An aerial drone photo taken on April 30, 2024 shows a worker doing archaelogical work on a watch tower of the Jiankou section of the Great Wall in Beijing, capital of China. Forty years ago, a campaign to protect the Great Wall with the help of social funds was launched in Beijing. Today, social forces still play a crucial role in the Great Wall protection and restoration. An ongoing restoration project of the Jiankou section of the Great Wall adopts a "simultaneous archaeology and restoration" approach, where archaeological work is completed on a section before restoration begins. The restoration project, with the participation of research institutions, universities and social organizations engaged in non-profit activities, is scheduled to be completed in 2026.
