Speaking of Northwestern Polytechnical University, we have to start from an era of war. During the period of 1937, the Lugouqiao Incident broke out, and Ping Jin fell one after another, and the universities gathered here also faced the critical moment of life and death. In order to avoid the war, a group of Pingjin University represented by Peking University and Tsinghua University chose to leave the occupied areas and move to the rear. As we know, National Southwest Associated University is the product of the crisis.
However, Peking University, Tsinghua and Nankai were not the only universities that chose to migrate at that time. The route of university migration is not just south. Some colleges and universities choose to go directly to the west, settle in xi 'an, Shaanxi, and set up Xi 'an Temporary University. They are National Peiping University, National Peiping Normal University, National Beiyang Institute of Technology and Beiping Research Institute. After Taiyuan fell into war, Xi 'an Temporary University moved to Hanzhong, Shaanxi Province, and at the same time absorbed a number of institutions that moved to the northwest, and changed its name to "National Northwest Associated University".
Northwest Associated University, like the National The National SouthWest Associated University, has brought rich college education resources to the northwest region. Among the three universities that make up Northwest Associated University, the National Beiping Normal University resumed its operation after the war, which is now Beijing Normal University. The National Beiyang Institute of Technology, founded by Sheng Xuanhuai, Minister of Westernization in the late Qing Dynasty, became Tianjin University after its resumption. National Peking University is a consortium of universities in Ping Jin, which was integrated by the government at that time.
