For centuries, China's Great Wall served as protection for millions across the country. Since ancient times, it has become one of the world's many wonders. But natural and man-made degradation have taken their toll on the wall, and experts say now is the time for everyone to help preserve this world-renowned landmark. CGTN's David Deen explores the options.

Protection of China's Great Wall has always proven to be a difficult task. Its wide distribution, complex preservation environment and location across underdeveloped areas present numerous challenges. To solve the problem, authorities are encouraging public participation in protecting it. The Great Wall Conservation Union was established in June, 2018. It aims to promote the spread of Great Wall Culture and improve the quality of Great Wall Tourism.

LIU YUZHU, ADMINISTRATOR NATIONAL CULTURAL HERITAGE ADMINISTRATION "The conservation union will try to explore related concepts, experiences and technology exchanges in the Great Wall's unified interpretation, publicity, and management. Professional institutions and enterprises are encouraged to take part in the conservation of the wall as well."

Liu encourages better on-site presentation and interpretation of important sections of the wall. Meanwhile, experts say modern technology should be fully used to publicize and present the culture and spirit of the Great Wall.

SONG XINCHAO, DEPUTY ADMINISTRATOR NATIONAL CULTURAL HERITAGE ADMINISTRATION "Over the years we have been exploring the introduction of high-tech means, such as the use of drones; also satellite images to compare and analyze the areas where the points of the Great Wall are located, including the construction along the Great Wall."

It's the longest man-made structure in the world, and snakes through the vast expanse of northern China. It cannot be simply collected and protected in a museum. Experts say preservation efforts cannot come from just cultural relic enthusiasts adding that society must do its part in protecting the Great Wall of China. David Deen, CGTN.
