SHAANXI PROVINCE, CHINA—A tomb complex said to be the second largest in China was uncovered during the expansion of the Xi’an University of Finance and Economics. International Business Times reports that inscribed pottery and artifacts of jade, gold, and silver suggest that the tomb was built by the first emperor, Qin Shi Huang, for his grandmother, although a sarcophagus has not been found yet. The tomb also contained two carriages and the skeletons of 12 horses. Such carriages, pulled by six horses, were a symbol of royal rank.
