BEIJING, Dec. 22 (Xinhua) -- An exhibition about the history and culture of the Temple of Heaven has opened to mark the 600th anniversary of the royal altar in Beijing.
The exhibition, located in the west wing of the Hall of Prayer for Good Harvest, or the main building called Qiniandian, presented a display showing the maintenance, renovation, changes, protection and inheritance of the UNESCO world heritage site in southern Beijing.
