Longshan Culture has derived its name from the remains of the Longshan Township of Shantung Province, China. Geologically, Longshan Culture covers mainly the lower part of the Yellow River, including the areas of Honan, Shensi and Shantung Provinces. Longshan Culture jade artifacts contain many varieties including jade kwei, jade arched pendant, jade tube, bi-disk and notched bi-disk most of which are carved elegantly and dexterously. Judging the motifs and the style of line carving, the Longshan Culture jades are believed to be the origin of Shang Dynasty jades. The eagle motif on one of the kwei is believed to be the origin of Shang Dynasty jade eagle.
