HUTONG alley, in Chinese; what in Chile we call conventillo, a passage where several families live with a common bathroom in the background. The kitchen is also communal. The bedroom has the sofa next to the bed. All rooms at the hutong face a square courtyard, but in the convent it is only the long passage. Beijing had 4500 Hutons until 2008, built during the Yuan, Ming and Qing dynasties.
