In UESTC Education & Application System, the Specialties/Majors of PhD are different from the CSC system (https://www.campuschina.org/). The specialties shown in the CSC system are more like the research field in UESTC specialty/major system.
While applying in the UESTC Application System, please select the corresponding specialty/major instead, try to find the close research field before you make application.
The Specialty/Major shown on the UESTC Admission Letter and Graduation Certificate will be the one in the UESTC system.
