After several failed experiences with restoration, they have opted for an ancient method to preserve this Wonder of the World. The work began in January 2019 due to the pressure of public opinion, and also because other previous restoration works ended up disfiguring some parts of the monument, causing a stir in social networks.
The engineer Cheng Yongmao, who runs the operations in Jiankou for 15 years, praises the new method of restoration. According to him it allows it to give “the impression to the people that the wall is original, as if it had not been repaired”.
