The Changxin Palace Lantern of the Western Han Dynasty was unearthed in 1968 from the tomb of Dou Wan, wife of Prince Jing of Zhongshan, Liu Sheng, in Mancheng County, Hebei Province. It was exhibited as an exhibit at the 2010 Shanghai World Expo in China. The body of the palace lantern is a gilded whole, and the palace maid sits with both hands holding the lantern, with a peaceful and elegant expression. The lamp body is 48 centimeters high and weighs 15.85 kilograms. The design of the Changxin Palace Lantern is very clever. The palace maid holds the lantern in one hand and the sleeve in the other hand seems to be blocking the wind, which is actually a rainbow tube used to absorb oil fumes. It not only prevents air pollution but also has aesthetic value. This palace lantern is named after its placement in the Changxin Palace of Empress Dowager Dou (grandmother of Liu Sheng) and is now housed in the Hebei Museum.
