Because Chongqing belonged to Sichuan before 1997, it was reasonable that Sichuan International Studies University was in Chongqing at that time and Sichuan was in its name.

Sichuan International Studies University 20 13 was named Sichuan International Studies University, 1953 was expanded from Southwest Russian Institute, and a military school was located in Chongqing.

It's a bit strange that Sichuan is outside Chongqing, but the names outside Sichuan have been typed out. If you change your name again, it will cost a lot, so the name has been kept.
