No, according to the official website of Central South University, from the educational principle, any form of fraudulent release of water is immoral and even illegal. Evaluating students' knowledge level and ability fairly and objectively in the examination is the cornerstone of maintaining fair competition and selecting talents. Fraud or water release is tolerated or implemented, then the whole evaluation system and selection mechanism will be destroyed, which is unfair to other candidates and the whole society. In any case, students should be responsible for their own actions, abide by school rules and examination rules, and get good grades through their own efforts and abilities. At the same time, schools and teachers should also strengthen the supervision and management of examinations and maintain a fair and equitable examination environment.
