T&T PI U5 Ka

I wrote a report.
It’s about braille around us.
Braille is a good system for blind people.
It’s used on many items at home.

For example, we can see braille on cans
and remote controls.

Braille is used on many public items too.

For example, we can see braille on bus stop buttons
and mailboxes.
I want to learn more about braille.
