First of all, selling degrees violates the provisions of the education law, because the education law stipulates that educational institutions must enroll students in accordance with the enrollment procedures and admission standards stipulated by the state, and may not arbitrarily lower the admission standards or illegally enroll students in other ways.

Secondly, selling degrees may violate other relevant laws and regulations, such as the Advertising Law of People's Republic of China (PRC) (PRC).

For the act of selling degrees, the relevant legal responsibilities are as follows:

1. Whoever, in violation of the provisions of the Education Law, lowers the admission standards without authorization or illegally enrolls students by other means, if the circumstances are serious, shall be punished by the education administrative department or other relevant administrative departments according to law.

2. Whoever, in violation of the provisions of the Advertising Law, publishes false enrollment advertisements or false information to deceive or mislead the public, shall be ordered by the administrative department for industry and commerce to stop the illegal act according to law, and shall be given administrative penalties such as fines.

Therefore, it is illegal to sell a degree, and the relevant responsible person needs to bear the corresponding legal responsibility. At the same time, the education administrative department and other relevant administrative departments should strengthen the supervision of enrollment work to ensure that enrollment work is fair, open and transparent.
