This article focuses on the architecture of China during the Great Leap Forward. The Soviet Union provided assistance in all areas, including architecture. Soviet architects designed large urban-planning ensembles in Chinese cities in the Stalinist Empire style and intensified the education and development in China of the New Folk Architecture direction, which was determined by the styles "Chinese Form" and "Style 1959". Three styles were officially recognized as national in the state. They defined a new image of socialist cities. Each style had characteristic features: means and types of composition, details and elements, colors. Despite the various methods of constructing buildings, these styles were genetically related, and they defined an entire era in national architecture. All ensembles in Harbin of this period were included in the architectural collection of the city, became architectural monuments and are protected by the state. Buildings in the Stalinist Empire style are a Soviet legacy abroad. They are now the prototypes for many new buildings.
