The Fusuijing Building, also known as the “Socialist Building” was constructed in 1958. It is located in Gongmenkou in Xicheng District. It is an eight-storey building and was the earliest residential building with elevators in Beijing. After the Great Hall of the People was finished, the remaining materials were used its construction. The 25,000-square-meter "Z"-shaped building is so grand that it is difficult to get a complete picture from any angle when viewing it from the hutong community northwest of Baita Temple where it is situated. Its most prominent feature was the public cafeteria, which fully reflected the socialist characteristics of the times. Now, as a modern historical building in Beijing, the entire structure has been preserved.
