Harbin Institute of Technology moved to Beibei, Chongqing, and seized the campus of Southwest Normal University (at that time, Harbin Institute of Technology's national defense strategic position was very important, and everything else gave in), which is now the campus of Southwest Normal University. The campus of Southwest Normal University was once the seat of the East Sichuan Administrative Office in the early days of liberation, and there was also a Sichuan International Studies University. In order to support the relocation of Harbin Institute of Technology, the two universities unconditionally gave up their teaching office buildings and dormitories. Among them, Southwest Normal University moved to Liangping to run a school, occupying the middle school teaching building. It is said that middle schools have to occupy the teaching buildings of primary schools. There is no real winner in this magpie nesting series, and it is difficult to preserve the original site of Harbin Institute of Technology. Harbin Institute of Technology was placed under the jurisdiction of Heilongjiang Province, and merged with Heilongjiang Institute of Technology and Harbin Institute of Electrical Technology to form a new Harbin Institute of Technology. Moreover, the buildings and houses of off-campus units gradually encroached, which left a lot of trouble for Harbin Institute of Technology to clean up and rectify the campus environment after many years.
