He who has never been to the Great Wall is not a true man. The Wall which does not keep up with the times is not the Great Wall. Follow Yu Bo, Secretary of the Communist Party of China Yanqing District Committee to tour this picturesque tourist attraction and bring home "The Great Wall in Four Seasons." After this great journey, you'll be awed by a sea of lights of flowers in the Beijing Garden Expo Park, the ancient city reservoir at the Longqing Gorge, among other great wonders offered by wonderful Yanqing, an area harboring scenic attractions across the district during all seasons.
