NANJING, CHINA—A tomb discovered last year in east Jiangsu Province may have belonged to the notorious Yang Guang, the last emperor of the Sui Dynasty (A.D. 581–618). His name was found on a stone in the tomb, along with an inscription of the year he was killed in a mutiny. “But we’re still not sure whether it was the emperor’s final resting place, as historical records said his tomb had been relocated several times,” said Shu Jiaping of the City of Yangzhou’s Institute of Archaeology. The tomb also contained a belt made of jade and gold, and it was connected to another tomb that may belong to the empress.
