Crown Prince Yi De, called Li Chongrun, was the first son of Li Xian, the fourth emperor of the Tang Dynasty. He was killed in Luoyang in 710 AD for his anger with Wu Zetian's dictatorship at the age of 19. In 705, he was awarded posthumously the title of Crown Prince Yi De. In 706, his body was moved from Luoyang to Qianling Mausoleum areas and was buried in a satellite tomb.

The Tomb of Crown Prince Yi De lies to the southeast of Qianling Mausoleum. There was a mound and enclosure walls. To the south of the walls were a pair of stone lions, two pairs of stone figures, and a pair of obelisks. The tomb consists of a tomb passage, three doorways, seven skylights, eight niches, front and back tunnels as well as front and back tomb chambers. The tomb passage is 100.8 meters long. More than 1,000 pieces of historic artifacts have artifacts have been unearthed from the tomb, including pottery figures, tri-colored glazed pottery figures, earthen wares as well as gold, bronze and iron wares.

The tomb is large in scale and abundant with burial articles. There are 40 well-preserved mural paintings on the walls of the tomb passage, doorways, skylights, front and back tunnels as well as front and back chambers. On the paintings are guards of honor, the Blue Dragon and the White Tiger( the god of direction), city walls, watch towers, musicians, men-servants and maids of honor, which show Li Chongrun's special identity and extraordinary statue. Take the mural Guards of Honor for example. In the Tomb of Princess Yong Tai, 12 halberds were painted just as in an imperial mausoleum. The mural painting depicts 196 guards of honor in three parts: infantrymen, cavalrymen and chariots. They look strong and powerful. There are also mural paintings entitled Out for Hunting, Maids of Honor, Display of Halberds and so forth. Rich in color and different in carriage, the Maids in Honor truly represents the daily court life in the Tang Dynasty. These mural paintings in the Tomb of Crown Prince Yi De are reflection of high artistic attainments and a feast for the eye. The excavation of the tomb has brought about an important discovery of the Tang Dynasty mural paintings in Shaanxi. The carved sketches on both sides of the stone outer coffin are fine and smooth, and they give a good expression to the features of the Tang-style carved sketches: smooth, clear and powerful.
