The music department of Jida and Cheng Yi are not the same department at all. The music department of Jida is in the Conservatory of Music, while the music department of Cheng Yi is just a department. So, to say these two are good, I suggest you choose the big one. Because, after all, Jida currently belongs to one book, and Cheng Yi only has three books (although there are no three books in Fujian now). I can't say what Jia Geng said. After all, it is difficult to evaluate Jia Geng of Xiamen University, but I dare say he is better than Cheng Yi.
