I am a student of South China University of Technology, but I am from Zhongshan, and I know these two schools better. If your grades are ok, I suggest you go to Zhongshan College of University of Electronic Science and Technology of China, which is better. This university has a good style of study and spirit. Moreover, Sun Yat-sen College is in the center and Hua Ruan is in the suburbs. Don't be misled by the upstairs. Teachers in Zhongshan are also better. In China, iSoftStone has a monthly traffic limit of 5G (previously 3G). It is difficult to find a job and a part-time job in China.
If that school is easy to get into, I'd say it's soft. There is an advantage in computer science here. In terms of major choice, I suggest you transfer to the Department of Digital Media when you come back to register. That major is 2000 yuan more than other majors, but you have learned a lot more.
