The number

3,000 historic relics

will be moved to a new high-tech warehouse by the end of the year. The relics were unearthed in 1957 from the underground palace of Dingling, the mausoleum of Emperor Zhu Yigou (1573-1620) of the Ming Dynasty (1368-1644). The new underground warehouse - with 2,435-square-meters of floor area and advanced fire, security and air conditioning equipment - will provide constant humidity and temperature.
