It is not 2 1 1, and the gap is not very big. It is difficult to make a mechanical distinction. If you want to study, I suggest going to Xihua. Xihua is the provincial focus of Sichuan, and there are not many schools with strong mechanical direction in Sichuan, so it will be easier to find a job in the future. After xi Jiaotong University, Xigong University, Chang 'an University and xidian university, Xi 'an Technology has to compete with Xi 'an Technology, Shaanxi Science and Technology, Xi 'an Engineering, Xi 'an Industry, Xi 'an Petroleum and Xi 'an Posts and Telecommunications, which is quite difficult. I hope I can help you.
