—— 果戈里 （俄）Гоголь (Russia)

Time is the yardstick of all things and the basic law of architecture. As the carrier of human activities, architecture is also a life like dynamic system. Architecture has the ability to deal with the changing factors that affect the existence and development of architecture, to seek advantages and avoid disadvantages, so as to achieve the purpose of adjusting, adapting and improving human living space and environment.

建筑的功能随使用主体和时间的变化而变化；建筑的空间在时间视角中是多义的;建筑形态因时间的流逝而以不同形式展现出来；对建筑意义的解读因时而异，因人而异。建筑的功能，空间，形态和意义共同构成建筑时间性的范畴和价值。

The function of architecture changes with the change of using subject and time; the space of architecture is polysemy in the perspective of time; the architectural form is displayed in different forms due to the passage of time; the interpretation of architectural meaning varies with time and people. The function, space, form and meaning of architecture constitute the category and value of architectural temporality.

The No.125 factory of China’s military industry, namely AVIC Beijing Shuguang electric machinery factory, is always called  “Shuguang factory”. Under the guidance of the general line of “encouraging enthusiasm, striving for the upper reaches and building socialism more quickly, better and more economically”, Shuguang factory was completed in 1959. It is under the jurisdiction of AVIC. It is responsible for the R & D and production of aviation motors (such as the main motors of J-7 III and J-8 II fighters). It was once a military security unit and a solemn and sacred place. Shuguang factory is located at No.5, Jingshun Road, Sanyuanqiao, Dongzhimen, Chaoyang District, Beijing. The main building consists of seven single storey workshops in one line and six horizontal directions, as well as a three storey dormitory building in the East. The building structure is clear and well preserved.

As a historical building that played an important role in the military industry in the early days of the people’s Republic of China, Shuguang factory is a relic of the times. In 2019, Shuguang factory has completed its 60th anniversary. As a kind of dynamic system of life, Shuguang factory should not exist only as an industrial building or a historical relic in the process of time flow, and any building should not be simply and rudely defined. The ability of building itself to deal with external influence makes its use function, internal space, external form and architectural meaning change with the change of user and social environment. Therefore, the definition of architecture must take the specific time node as the primary premise.
