In his keynote speech at the event, Li Qun, director of the National Cultural Heritage Administration, called for in-depth study and implementation of Xi's guidance on cultural heritage work.

"We will deepen our research in key programs, including projects engaged in tracing the origins of Chinese civilization, systematically reveal the discoveries of ancient Chinese society and its historical development patterns," Li said.

Hongshan Culture was a key Neolithic culture renowned for its exquisite jade. It covered parts of today's Inner Mongolia autonomous region, as well as Liaoning and Hebei provinces.

In the early 1980s, a team of archaeologists discovered the Niuheliang site dating back 5,000 to 5,500 years in Chaoyang, marking a milestone in the study of Hongshan Culture.
