Jieyang jade, especially high-end jade, is well-known in the industry. Jieyang is one of the largest mid-to-high-end jade design and processing bases and trading distribution centers in the country and even in Southeast Asia. It is also one of the largest producers of mid-to-high-end jade jewelry in the country. It is one of the largest suppliers of high-end jade lots from auction houses such as Sotheby's, Christie's, and Poly. In recent years, the traditional jade market has been sluggish. Jieyang government departments have actively adapted to the "Internet +" era, guided traditional jade companies to transform into e-commerce, broadened jewelry consumption channels, and vigorously developed the e-commerce industry. Jieyang Douyin e-commerce live broadcast base was officially launched at the opening ceremony of the 19th Jade Culture Festival to facilitate online jade transactions.
