Recently, netizen "Tony's Diary" published a short video revealing how some unscrupulous teachers treat students as "hostages" with differential treatment. Parents, fearing their children will be targeted, dare not complain, and must also shoulder extra tutoring tasks while teachers rely on putting pressure on students to achieve results and secure promotions. The video sparked widespread discussion among netizens, with a parent in Heilongjiang stating they had given a teacher a 1,000 yuan cash envelope, and a Guangdong parent saying their child was targeted but they dared not speak up.
