Changxin Palace Lantern in the Western Han Dynasty, a bronze ware of the Han Dynasty in China, was unearthed in the tomb of Dou [w m 4 n] [w m 4 n], the wife of Zhongshan King, in Mancheng County, Hebei Province (now about 1.5 km southwest of Mancheng County, Baoding City, Hebei Province) in 1968. 20 10 was exhibited as an exhibit of China 20 10 Shanghai World Expo. The lamp body of the palace lantern is a gilded maid-in-waiting, sitting with the lamp in both hands, with an elegant expression. The lamp body is 48 cm high and weighs 15.85 kg. The design of Changxin Palace Lantern is very clever. The maid-in-waiting seems to be sheltering from the wind with a lamp in one hand and a sleeve in the other. It is actually a rainbow tube, which absorbs oil smoke, which not only prevents air pollution, but also has aesthetic value. This palace lantern was named after it was once placed in Changxin Palace in Dou Taihou (Liu Sheng's grandmother), and now it is in the Hebei Provincial Museum.
