A section of the Great Wall of China, located in Yanqing District, is shown under a clear, bright blue sky. The robust stone wall, featuring crenellated parapets, ascends steeply towards a prominent, multi-story stone watchtower. The watchtower has multiple arched openings and rectangular battlements. Numerous individuals, estimated between 50 and 70, are observed on the wall's pathway, which consists of wide stone steps. These individuals, appearing to be tourists, are distributed along the ascending path and clustered near the watchtower. They are dressed in varied casual outerwear, including jackets and hats. The surrounding mountainous slopes are covered with dense, predominantly leafless or sparsely foliated deciduous trees and shrubs.
