A female teacher at an English center in Hanoi has been captured repeatedly yelling at a student and calling him “pig brain” after he refused to pay a fine for his violation in class.

The video clip was uploaded to social media on Saturday and has attracted over one million views along with countless comments and shares.

An initial probe by Tuoi Tre (Youth) newspaper showed that the incident took place inside a classroom of the MST English Center in the Vietnamese capital.

Both the teacher and representative of the English center have refused to give their comments on the incident.

In the nearly two and a half minute footage, the teacher demanded one of the students in her class pay a fine worth VND100,000 (US$4.4) as he had broken the rules.

While the learner declined, the teacher insisted that he pay the money as he had signed a commitment at the beginning of the course.

The teacher also stated that this was not the first time the student had violated the rules and that she would not continue teaching unless he paid.

After the learner called her a ‘fraud,’ she appeared to lose control and started yelling at him and using offensive words, including calling him “pig brain” and “pig face.”

“This is my playground, where my rules apply,” she asserted.

The verbal confrontation escalated as the learner fought back.

At the end of the clip, he threw his books on the floor and stormed out of the classroom, stressing that he would sue her and the center.

According to the student, he did his homework but left it at home.

He would hand it the following session, but the teacher underlined that it was a violation.

The English center highlights on its official website that “discipline of steel” is applied at the facility, stressing that fines from VND50,000 ($2.2) to VND100,000 must be paid if learners fail to hand in their homework on time.

A four-sided commitment between the center, teachers, learners and their parents is signed at the start of the course.

While the majority of viewers expressed their opposition to the teacher’s manners, some said she was right as the fines were clearly stated in the rules and commitment.
