Kuongororwa kweBhurashi reMazino eMwana

Nemhaka yokuti muromo wemukanwa wevana uri padanho rekukura, hauna kusimba kana uchienzaniswa nemhoteredzo yemuromo yevakuru, kunyange muhutano hwenyika, chiyero chebhurashi remazino emwana chakanyanya kusimba kupfuura chevakuru vemazino, saka zvakakosha vana kushandisa bhurasho remazino remwana.

Zvichienzaniswa nebhurasho remazino revakuru, bhurasho remazino remwana richava nemusoro diki uye unochinjika webhurasho remazino kuti upinde mukati memuromo uye uchenese zino rega rega.Mukuwedzera, kuitira kuti vana vadzivise kumedza mazino akawandisa, chiyero chemazino chinowanzoita saizi yepea, uye chiso chemazino emwana chinogadzirwawo kuti chive chakamanikana.

Naizvozvo, bhurasho remazino remwana rinoda musoro mudiki uye mutete bhurasho remazino, matinji akatsetseka, uye bhururu rakatetepa, zvinova zvakanakira vana vane mukanwa madiki uye nemazino matete.
