I don't know if you have noticed that the school emblems of Shanghai Jiaotong University and Xi 'an Jiaotong University are exactly the same except for their different colors. They both say "Jiaotong University", while the school emblem of Beijing Jiaotong University says "Beijing Jiaotong University". This is because Shanghai Jiaotong University and Xi 'an Jiaotong University used to be the same school, called "Jiaotong University" or "Jiaotong University", which was the earliest and most authentic Jiaotong University, and its predecessor was Nanyang Public School founded in 1896. As for other schools, whether Beijing Jiaotong University, Southwest Jiaotong University or other schools with the name of "Jiaotong University", their predecessors were not Nanyang Public School, but a school in Changchun. Although it is crowned as "traffic", it is not the same as the real Jiaotong University.
