Introduction to Tiangong Han Jade: The "Tiangong Han Jade - Xuzhou Han Dynasty Jade Boutique Exhibition" exhibition hall is the only permanent exhibition of unearthed Han jade in my country. It is located in the north exhibition hall on the second floor of the exhibition building and has about 180 pieces (sets) of exhibits. The Han Dynasty jades unearthed in Xuzhou represent the highest level of jade production in the Han Dynasty in my country. These precious ancient jades are warm and graceful, with exquisite patterns and exquisite craftsmanship, vividly displaying the essence of traditional Chinese jade culture.
