I want to go to Yunnan University for Nationalities in Kunming and Chengdu.

Hello, take the train from Chengdu to Kunming Station and get off at Kunming Station. It takes about 18 hours from Chengdu to Kunming. After you get off, take bus No.2, just opposite the railway station exit, then turn to Jianshe Road and take 10, 84.65, etc. Do two stops and you will arrive at Lianhuachi Station. Across the street is the University for Nationalities. I hope it helps you! (To Chenggong University Town, take bus 184.98 to Juhua Village next to the railway station, and then take bus 170 to Minzu University. Do it. )
