BEIJING, April 17 (Xinhua) -- China's National Cultural Heritage Administration has vowed to strengthen the protection of the Great Wall, which is more than 21,000 km long.
The protection and restoration work should ensure that the Great Wall relics remain where they originally existed and maintain their original look, said Song Xinchao, deputy head of the administration, at a press event on the Great Wall protection and restoration Tuesday.
Noting the importance of both routine maintenance and urgent repair of endangered sites on the Great Wall, Song said his administration would urge local authorities to check and find sites in need of repair and improve protection work.
"Some key sites suitable for visits can be opened to the public on a moderate scale," Song said.
The Great Wall, a UNESCO World Heritage Site, consists of many interconnected walls, some dating back 2,000 years.
There are currently more than 43,000 sites on the Great Wall, including wall sections, trench sections and fortresses, scattered in 15 provinces, municipalities and autonomous regions, including Beijing, Hebei and Gansu.
