The frightful punishments ‘invented’ by Vietnamese teachersVietNamNet Bridge - A third grader in Hai Phong was forced to drink water wrung from a board-cleaning cloth. These are a few of the punishments used by some teachers, who have criticized by parents and the public on social media. Nguyen Thi Minh Huong, an elementary school teacher in Hai Phong, ‘went too far’ when punishing a third grader. Huong, 25, became ‘famous’ for coercing the student to consume dirty water in class as a punishment for making noise in class. The punishment was also applied by the same teacher again and by other teachers, who thought it was ‘very effective’.
