Bepa rendarira
Chigadzirwa Chekutanga
Bheji rendarira rinoenderana neElectrolytic mhangura, trace uye trace zvinhu seyakaisa zvinhu, kuburikidza nekunyungudika, kutonhora kurwadza, kucheka, kupedzisa, uye ipapo kurongedza. Maitiro ekugadzirisa, eplasitiki, michina yemuchina, kupesana, kuita uye kwakanaka. Iyo yakashandiswa zvakanyanya mumagetsi, emagetsi, kutaurirana, Hardware, kushongedza uye mamwe maindasitiri
