Away from the hustle and bustle of the city, avoid the impetuous crowd. Into the quiet valley, open the antique wooden door. Experience the close combination of man and nature, the collision of the beauty of mind and nature, and the generosity of the unity of body and mind between man and the mountains and forests. This is the "Dacheng Xiaoyuan" boutique B&B in Xiashizi Village, Dachengzi Town, Miyun District, Beijing, carefully cast by Beijing Urban Construction Group.
