I am a student majoring in automation in Zibo Spark College in 2008. At that time, the economic crisis made the department inefficient. After on-the-spot investigation and comparison, we finally chose Spark. I feel that the teachers there are excellent in all aspects. After two months' study, I deeply feel that Mr. X (I won't mention who he is here in case some friends doubt him) is a very serious and responsible teacher, with profound knowledge and almost one-on-one teaching for students. Although I have started my own company now! !
