It is impolite and unethical to humiliate the appearance of others in a vague way, and this situation should not be encouraged or explored. As a teacher, it is more important to guide students to establish correct values and a sense of respect for others, rather than paying attention to possible humiliating words. At the same time, it is recommended that you treat these inappropriate behaviors of students with a peaceful and rational attitude, and through active communication with students, strengthening class management, and creating a good atmosphere between teachers and students, let them understand the importance of respecting others and avoid the breeding of such bad culture. If the student's behavior has seriously affected the teaching order or your psychological state, you can also consider communicating with the relevant departments of the school to jointly seek appropriate solutions. Don't let these negative behaviors unduly affect your work and mood. Believe that your value and charm in education are far more than your appearance.
