China Post will issue a set of four stamps and a miniature sheet on July 11 to mark the Forbidden City's completion's 600th anniversary and the 95th anniversary of its opening as the Palace Museum.

First officially occupied by the imperial court in 1420, the Forbidden City served as the royal palace of the Ming (1368-1644) and Qing (1644-1911) dynasties, experiencing many critical moments in Chinese history.
