If you are not a minority, forget it. Preparatory courses are all for ethnic minorities or the preparatory courses of the General Armament Department. Sichuan Normal University has not recruited general preparatory courses for many years. Because there are independent colleges now, that is, three books, when there were no three books before, there were more preparatory courses. . . The General Armament Department's preparatory course is for the employees and their children in the major bases of the General Armament Department of the China People's Liberation Army. It seems that only Sichuan University has a preparatory course for final assembly in Sichuan.
