Grandma died, and the grandson was filial. Is it okay to wear a hat?

The hat is just a form. On some occasions, Dai Xiao hat may affect work and study, so you don't have to wear it (for example, it is not appropriate for teachers to wear Dai Xiao hat in class, and it is indecent for people's police to wear Dai Xiao hat on duty ... and so on, you can wear it at home. If you really want to be a person who respects your elders, your luck will improve.

Internal filial piety is more important than external form.
