In the history of China, which year was it not allowed to repeat after the college entrance examination?

The education department responded to the question of repeating the college entrance examination, saying that it is forbidden for public high schools to recruit repeat students. However, at present, only Sichuan, Yunnan, Guizhou and Heilongjiang have successively issued bans, which have not involved the whole country. However, this is a signal released, indicating that the state should ensure that the college entrance examination is absolutely fair, and such unfairness is not allowed. Once found, it will be resolutely stopped. Ministry of Education: In 2022, college entrance examination immigrants will be completely restricted. Another way is "college entrance examination immigration". These parents send their children to prestigious schools and send them to cities with low scores to take the college entrance examination one year before the college entrance examination, which seriously affects the fairness of the college entrance examination. To some extent, college entrance examination immigration is also a kind of cheating. We should stop this behavior and maintain the fairness of the college entrance examination, which is also fair to every student. Therefore, the Ministry of Education has also issued a notice in this regard, "the college entrance examination does not immigrate", and it is expected to achieve provincial coverage in 2022.
