Rivoningo i matimba ya ntumbuluko lama endlaka leswaku hikota ku vona.[1] Matihlo ya hina makota kuvona ntsengo wokarhi wa rivoningo, kasi kuna magandlati ya matimba ya rivoningo lawa hi kotiki ku mavona.[2][3]

Miseve ya dyambu yi voningela mapapa

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. Swiharhi swin'wana swikota ku endla rivoningo hi xirho xa karhi xa miri wa swona.
