern life and showcase Chinese artisans' wisdom to the world," Zhu Junmin says.
