If it's accidental and the symptoms are mild, it's nothing

(There are many things that have adverse effects in life, such as radiation on the Internet, so don't you go online? It's not good to skip breakfast, but how many people eat breakfast now? )

On the other hand, if it's serious, it won't work.

I won't accept students with severe rhinitis, students with tracheal problems and students under the age of nine who haven't changed their teeth.

It's for their own good. Learning is important, but health is the capital.

As a teacher, I should be responsible for students ~ ~
