Chinese archeologists have restored a 1,400-year-old royal crown, which belonged to the wife of Yang Guang, or Emperor Yang of Sui, the second and last monarch of the short-lived Sui Dynasty (581-618). The crown was unearthed in the tomb of the queen, known as Empress Xiao, in 2012 in Yangzhou. It is the oldest official crown of a queen ever found in China. The exhibition on the ancient crown kicked off in Yangzhou Museum Sunday. [Photo/Xinhua]
