Qian Yu (1247-1320), styled Kuanfu, a native of Wuxi, Jiangsu, was a descendant of Qian Liu, King of Wuyue during the Five Dynasties and Ten Kingdoms period, and one of the prominent wealthy families in Wuxi during the late Song and early Yuan dynasties. He was buried in the first year of Zhizhi (1321). His tomb was discovered in 1958 during the construction of the Xingfu Reservoir by the Nanquan and Xuelang Communes in Wuxi City at the foot of Junzhang Mountain.

A large number of cultural relics were unearthed from the tomb, including goldware, silverware, jade ware, crystal, agate, amber, silk garments, lacquerware, paper currency, woodenware, and bronze mirrors, totaling 154 pieces, along with an epitaph. These artifacts possess significant historical, scientific, and artistic value.

Across the country, Yuan dynasty tombs with such rich burial objects and a very clear date are extremely rare. The Qian Yu Tomb in Wuxi and the Cao Shi Tomb (mother of Zhang Shicheng) in Suzhou are regarded as the "two gems" of Yuan tombs in the Jiangnan region. The unearthed cultural relics provide first-hand physical materials for studying the arts and crafts, daily life customs, family culture, and social economy of the Yuan Dynasty.
