There are lots of organizations helping blind people to make lots of different products such as brooms, incense, feather dusters and tooth picks. That's why you can see them easily on the street. I really admired these people who try to earn a livelihood instead of being beggars. They only make a small income. What amazes me more is that they don't get killed or injured wandering through the crazy Hanoi traffic without full vision.
Most of the brooms are made from bamboo and coconut trees and certain types of grass while the dusters are made from chicken and duck feathers. I wonder if the bird flu is also having an effect on the productions of them.
