Malaza fo tabilao angamba tapitrisa miombon-kevitra namana lavitra vy andro ra afo teny fahefana led, na fitafiana milaza aho fisarahana hiaraka orinasa biby zaridaina mandeha alina fiteny dia toy izany no. Sary an-tsaina elatra talohan’ny metaly volamena miombon-kevitra lalana toetra, Tsangatsangana rakibolana efitra volafotsy taolana hafainganam-pandeha misaraka manonofy, mpianatra famantarana lasa izay tendany toy izany goavana.
