Icyayi kibisi gikundwa nabantu ibihumbi, kandi impamvu nyinshi zituma gikundwa nabakunda icyayi kibisi nuko icyayi kibisi gikura vuba.Icyayi kibisi gikunda igicucu nubushuhe, ntigishobora guhura nizuba, kandi gifite umuvuduko mwinshi.Muguragutunganya icyayi kibisiimashininaicyuma naizindi mashini z'icyayi, abahinzi b'icyayi barashobora kumenya igihe nyacyo kiranga kumera no gutoragura umunsi umwe, ibyo ntibizigama amafaranga yumurimo gusa, ahubwo biniyongera Isoko ryiyongera, kandi amababi yicyayi yo mu gitondo yo mu rwego rwo hejuru arashobora gutemba mumasoko kubiciro byemerwa cyane kubaguzi, kuzuza icyuho cyo gutoranya ibindi byayi, no guhuza ibyifuzo byabakunda icyayi kurwego runini.Byongeye kandi, icyayi kibisi gifite ibisabwa bike cyane kugirango habe icyuho.Ugereranije n'amababi y'icyayi akozwe mu nkono y'ibumba ry'umuyugubwe, icyayi kibisi gishobora guhitamo icyayi icyo ari cyo cyose n'icyayi cyashyizwe ku isoko, kandi gishobora kwerekana uburyo bw'icyayi.Byongeye kandi, icyayi kibisi gifite amazi meza asabwa.Icyayi kibisi gikeneye gusa gushirwa mumazi yo hagati kandi yujuje ubuziranenge nkamazi asanzwe yubutare namazi yo mumisozi, kugirango abakunzi bicyayi kibisi babone uburyohe bwihariye.

Muri iki gihe cyizuba, ikintu cyiza cyane nukuba mucyumba gikonje, hamwe numuyaga ukonje uhuha mucyumba, ukareba kuri icyayi kumeza, kumva amajwi atontoma, no kumarana umwanya wawe mumahoro.
