Quite unreasonable, the school requires students to have a unified hairstyle: boys' short hair is between 1-3 cm; Girls have ear-length short hair, and bangs don't cover their eyebrows. If you can't do it, you will be dissuaded. The school also stipulates that shampooing should not be too frequent, and the interval between shampooing should not be less than three days. In view of the problem, the school strictly requires students to cut their hair short for the safety of students. Because most of the majors in the school belong to engineering, and there are many practical trainings in CNC machine tools and other majors, cutting short hair can reduce the personal safety hazards of students. What is the "Code of Daily Behavior for Middle School Students (Revised)" formulated by the Ministry of Education? The first article of the code reads: "Dress neatly, succinctly and generously, no perm, no hair dye, no makeup, no jewelry, no long hair for boys and no high heels for girls". Are some schools misinterpreting the norms issued by the Ministry of Education? Because most of the majors in this school are related to machine tools, it is reasonable to unify short hair. However, in recent years, some ordinary middle schools actually require students to have a uniform hairstyle. We adults love beauty, but don't children love beauty? The same hairstyle may be very different for different people. Inappropriate hairstyle will hurt children's self-confidence, unwilling to associate with others, and indirectly lead to weariness of learning. The frequency of shampooing depends on everyone's hair quality, such as oily hair. If you don't wash your hair for two days, your hair will shine and smell, leading to hair loss. The school has strict requirements for students' hairstyles and shampoo frequency, and it is across the board, claiming that everything is for the good of students! Are school leaders suspected of being irresponsible for this unreasonable regulation? Establishing rules and abiding by them is the key to strict management of schools. However, when making school rules, we should guard against "deviation", take it for granted less, do more practical research, listen to students' thoughts, and then study how to do management, so that there will be no "wonderful" school rules.
