Yes, teachers should definitely give advice to students. They know what the students are good at in school, which helps them guide the students better. Teachers can see where a student might do well in the future and help them with that. They can also help students think about what they want to do after school, which is really helpful for their future.

I believe teachers should focus more on teaching their subjects and less on giving personal advice. They are experts in what they teach, not necessarily in a student's personal life. If teachers get too involved, it could make things complicated. It's important for them to maintain a professional relationship with students and not to cross that line. This way, they can keep their teaching clear and effective.

I think it really depends on what the advice is about. For example, if it's about choosing university subjects, teachers are usually good at giving advice because that's their job. But if it's about personal stuff like family or relationships, teachers need to be careful with what they say. Young people can be easily influenced, so teachers should stick to giving advice on education topics only.
