Duviner ndi mtundu wapadera wa dupxer omwe amagwiritsidwa ntchito m'makankhidwe opanda zingwe kuti alekeretse ndi kulandira zizindikiro mu dolian. Ndemanga ya kavalidwe imakhala ndi mitu yambiri yosiyanitsa, iliyonse imayambitsa kulumikizana mbali ina.

Mfundo yogwira ntchito ya kambuku imakhazikitsidwa pa kusakonzekera pafupipafupi, yomwe imagwiritsa ntchito mawonekedwe owoneka bwino kuti muthandizire malembedwe osiyanasiyana. Makamaka, chizindikiritso chikatumizidwa mu duwa, chimatumizidwa kutsekeka kwakanthawi kokhazikika ndikukulitsidwa ndikuwafotokozeranso pafupipafupi. Nthawi yomweyo, chizindikirocho chimalandiridwabe m'malo ena osakhalitsa ndipo sadzafalikira kapena kusokoneza.

Zojambulajambula zomwe zilipo pempho.

Zigawo ziwiri zazikulu za duwa la ntchentche ndizomwe zimapatsirana ndikulandila.

Kupatula kwapamwamba, kutayika kochepa, kudalirika, komanso kukhazikika kwa miyala yamkati kumawapatsa zabwino m'makankhidwe opanda zingwe.

Mimba yamitchire imagwira ntchito yofunika kwambiri m'makankhidwe opanda zingwe, makamaka makamaka pazochitika zomwe onse kutumiza ndi kulandira zizindikiro zimafunikira kukhazikika mu gulu lofananira ndi pafupipafupi. Mwachitsanzo, kulumikizana pakati pa malo oyambira ndi zida zam'manja
