Brushing his teeth

When i was walking in the early morning streets of China i notice everybody is getting ready for their daily routine. But something caught my eye. In this small rural village ,is not like the big city . Most of them brush their teeth and clean their faces at the side of the streets. Holding a jug ( basically metal cups) , a brush , toothpaste and a tower , they ought to do it outside at the street but not in the toilet like us. Why ? I am not sure but what i can tell is the people overhere shares public toilet. The public toilet is very different . The building of the toilet is ... of course a building, but it's no different from other buildings . Just 1 big building with a signboard 'toilet' . So what i do is i interview him . He says '... its the tradition and lifestyle here for generations..' ..well .. i guess its hard to see that certain parts are still hang up with the traditional and ancestors method in this very civilized time
