There are some old men who use recycled foam boxes to make surprising birds, dragons, elephants and air planes... as toys for kids. These talented men make these toys for kids which they can play with safely. They always have a story to tell the kids, too. One old man was telling a little girl where the elephant had been as he was painting it.
Some other old men use rice flour to model toys such as roses, soldiers with a gun, chickens, and lots of other different shapes.
It takes them about thirty minutes to finish these fun toys and sell them for about 5000Vnd each. This business is not new in Hanoi and I think it goes way back to some tradition.
