Three years, in the south campus, the environment is ok. This major belongs to the national class B, and it is OK, and the teaching staff is OK. Many of them are returnees, so they are relatively easy to get online. I was admitted this year, and I feel that I was only ready to start studying in September last year. Take a good look and it will be done in a few months. Good luck. Besides, I have a stereo, the whole set!
