I come from Zheng Da University, and my experience tells me that location is the most important thing. Among these schools, the southwest location is the best in Chongqing. Generally speaking, the school is better than Zheng Da University, depending on the major you apply for. The most outstanding school of Zheng Da University is Medical College, which has six affiliated hospitals. Chemical engineering and communication are both good majors. You choose a place first, then a school, and then a major. It's not that the major is not important, but you may not be able to attend the ideal major of your ideal school. So, you choose the school first. Southwest is the combination of former Sichuan Normal University and southwest agriculture relative agriculture. As for the geographical reasons of the other two schools, it is not recommended. Personally, don't spray. My opinion: the most important thing is geographical location. Go to the city you want to go to. Trust me, this is the most important thing. Don't think that you can take the postgraduate entrance examination in the future.
