During this period of time, I happened to be traveling in Kunming. I specially found time to visit the "Yunnan Normal University" in the center of Kunming, which is the former site of the once brilliant and splendid "National Southwest Union University", to remember the excitement. The years of the heart. "National Southwest Union University" can be said to be China's oldest university. Why do you say this? Because the name of the university is called "United University", because it is a university jointly run by National Tsinghua University, National Peking University and private Nankai University, it can unite the three top universities in China. You said that cattle are not cattle? On November 1, 1937, the National Changsha Temporary University, established by the National Peking University, National Tsinghua University, and Private Nankai University in Changsha, opened in Changsha, but was bombed by Japanese planes in Changsha. In mid-February 1938, The Changsha Temporary University moved to Kunming in the west, and in April 1938, it was renamed the National Southwest Union University. In August 1946, after the demobilization of teachers and students from Tsinghua University, Peking University and Nankai Campus, the Southwestern Masters College remained in the former site of Kunming United University and was independently set up as the National Kunming Teachers College to 1984. It was renamed "Yunnan Normal University" at the time, and the former site of "National Southwest United University" has now become a national key cultural relics protection unit and is free to the public.
