A public transport card in the shape of imperial jade seal is seen in Xi’an City, Shaanxi Province. A joint creation by Chang'An Card, the provider of the Xi’an public transport card, and the Shaanxi History Museum, the card can be used for public transportation on buses and subways in more than 200 cities. The design was inspired by the jade seal of an empress in the Western Han Dynasty (206BC - 24AD) unearthed in 1968 just 1 kilometer from Changling, the mausoleum of Emperor Gaozu, Liu Bang, and his wife Lyu Zhi. One of the most important seals ever found, it is made of Hotan jade from Xinjiang Uygur Autonomous Region and is inscribed with the four characters "Huang Hou Zhi Xi" that mean it is an empress's seal. Tens of thousands of the jade seal cards were sold out.(Photo/IC)
