The Hongshan culture is an ancient Neolithic culture that existed in northeastern China, primarily in what is now the Inner Mongolia and Liaoning provinces, approximately 4700 to 2900 BCE. Archaeological evidence suggests that the Hongshan culture was one of the earliest known cultures to produce and use jade artifacts in China.

Jade artifacts from the Hongshan culture have been discovered in archaeological sites, including burial sites and settlements. These artifacts include jade ornaments, figurines, tools, and ritual objects. Jade held significant cultural and symbolic importance for the people of the Hongshan culture, and it was used in various aspects of daily life, religious practices, and burial rituals.

Some of the most notable jade artifacts from the Hongshan culture include intricately carved jade dragon figurines, bi disks, and cong tubes. These artifacts demonstrate advanced jade carving techniques and artistic craftsmanship, indicating the cultural significance of jade during this period.

The age of Hongshan culture jade artifacts can vary, but they are generally believed to date back to the Neolithic period, making them several thousand years old. These artifacts provide valuable insights into the early development of Chinese civilization and the cultural significance of jade in ancient China.
