The vast majority of the museum's staff have no idea what their workplace looks like after dark. However, for this special event, the employees will be allowed to attend this week's night visits.

The exception to the curfew, in 2015, happened when one of China's best known ancient works of art, the Northern Song masterpiece Along the River During the Qingming Festival was displayed during an exhibition in the Hall of Martial Valor. The overwhelming number of visitors caused the museum to allow late entry to the hall, even extending past midnight.
