Sudan is an extremely hot country, in my memory, the temperature in Sudan is always up to 40 degrees, the hot sun can kill flies, so in fact, this place is littered with garbage, but actually rarely see flies. Sudanese like to drink coffee, people brave the heat, sit on the floor, three groups, two pairs sitting in the shade of the trees and not stopping to coffee, this is the most coffee-loving country I have seen, the other country is Ethiopia.
