I don't support this kind of behavior. Students also have their own self-esteem. Why force them to shave their heads? I think it's acceptable as long as you dress appropriately and don't dye your hair too long. Moreover, from the psychological point of view, students with withdrawn, depressed and other psychological diseases can't use some compulsory means to hurt them, which will cause their serious psychological problems and even affect their future. I think schools can start with the following two points if they want to plan students' faces reasonably:

1, just respect the students and be decent.

When planning students' appearance, I think schools should follow the principle of "respecting students and being decent", that is to say, it is not difficult to ask students what they must do, and we can give them a general concept. For example, XXX is dressed appropriately today, so we should learn from him and take him as the standard in the future. Of course, if a student really doesn't listen, we can talk to him alone, but we can also talk to him.

2. Reject the opposite.

If the school must use a hard requirement to ask students, then I think it can use negative teaching materials to ask. For example, dyeing hair is not allowed, and any student who dyes hair will be severely punished and recorded. Then, when publicizing that some people who dye their hair are particularly ugly, gradually change the aesthetic standards of students from the side, so that students can slowly reject negative materials themselves.

Finally, I remembered that there is a stipulation in Huawei's goal that they always use a "general direction" when teaching employees, that is, they will not tell you what your clear goal is. It is correct to use "roughly like this", "roughly go forward" and "roughly where to work". Personally, I quite agree with this practice, because it not only leaves us a lot of room for self-development, but also respects our self-esteem to a great extent.
