How do you feel about our school being located in the mountains? How do you feel about our school itself? How do you feel about interacting with our Chinese students in the classroom? How do you feel about watching the programs performed by our students & teachers? But in the last one, I am not sure what you mean by "programs", so I would recommend finding a different word for it. But I can not suggest a different word until you explain what you are referring to here.

Well done. You just need to add THE to mountain area in Q1. Or you could even say ‘in the mountains’

Here are the revised interview questions: 1. How do you feel after visiting the school in the mountainous area? 2. How do you feel after visiting our school? 3. How do you feel when you enter the class and interact with the Chinese students? 4. What are your thoughts on the performances by the students and teachers? Feel free to ask for any further adjustments!
