Choteteza mafunde

Pakadali pano pali mitundu iwiri ya zotchingira: zomatira ndi zokutidwa ndi pulasitiki. Poyerekeza ndi chitsulo wamba, chomatira chimakhala cholimba pang'ono ndipo chimawonongeka mosavuta ndi makina. Chifukwa chake, samalani panthawi yomanga ndipo chigwireni mosamala. Chomatira chikawonongeka, Dzazaninso ndi zinc yambiri mkati mwa maola 24 ndikuyikanso ngati pakufunika kutero.

Choteteza choteteza choletsa kugundana chiyenera kusinthidwa nthawi zonse panthawi yokhazikitsa. Chifukwa chake, mabotolo olumikizira ndi mabotolo olumikizira sayenera kumangidwa msanga. Dzenje lozungulira pa chotetezacho liyenera kugwiritsidwa ntchito kusintha mawonekedwe a mzere munthawi yake kuti mawonekedwe a mzere akhale osalala ndikupewa kusalingana kwapafupi.
