According to the information displayed by Gao Dun Education Network, the specific reasons are as follows:

1. Sino-foreign cooperation in running schools is a form of joint training of universities at home and abroad. Colleges and universities have regulations on such courses, and it is not allowed to change majors after admission.

2. Chinese-foreign cooperative education majors only recruit science students. Once you are admitted, you are not allowed to change your major. Candidates who do not fill in the voluntary cooperation in running schools will not be transferred to this major. Therefore, Chinese-foreign cooperation in running schools cannot be transferred to ordinary majors.
