　　In recent years, Beijing has formed a new pattern of Beijing Great Wall protection with heritage protection as the core, the protection and development of the Great Wall Cultural Belt as the theme, and the construction of the Great Wall National Cultural Park as the focus, and has accumulated new experience in the protection, inheritance and promotion of the Great Wall culture.

　　In order to explore new methods and paths for the protection of the Great Wall itself and the value of the Great Wall, since 2018, Beijing has launched a pilot project to introduce archaeological excavations into the protection and repair of the Great Wall.

　　"Before encountering the collapsed brick walls of the Great Wall, the construction workers may remove them. Now, because of the introduction of archaeological excavations, experts from various fields can read information from history and provide a basis for a series of subsequent protections." Chen Mingjie, director of the Cultural Relics Bureau, introduced at the 2022 Beijing Great Wall Cultural Festival, which opened on the evening of the 20th, to prevent the disregard and destruction of the historical information of the cultural relics, and to provide an important design reference and protection basis for the subsequent rescue and reinforcement of the Great Wall.
