1.Kukhudzidwa ndi kusintha kwa mankhwala ndi kupanga mapangidwe, kukula kwa makina enieni / kulemera kwa thupi kungakhale kosiyana, chonde tchulani mankhwala enieni.
2.Zithunzi zamtundu wamtunduwu ndizofotokozera zokhazokha, zotsatira zenizeni za mankhwala (kuphatikizapo koma osati mawonekedwe, mtundu, kukula) zingakhale zosiyana pang'ono, chonde tchulani mankhwala enieni.
3.Kuti apereke ziganizo zolondola momwe zingathere, kufotokozera malemba ndi zotsatira za chithunzi cha ndondomekoyi zikhoza kusinthidwa ndikusinthidwa mu nthawi yeniyeni kuti zigwirizane ndi ntchito yeniyeni ya mankhwala, ndondomeko ndi zina.
Zikachitika kuti zosintha zomwe tazitchula pamwambapa ndi zofunikadi, palibe chidziwitso chapadera chomwe chidzaperekedwa.
