Li's necklace consists of 28 golden spherical chain beads, each of which is welded by 12 small gold rings, and each of which is inlaid with 10 pearls, which is sparkling and dazzling. The center of the upper end of the necklace is round, with a dark blue pendant engraved with a deer.

Li, a native of Longxi, Gansu Province, is the great-granddaughter of the Northern Zhou General and the daughter of Dr. Guanglu. She was spoiled by her grandmother Yang Lihua, the Empress Dowager of the Northern Zhou Dynasty, and was raised in the palace since childhood. Emperor Yang Di died in the palace for four years when he was nine years old. Yang Lihua was heartbroken and buried with a generous gift. 1957 Li's tomb was discovered in the west of Ancheng, with the most complete preservation and the highest grade and specification. The necklace was unearthed there.
