Xihlovo xa rivoningo laha misaveni i dyambu. Rivoningo ra dyambu ri haxa matimba eka swimilana leswkau swi kota to sweka chukele ra ntumbuluko leri nyikaka matimba eka swiharhi na vanhu lava dyaka swimilana sweswo. Ndzilo wa tihunyi na wona ixinwana xa swholovo swa rivoningo, kasi manguva lawa hi tirhisa ngopfu matimba ya gezi ku layitha timboni ta gezi.
